Description

The present invention relates to a laboratory device with an operating and / or control and / or regulating device.

Such a laboratory device is typically used for conveying, mixing, demixing, heating, shaking, shaking, drying and / or distilling products and product mixtures. For example, a rotary evaporator is used to concentrate (concentrate) solutions, dry the solid portion in solid-liquid mixtures, evaporate solvents, and separate liquid mixtures into the respective components. The evaporation of a certain liquid component occurs under certain conditions (temperature and pressure), since the enthalpy of vaporization of a substance is both pressure, and also temperature-dependent.

In order to achieve a better evaporation rate of the evaporator flask is set in rotation, which brings a thin liquid film on the inside of the piston wall and thus a larger evaporation surface with it.

In a rotary evaporator, the starting material (liquid, liquid mixture or solid-liquid mixture) is heated within the evaporation flask by means of heating or heating bath.

The interior of the preferably closed system consisting of evaporating flask, steam guide tube, glass cooler and condensate flask is evacuated by means of a pump in order to generate a specific negative pressure which allows the gaseous portion to migrate in the direction of the colder glass cooler and to condense there. The condensate drips into the condensate piston below the glass cooler. Under certain conditions (temperature and negative pressure), the remaining liquid begins to boil or evaporate. The lower the vacuum pressure, the lower the necessary temperature for evaporation.

Among other things, it is important to set the temperature of the heating bath, the rotational speed and the negative pressure in accordance with the boiling behavior of the component to be evaporated and optionally correct and / or change during the evaporation process. Furthermore, it may also be necessary, for example, to suitably set a cooling temperature in a cooler connected downstream of the evaporation flask and / or an immersion depth of the evaporation flask in the heating bath.

In particular, if the control or regulation of these exemplified electronic components of the rotary evaporator via a central control and / or control unit, this has a variety of different processes and settings to allow and therefore must have a suitable menu, which an operator access the different applications allowed. However, the large number of operating and control functions can also lead to a relatively confusing and / or complicated menu navigation or operation of the laboratory device.

The object of the present invention is therefore to provide an improved operating and / or control device for a laboratory device, with which it is in particular possible in a simple manner or with a clear and / or simple and / or intuitive menu navigation and / or customizable user interface to centrally control the individual electronic components of the laboratory device and / or to provide an improved operating and / or control device for a laboratory device, which can be used in particular for various laboratory equipment, ie which can be used flexibly.

The object is achieved by a laboratory apparatus according to claim 1 and a laboratory apparatus according to claim 2. Further developments of the invention are given below or in the subclaims.

A laboratory device according to a first aspect of the present invention comprises an operating and / or control and / or regulating device with a display with a touch-sensitive surface, on which individual picture elements can be displayed, which are assigned to application programs for the laboratory device. The picture elements can be displayed on spatially limited fields and an application program is activated by touching the associated picture element with an actuating object or by approaching an actuating object to the associated picture element. The picture elements are individual, i. free or optional, selectable and / or positionable on the display.

The application programs, also referred to as applications or apps, can for example specify and / or display control parameters for electronic components of the laboratory device and / or display current measured values or operating values (eg temperature, pressure or rotational speed in a rotary evaporator) and / or display options for the display specify and / or provide input options for other applications. The application programs thus serve, on the one hand, the display of information relating to the laboratory device, as well as the operation or control of the laboratory device or its operating state. The application programs assigned picture elements may also contain text or lettering in the form of short keywords and / or numerical values in addition to or instead of images.

The spatially limited fields offer arrangement possibilities for the picture elements. In this case, a picture element does not have to be arranged on exactly one field, it can, for example, also extend over a plurality of fields and thus, for example, be made larger in comparison with another picture element that is merely positioned on one field.

By arbitrarily selecting and positioning the picture elements on the display, it is possible for a user, for example, to create a layout of the user interface (display display) that corresponds, for example, to a particular intended use or application of the laboratory device (in the case of a rotary evaporator as a laboratory device, for example, a concentration process (concentration) of solutions or the separation of a liquid mixture in the components) is adapted and / or adapted to a particular laboratory device, especially when operating various laboratory equipment with the same control and / or control and / or regulating device , Alternatively, the user may also select an example factory, i. when acquiring the operating and / or control and / or regulating device, use already existing selection of application programs and rearrange or arrange the picture elements assigned to them according to their wishes to a layout of the user interface. Further, by means of the control elements which can be positioned on the display, it is possible, for example, to supplement the operating software in the future with further application programs (apps) which are loaded onto the user interface or into new pages that can be displayed on the display.

The display thus represents a graphical user interface of the laboratory instrument, i. it allows the control of the laboratory apparatus by touching graphic symbols, i. the picture elements, and optionally by means of further controls. For this purpose, the operating and / or control and / or regulating device may include a CPU whose operation is controlled by a computer program (software).

A laboratory device according to a second aspect of the present invention comprises an operating and / or control and / or regulating device with a display with a touch-sensitive surface, wherein on the display individual picture elements can be displayed, which are associated with application programs for the laboratory device. The picture elements can be displayed on spatially limited fields and an application program is activated by touching the associated picture element with an actuating object or by approaching an actuating object to the associated picture element. In this case, at least a first selection of picture elements is provided, wherein the first selection of picture elements is adapted to a first method that can be carried out by the laboratory apparatus and a second selection of picture elements is provided, wherein the second selection of picture elements is based on a second, preferably of the first method various, practicable with the laboratory device method is adapted.

Depending on the laboratory equipment used, methods that can be carried out with the laboratory apparatus can be, for example, the conveying, mixing, demixing, heating, shaking, shaking, drying and / or distilling of products and product mixtures. Examples of processes that can be carried out in a rotary evaporator can be the concentration of solutions, the drying of a solid fraction in the case of solid-liquid mixtures, the evaporation of solvents and / or the separation of liquid mixtures into the respective components. The methods that can be carried out with the laboratory device can thus be in the type of operated (electronic) components of the laboratory device (in a rotary evaporator eg heating bath, vacuum pump, rotary drive, vertical drive, valves, etc.) and / or in an operating state of at least one (electronic) component of Laboratory device differ from each other. By operating state is meant a state in which the laboratory device or its component is operated, for example a temperature of the heating bath or a speed of the rotary drive or immersion depth of the rotary piston, etc. and / or a switched on or off state of the laboratory device or its component.

Characterized in that on the display different selections of picture elements, hereinafter also referred to as application-specific layouts or user interfaces, can be displayed, which are adapted to different purposes of the laboratory device, it is for example in a simple manner, the laboratory device for the particular purpose use. In particular, not all the display elements provided for the display elements must be displayed on this, but it is possible, for example, only display such pixels as application-specific layout on the display, which are also required for the intended use of the laboratory device or for the laboratory equipment used. Thus, a simple and intuitive operation for the laboratory device is provided. The first and the second selection of picture elements, ie the first and the second application-specific layout, can also be linked to the use of the operating and / or control and / or regulating device with a first and a second, of which first be adapted to different, laboratory equipment. For example, a first selection of pixels may be adapted for use with a rotary evaporator and the second selection of pixels for use with a shaker and mixer.

The invention is not limited to providing two different application specific layouts, more than two application specific layouts may be provided within the scope of the invention. In this case, the different application-specific layouts can be provided, for example, on different sides of a (main) displayable on the display and / or an application-specific layout can be selected for display on the display, for example by means of a menu of the display or a functional level. An application-specific layout may already be provided in advance (for example, at the factory) for the operating and / or control and / or regulating device and / or it may be a selection of picture elements selected or compiled by a user himself.

The features and developments mentioned below can relate both to the laboratory apparatus according to the first aspect of the invention and to the laboratory apparatus according to the second aspect of the invention.

Preferably, the operating and / or control and / or regulating device is modularly expandable and / or at least partially adaptable, for example by selecting application programs from an application program library and / or arranging or positioning the assigned picture elements on the display. This makes it possible, for example, to enable a wide variety of applications and to read out and / or operate various additional components (for example sensors or actuators) and to analyze, store or load collected data from the database.

Preferably, a picture element is a numerical value, preferably in combination with the respective unit, and / or a graphic symbol. More preferably, numerical values are combined with corresponding graphical symbols on the display display, for example by selecting and arranging corresponding picture elements. This provides, for example, a clear and intuitive user interface.

Preferably, a picture element is further provided which represents a status display for graphically displaying an operating state of the laboratory device or at least one (electronic) component of the laboratory device. An operating state may be an on or off state or refer to an operating value or measured value of the laboratory device or its component, e.g. indicate an overshoot and / or undershoot of a preset actual or setpoint. More preferably, the picture element corresponding to the status display comprises two different graphical states which can be displayed on the display. This makes it possible, for example, in a simple manner different operating states of at least one (electronic) component of the laboratory device in a simple manner on the display graphically, with a first operating state (eg "on") of the component (eg a heating or a Rotational drive of a rotary evaporator) is represented by the first graphical state of the picture element and a second, different from the first operating state, second operating state (eg "off") of the component is represented by means of the second graphical state of the picture element. The first and the second graphical state may differ, for example, by a size and / or color of the picture element or comprise two different graphical, preferably similar, symbols.

Preference is further given to predetermined parameter sets (set at the factory or by a user), for example sets of desired values for the operation of the laboratory apparatus. The predefined parameter sets can be stored, for example, as favorites and thus quickly and easily selected or loaded. This makes it possible, for example, to save used parameter sets and load them again for later processes, which increases the reproducibility and comparability of the processes. Also, for example, certain parameter sets can be stored for certain starting materials.

The touch-sensitive surface operation object (touch screen) may be, for example, a finger or a user's fingertip and / or a pen, e.g. a touchpad stylus, his. The actuation object can also be, for example, a glove or a gloved finger / fingertip of a user. Preferably, the sensitivity of the touch-sensitive surface is adapted for the use of common in the laboratory field gloves with a certain material thickness.

The touch-sensitive surface may be, for example, a touch-sensitive screen that operates resistively or capacitively, or else a surface of a display that is already approaching the actuating object for example, reacts via proximity sensors, so that the operation of the touch-sensitive surface no direct contact must be the same. Thus, for example, a simple, intuitive and versatile way to operate the touch-sensitive surface is given.

Preferably, the spatially limited fields form a grid of squares and / or rectangles. Thus, for example, a simple, clear surface for the arrangement of the picture elements is given. For example, the fields can set the size of the picture elements displayed on them. The fields do not all have the same size and / or shape, but it is also possible to provide differently sized u / o differently shaped in their shape.

Preferably, a main plane can be displayed on the display, in which a number of picture elements can be positioned and wherein a functional level can be displayed on the display by touching one of the picture elements of the main plane with the actuating object or by approximating the actuating object to the picture element, in which at least one further Picture element is provided which allows input and / or display of data of the image element of the main level associated application program. As a result, for example, the display is made clearer, since the number of pixels in the main level itself is reduced or various functions such as the display of a (set) value and the adjustability of the (set) value are implemented in different levels of operation. More preferably, a picture element of the functional level is a virtual keyboard or a scrollbar or otherwise data entry option, preferably combined with a display of the input data. For example, a simple, intuitive and fast input of data is possible.

For example, a main-level picture element may indicate a target value for an electronic component of the laboratory device, and a functional level may be displayed on the display by selecting the picture element (by touching or approaching the actuating object) instead of the main plane. In the functional level, for example, a first picture element may be displayed, which is a number field (virtual keyboard) for inputting the target value and a second picture element which is an indication of the set target temperature. Thus, the display serves as a combined input and output device for controlling the laboratory device.

Preferably, the maximum number of functional levels assigned to a picture element of the main level is one. This provides, for example, a simple menu navigation in which the user is not in functional levels, i. Lower levels of the main level, loses.

Preferably, at least one further picture element of the main plane represents a menu from which a first functional level is opened by touching the picture element with the actuating object or by approaching the actuating object to the picture element with further picture elements to which a second functional level is assigned in each case, and wherein preferably the maximum Number of levels is three. By means of the additional second functional level, for example, the menu functions in the first functional level can be displayed and the adjustability of the menu functions in the second functional level can be carried out. As a result, for example, an extensive menu can be provided, which is accessible via only one picture element from the main level and the main level is thus clearly arranged. The menu may include, for example, settings for basic functions, such as e.g. Time, language, units for setpoint and measurement values, etc., which are not directly related to the operation of the laboratory device.

Preferably, the display is adapted to represent a first side of a main plane or a first side of a functional plane, wherein the main plane or the functional plane comprises at least two sides and wherein by a wiping movement of the actuating object on the display another side of the main or functional level can be displayed on the display. Arranging the picture elements on several sides of the main and / or functional level (s) makes it possible, for example, to arrange a larger number of picture elements in the respective level without the display of the corresponding level on the display becoming confusing. The swipe facilitates a quick and easy page break between different sides of a plane. The page change can, for example, horizontally, ie laterally, i. from right to left or vice versa, and / or vertically, i. upwards or downwards and / or diagonally.

Preferably, a main plane and / or a functional plane comprises at least one header and / or footer and / or a marginal column with picture elements, wherein the header and / or footer and / or marginal column is preferably optically highlighted and / or preferably at least one pixel of the Header and / or footer and / or the marginal column is maintained at a change between different sides of the main and / or functional level. This can be arranged in the header or footer or the marginal column picture elements, for example, a navigation between different pages of a layer and / or between different layers. These pixels are thus not the actual control or operation of the laboratory device, but the menu navigation in the display. It is also possible, for example, to provide picture elements for rapid control (for example switching on and off) of a component of the laboratory device (eg the heating bath in a rotary evaporator) in the header or footer or edge column so that the respective component of the laboratory device can be quickly and easily read Way is controllable.

Preferably, the operating and / or control device is connected or connectable to a data memory containing further application programs, preferably in a program library, and wherein the application programs are freely selectable and positionable associated picture elements or arrangements of picture elements in the main and / or functional level are. Thus, for example, the display display can be made variable or individually configured and can thus be used e.g. be adapted to a laboratory device and / or its intended use. In addition, the display can be equipped or supplemented, for example, with newly developed applications or application programs.

Preferably, by means of a duration of touching a picture element or approaching a picture element, it is possible to control whether an explanatory window is displayed in the display by means of text and / or a picture and / or an animation (video), preferably a picture Guidance or assistance in the operation of the picture element is given. The explanation further simplifies the operation or control of the laboratory device. For example, with a brief period of time (e.g., less than 1 second) of touching or approaching a pixel, the associated application program may be activated, and with a longer duration (e.g., over 1 second) of touch, the associated explanation may be displayed.

Preferably, the operating and / or control device additionally comprises mechanical and / or electrical operating means, for example control buttons and / or operating wheels. By way of example, a superordinate function, such as e.g. the switching on and off of the display, the control or operating device and / or electronic components of the laboratory device, are controlled. In addition, the operating means can be used for example instead of or in addition to virtual controls of the display for data entry. Thus, for example, alternative means for data input or control of the laboratory device are provided.

The laboratory device may comprise a housing and the display may be provided on the housing. Alternatively, the laboratory device may also include an external control or operating device on which the display is provided and which with the laboratory device via data transfer by means of a cable or wirelessly (eg via WLAN, LAN (eg Ethernet), Bluetooth, USB - or RS232 interface) can communicate. Thus, the operating device can either be formed integrally with the laboratory device, or it can be provided separately from the laboratory device. In the latter case, the same operating and / or control device can also be used, for example, for controlling a plurality of and / or different laboratory devices.

The laboratory device is preferably designed as an evaporator, in particular as a rotary evaporator, or as a stirring device, in particular as a magnetic stirrer or shaking and mixing device. By operating and / or control and / or regulating device described above, for example, the operation or control of such a laboratory device can be simplified.

Preferably, the operating and / or control device and / or the display is provided as a kit for retrofitting or retrofitting the laboratory device. This makes it possible, for example, to retrofit an existing laboratory device with such an operating and / or control and / or regulating device and / or such a display.

Preferably, a main plane and / or a functional plane comprises a plurality of displayable sides and the sides comprise at least a first side and a last side, wherein a swipe of the actuating object via the display, a direct change between the last and the first side achievable is or vice versa. For example, this direct change avoids the user having to scroll back and forth through all the pages when displaying the last page on the display in order to return to the first page, which further simplifies the operation of the display, for example.

The following is with reference to 1 An embodiment of the present invention is described. This in 1 The laboratory device shown is a rotary evaporator 1 , The rotary evaporator has a housing 16 on. For receiving a starting material, it comprises an evaporation flask 2 , which by means of a rotary drive 9 is rotatable about an axis of rotation. The evaporation flask 2 For example, it may be configured as a glass round bottom flask. The starting material may be a pure substance or a mixture and is in the liquid and / or solid phase in the evaporation flask 2 in front. It contains the substance to be evaporated.

The evaporation flask 2 is in a heating bath 3 arranged with a heatable liquid, such as water or oil. About one in 1 not shown vertical drive is the immersion depth of the evaporating flask 2 in the liquid of the heating bath 3 adjustable.

Next contains the rotary evaporator 1 a capacitor 4 which via a steam passage 5 , a steam supply 6 and optionally an expansion vessel or precooler 7 with the evaporating flask 2 connected is. The evaporation flask 2 and the capacitor 4 preferably form a gas-tight system with the elements arranged in the vapor path between them. Further, the capacitor has 4 a vacuum connection 8th on to connect a in 1 Not shown vacuum pump for generating a negative pressure to a vacuum in the gas-tight sealed system. For supplying and removing a coolant are connections 12 intended. Next points the capacitor 4 an outlet valve 11 for the condensed distillate.

Furthermore, the rotary evaporator comprises an operating unit 10 for controlling the rotary drive 9 , the heating bath 3 , a vacuum pump and the vertical drive and optionally the distillate outlet valve 11 and the coolant connections 12 or the coolant circuit. The operating unit 10 can, for example, on the housing 16 but it can also be separate from the rotary evaporator 1 be provided and communicate with this via a cable connection or wirelessly, for example via WLAN or Bluetooth.

In operation, first a starting material containing the substance to be evaporated, in the evaporation flask 2 filled. Then the evaporation flask 2 through the rotary drive 9 set in rotation. By immersion in the heating bath 3 and / or applying a negative pressure, by which the boiling temperature of the solvent can be reduced, the solvent is evaporated from the starting material. By the rotation of the evaporation flask 2 On the inside of a thin film, such as a liquid film, the starting material is generated so that the surface of the starting material is increased and the evaporation is accelerated. About the steam passage 5 , the steam supply 6 and optionally the precooler 7 the vaporized solvent enters the condenser 4 where it is cooled and condensed to the distillate. The liquid distillate flows through the outlet valve into a 1 Not shown collecting piston and can be removed there.

Target values for the various electronic components of the rotary evaporator 1 be doing before and / or during the evaporation process by means of the control unit 10 set by the user. It is also possible to use pre-set target values (ie values already stored in the operating unit). Preset target values may, for example, be provided at least partially as a solvent database already present in the favorites list for easy access to the target values. This list of favorites can be supplemented at any time by individual favorites. In addition to the preset values preset as favorites (so-called manual mode), the preset setpoint values can also be used as ramp profiles with a predefined time specification according to which the various setpoint values pass through to "drive through" the control, ie to be called one after the other (so-called ramp profile mode). In this case, it is possible, for example, to choose between a direct jump to the next setpoint value and a linear approach to the next setpoint value. After the entire ramp profile has been completed, the basic parameters (rotation, heating bath, vacuum pressure, etc.) are held or stopped according to the preselected status ("static values"). The status of the piston with respect to the heating bath can also be provided as a basic parameter. Should z. B. the piston are left in the heating bath, the piston is held by the vertical drive (motor lift) down. If the piston is to be removed from the heating bath, it is driven out by the vertical drive (motor lift). As another mode, an automatic mode may be provided in which an evaporation process is automatically controlled by a single or multiple mixture. The various modes described may, for example, be provided to the operating unit as application-specific layouts, which will be described in more detail below.

Such desired values can be, for example, a vacuum that can be generated by the vacuum pump and / or a temperature of the heating bath 3 and / or a rotational speed of the evaporating flask 2 and / or a cooling temperature in the (pre-) cooler 7 or 4 and / or an immersion depth of the evaporation flask 2 in the heating bath 3 be. In operation, the electronic components of the rotary evaporator 1 through the control unit 10 controlled with reference to the predetermined target values. The operation of the rotary evaporator 1 can preferably at any time by means of the operating unit 10 by stopping, stopping or starting by touching the corresponding picture elements (see below). Preferably, mechanical pusher-turning wheels (see below) are coupled to the associated soft switches or picture elements in the display of the operating unit, so that the user can preferably intervene in both processes in the running process to change target values or components of the rotary evaporator (z. B. the rotary drive, the heating or the vacuum pump) on or off.

Preferably, a mechanically operated switch (short-stroke switch standby) for the operating unit 10 provided that a shutdown of all the basic functions of the rotary evaporator (rotary drive, heating bath, possibly vacuum and possibly motor lift start) without interrupting the entire power supply to the rotary evaporator, ie without the entire rotary evaporator is de-energized. This makes it possible, for example, the rotary evaporator via a wired and / or wireless remote control and, if necessary, turn off again.

In the 2a and 2 B shown operating unit 10 has a display 20 on, as well as optional additional mechanical and / or electrical control buttons 51 and / or operating wheels 52 , By means of the control buttons 51 and / or operating wheels 52 can, for example, turn on and off the display 20 and / or a power saving function or an idle state of the display 20 be controlled and / or they can be used for data input and / or allow direct control of the rotary evaporator, such as the heating of the heating bath.

the display 20 has a touch-sensitive surface, ie it is designed as a touch screen. The display shows different picture elements 30 . 31 on, ie on the display 20 are different picture elements 30 . 31 represented. Each picture element is assigned to an application program, also called application or app, which will be described in more detail below.

According to the invention, the picture elements 30 . 31 can be arranged arbitrarily on the display, ie positionable, so that the user can select, for example, from an application library or from a menu applications and arrange the corresponding picture elements according to his wishes on the user interface or position. 2a and 2 B show two different arrangements of the same selection of picture elements, wherein the arrangement of the picture elements is adapted in each case to the shape of the display, which in 2a is dimensioned larger in the vertical direction than in the horizontal direction, and in 2 B dimensioned smaller in the vertical direction than in the horizontal direction. In the 2a The user interface shown has an optional header 21 and an optional footer 22 on. For example, in the header, there is one pixel 30 , which represents a menu arranged, as well as other picture elements 31 that display a time, for example. In the footer 22 are for example picture elements 31 arranged whose application programs directly control various components of the rotary evaporator, such as the heating of the heating bath 3 switching on the vacuum pump and / or switching on and off all electronic components of the rotary evaporator and / or the opening and closing of the distillate outlet valve 11 , Since the in 2 B shown user interface in the horizontal direction has a larger dimension than in the vertical direction, the pixels are 30 . 31 the header and footer here in (also optional) marginal columns, ie in each one provided on the left and on the right edge of the display column 23 . 24 arranged.

For positioning the picture elements on a display (ie the user interface), this is like in 3a and 3b shown in a Split grid, where the grid is spatially limited fields in the form of squares 40 and / or rectangles 41 having. The squares 40 and rectangles 41 are arranged in rows and columns of the grid. This in 2a The display shown has an upper and a lower row of equal size rectangles 41 on, the header 21 or the footer 22 of in 2a correspond to the displays shown. Between the header and the footer are equal squares 40 intended. By positioning the corresponding picture elements 30 . 31 in the squares 40 or rectangles 41 of the grid will be the in 2a achieved user interface shown. It can be a picture element 30 . 31 exactly on or in a square 40 or rectangle 41 be positioned. The picture element 30 . 31 However, it can also cover several fields (squares 40 or rectangles 41 ) so that it is, for example, larger than other picture elements which extend over fewer fields or are positioned in only one field. The fields 40 . 41 thus define the possible positions for the picture elements 30 . 31 firmly. When arranging the picture elements in the fields 40 . 41 The grid area does not have to be all squares 40 and rectangles 41 On the contrary, it is also possible to leave individual fields blank.

Analogous to 3a shows 3b a grid of equal-sized squares 40 and rectangles 41 for the positioning of picture elements 30 . 31 for the in 2 B shown display. The grid area has left and right marginal gaps 23 . 24 from rectangles 41 on and between squares arranged 40 , The margins 23 . 24 Here are the colors of the squares in between 40 lifted and thus visually differentiated, but they can not even from the intervening squares 40 be lifted off. Optionally, also another column 23 ' of squares 40 , which to the left margin column 23 adjoin this, be assigned to more fields 40 . 41 in the marginal column 23 available. Similarly, the right margin column can 24 and / or the in 3a shown header and / or footer 21 respectively. 22 be extended.

In the 3a shown footer and / or header 22 respectively. 21 can also be highlighted, eg by colored highlighting of the corresponding rectangles 41 , In the 2a . 2 B respectively. 3a . 3b shown user interfaces can optionally have a graphic page display 44 which are described below with reference to 5 and 6 is explained in more detail.

4 shows the operation of the display 20 the control unit 10 , On the display 10 is a main level H with picture elements 30 . 31 shown. In the lower right corner of the display is a picture element 31 shown, which is a target temperature of the heating bath 3 indicates, ie the picture element 31 is associated with an application program that controls the setpoint temperature of the heating bath, eg by controlling a heating device of the heating bath 3 , where the picture element 31 the set target temperature in the main level H the display shows. By touching the picture element 31 with your finger or fingertip 18 the application program (control of the setpoint temperature) is activated, ie a new user interface or a new display window opens in the display 20 which is the picture element 31 assigned functional level F1 represents. In the functional level F1 are as further picture elements a virtual keyboard 31 " (Also referred to as input element or input field) for inputting data, ie for setting the target temperature, and a display element 31 ' provided for displaying the set target temperature. With the virtual keyboard 31 " the desired setpoint temperature is entered (by touching the corresponding numerical values with the fingertip 18 ) and then, by touching the virtual keyboard hook, this numerical value is taken as the new target temperature, the functional level F1 closed and the main level H shown again on the display. The picture element 31 in the main level H to display the set temperature of the heating bath 3 now also displays the newly set value. The associated application program controls the heating device of the heating bath so that the selected target temperature in the heating bath can be achieved. This can be done immediately after setting the new target temperature, or only when the user himself heating the heating bath by means of a corresponding pixel 31 and / or a control knob 51 and / or a control wheel 52 initiated.

Optionally, a data input or the setting of a desired value by means of a provided on the control unit mechanical control element, z. B. by means of a control knob 51 and / or control wheel 52 , which is preferably formed as a push-turning wheel. For this purpose, the corresponding mechanical control element is coupled to the virtual keyboard, ie, by turning the push-turn wheel, the input value can be alternatively or additionally corrected to an input by the virtual keyboard up or down. Preferably, the assignment of the control element to a virtual keyboard is graphically displayed on this, for example, by a provided around or on the push-turn or mechanical control LED ring (chain), when assigned to a virtual keyboard in a different form and / or color and / or sequence light up to visually distinguish the rotational adjustment (data input) to a mechanical operating element otherwise assigned function (eg Heizbad- or vacuum pressure adjustment).

Activation of the application program may also be accomplished by touching the corresponding pixel with another actuator 18 take place as the user's finger, for example by means of a pen, in particular a touchpad pen, or a glove. Preferably, the display surface is suitable for use with various operating objects, for example gloves made of different materials and / or with different thicknesses. However, an application program can also already react when approaching the actuation object (for example via proximity sensors), ie there is no need for direct contact with the display surface itself. Activating the application program is done by briefly touching the picture element ("tapping"), for example, if the picture element within a period T1 of 1 second is touched. On the other hand, the picture element becomes longer, ie during a period of time T2 > 1s, preferably T2 > 2s, an optional explanation window in the display can be displayed, at least for a short time, in which a text (info text) and / or a picture and / or a video animation provides an explanation, preferably an instruction or assistance with the operation of the picture element or of the associated application program.

5 shows the operation of the menu 30 , By touching the picture element 30 the main level H opens a first functional life G1 in the display with further picture elements 31 (first menu level). From this, the operator can select other applications, such as "Settings" or "App Basics" by touching the corresponding picture element, followed by a second functional level G2 (second menu level), which includes corresponding selection options and / or setting options. In the example of the functional level G2 the user can by touching the corresponding picture element 31 select the language in which picture elements and / or explanations are shown on the display.

The second functional level G2 includes several pages G2 . G2 ' . G2 " . G2 '" with picture elements provided therein 31 , ie different user interfaces (displays) for the same functional level (see also 6 ). By swiping with the actuating object on the display, a change between different sides of the functional level can be achieved. In this case, the wiping movement or the page change, for example, horizontally (ie, laterally, ie from right to left or vice versa) or vertically (ie from top to bottom or vice versa). By providing multiple pages for a (functional) level, for example, more pixels may be positioned than on only one page. In addition, the arrangement of the picture elements is clear, since the pages are arranged parallel to each other (ie via a swiping), making them easier and faster accessible to the user compared to an arrangement in a nested menu with other levels (ie a higher hierarchical system) ,

For better orientation between the pages, ie for the user to quickly recognize on which side of a (functional) level he is currently located, an optional graphical page display can be displayed on the pages 44 , also referred to as page navigation menu, be provided. The page display 44 For example, it includes a number of symbols (eg, points) corresponding to the number of pages of the (functional) level, the symbol corresponding to the page currently displayed on the display being optically highlighted, such as by changing the color and / or size has other symbols (assigned to the other sides). The symbols are arranged according to the arrangement of the pages. For example, if the paging is horizontal, then the icons are the page display 44 preferably arranged laterally next to each other. For example, if the page break is vertical, the icons of the page display are preferably superimposed. Additionally or alternatively, the arrangement of the symbols of the page display is preferably adapted to an alignment of a header and / or footer and / or edge column. Long lists can preferably be scrolled vertically, partially the position can be indicated by a slider. A graphical page display is preferably only on horizontal (horizontal) wiping to the next page, right or left next to it.

Preferably, there is a direct change between the first page G2 the second functional level and the last (here fourth) page G2 '" the second functional level possible. This means that if the last page G2 "' on the display 20 is displayed, which in 5 right of the first three pages G2 - G2 " is arranged, the first page G2 again on the display 20 can be represented by a wiping movement with the actuating object via the display (here, for example, from right to left) takes place. Thus, not all the intervening pages must first again G2 ' . G2 " on the display. Similarly, if the first page G2 is shown on the display, by a swipe movement with the actuating object, the last page G2 '" displayed on the screen without interrupting the pages G2 ' . G2 " to show on the display.

In 5 is still activating the functional level F1 shown the picture element 31 is assigned and to set a Rotational speed of the rotary drive 9 serves. The setting of the rotational speed is carried out analogous to that with reference to 4 described setting a target temperature. Analogously, it is also possible, for example, to set a negative pressure in the closed system, for example by controlling valves (for valve-controlled pumps) or a speed (for speed-controlled pumps), and / or switching on and off the condenser (circulation cooler) and / or the latter Enter target temperature.

G2 '" the second functional level of the menu, as well as the first functional level G1 of the menu, with pixels arranged therein 31 . 30 , A change between different sides of a plane takes place, for example, by a lateral wiping movement. Preferably, as described above with respect to 5 described, a direct change between the first and last and the last and first page of a level possible. The page display 44 is provided below the footer of the pages.

In the header of the various pages, for example, a picture element pointing at a hook may be provided for accepting changed settings, as well as a cross-pointing picture element for rejecting changed settings.

Alternatively, a pixel may be represented by a graphical display (eg, a background of a different color) as a selected pixel, ie, a pixel touched to the actuator. For example, touching a picture element displaying a home symbol may cause the first page of an application to be opened or a change to a higher level (ie, from the second to the first functional level or from the first functional level to the main level). The first page of an application, for example, the start page of the application z. B. with the graphically illustrated evaporator. the display 20 can also show a startup display when you turn it on, such as a logo

The in the 2a to 6 shown user interfaces of the main and functional levels show only exemplary arrangements of the picture elements. For the purposes of the invention, the picture elements are arbitrary or can be arranged as desired by the user on the display or in the main and functional planes or their various sides and is not limited to the arrangements shown here. Furthermore, the user can select any applications and arrange the corresponding picture elements at will on the display display, ie the user interface can be put together by the user individually for his requirements. The picture elements can also already be provided in advance on the display display, so that the user can merely rearrange or sort them, ie they can assign other arrangement fields to them.

Individually configurable applications can also be provided, which at the beginning consist of an empty home page and possibly further pages, a page change being effected by a wiping movement described above. These can be individually filled with individually selected by the user picture elements and preferably stored under its own name (via a virtual alphanumeric keyboard) as an application. For example, an application-specific layout described below can be created by the user himself. The picture elements can be selected, for example, from a previously provided library and arranged arbitrarily on the pages based on the grid. Also, pages already stored can preferably be changed and saved again.

The following is with reference to 7a to 8c A second embodiment of an inventive control and / or control and / or regulating device for in 1 shown laboratory device described. In particular, the operating and / or control and / or regulating device comprises various application-specific layouts for the display 20 , where each application specific layout is adapted to a specific purpose of the application in 1 adapted rotary evaporator is adjusted. An application-specific layout includes a specific selection of on the display 20 displayed pixels, the application programs for the rotary evaporator 1 assigned. An application-specific layout may already be provided in advance (for example, at the factory) and / or may be a selection of picture elements selected or compiled by a user himself. Preferably, the displayed application-specific layout is dependent on the components of the rotary evaporator connected to the operating unit, more preferably one of the picture elements displayed on the display being adapted to the connected components, ie if a component (eg a vacuum pump) is not connected to the operating unit is connected, the associated pixels are preferably not shown on the display.

7a shows a first on the display 20 displayed application-specific layout, ie a first selection of pixels, which for example a basic application of the rotary evaporator 1 , ie a first with the Rotary evaporator feasible method, serving in the only heating bath 3 and the rotary drive 9 operate. 8a shows a second on the display 20 displayed application-specific layout, ie a second selection of picture elements, which for example for a distillation operation, ie a second feasible with the rotary evaporator method is used, and in addition to the heating of the sample by means of the heating bath 3 and rotating the evaporating flask 2 by means of the rotary drive 9 also the application of a negative pressure by means of a vacuum pump (in 1 not shown), the cooling of the evaporated solvent by means of the condenser 4 and a temperature detection by means of another (in 1 not shown) comprises temperature sensor.

Alternatively, the right, on the control unit 10 outside the display 20 provided push-turn wheel (eg the right in 2a . 2 B shown operating wheel 52 ) to the heating bath 3 turn on and the left, on the control unit 10 outside the display 20 provided push-turn wheel (eg the left in 2a . 2 B shown operating wheel 52 ) are pressed to the rotary drive 9 turn. Preferably, at least two, preferably more than two, different rotational speeds are provided for the push-turn wheel, wherein the rotation of the rotary wheel at the first speed a first Stepping in the input of values causes and rotating the wheel at the second speed causes a second, different from the first step in the input of values. For example, three different rotational speeds (slow, medium, fast) can be provided.

The operation of the rotary drive 9 or the heating bath 3 takes place with reference to the respective set target value, which is shown on the display 20 graphically through the target value display 101 respectively. 111 is shown. The setpoint value display is linked to an application program that controls the rotation 9 or a heating device of the heating bath 3 so controls or regulates that after a certain period of rotation drive 9 essentially with the rotational speed corresponding to the target value (in 7a operated at a rotational speed of 13 rpm) or the heated liquid of the heating bath 3 essentially the temperature corresponding to the target value (in 7a a temperature of 40 ° C). The respective current actual value is shown on the display 20 through the actual value display 102 respectively. 112 displayed, the actual value display is linked to an application program which displays the current rotation speed (13 rpm in 7a ) or bath temperature (22.8 ° C in 7a ) (eg by means of a sensor) and graphically on the display 20 represents.
