This ensures that the syringe is not released until the contents are completely or almost completely dispensed.
- the displacement of the Abwerfschiebers in the release position limited to a residual stroke of the receiving body for the delivery of a residual amount of the liquid from the syringe, which is less than a predetermined dosage.
- the pipette has means for automatically overriding the displaceability of the receiving body by means of the actuator at the entrance of the receiving body in the end portion of its displacement range, in which the available residual stroke falls below a predetermined Dosierhub, which is required to deliver a predetermined dosage.
- the automatic override of the actuator the user notices that the predetermined dosage is no longer available. Accidental dosing too small a residual amount is thereby effectively prevented.
- the rest quantity can be given in different ways.
- the receiving body in the end portion of its displacement region by actuation of the elevator member is displaced.
- the user can cause the delivery of the residual amount by targeted actuation of the elevator organ.
- the syringe can be dropped by targeted actuation of the actuator.
- liquid is absorbed by displacement of the elevator organ into the syringe, whereby the receiving body is also moved beyond the end portion.
- the Abwerfschieber be relocated from the release position to the waiting position due to the coupling of the means for displacing the Abwerfschiebers with the piston adjusting devices.
- the guide means and the other guide means are, for example, designed so that they lead the Abwerfschieber, which is arranged with its the trigger levers end facing continuously in the housing-fixed guide, with its other end in a pivoting movement in the range of movement of the actuator.
- the Abwerfschieber is provided with a further driving surface, in the range of movement of a connected to the receiving body, another driver is arranged to take the Abwerfschieber in the displacement of the receiving body from the receptacle away in the waiting position, wherein the further driver is disengaged from the further driving surface when the ejection slider reaches the waiting position.
- the driving surface and the further driving surface are arranged on mutually facing sides of the struts.
- the further driving surface and the further driver on ramp elements and / or cam elements of the Abwerfschiebers and the receiving body engage each other as the ejector slides into the firing position. They separate from each other when the ejector moves into the waiting position.
- At least one ramp element and / or cam element of the Abwerfschiebers is arranged on a strut.
- This ramp element is formed for example by a cam with a ramp-like flank.
- the actuator can actuate the Abwerfschieber directly or indirectly.
- the actuating member is connected to a diaphragm whose end face is associated with one end of the Abwerfschiebers to push the Abwerfschieber from the release position against the release lever.
- the diaphragm can serve the cover of a housing opening, through which the actuator is led out of the pipette housing to the outside.
- a sprung abutment 8 is arranged, against which the upper side of the syringe flange 4 can be pressed.
- the abutment 8 has sensors 8.1. for scanning a coding at the top of the syringe flange 4.
- the syringe gripping levers 14 are arranged with a gripping arm 17 below the pivot axes 15.
- An actuating arm 18 of the syringe gripping lever 14 is located above the pivot axes 15th
- torsion springs are arranged, which bias the piston gripping lever 22 in the direction of a position in which they attack the piston collar 23.
- the outer side of the actuating arm of the piston gripper lever 22 is shaped so that they are in this locking position in the pivoting range of Entriegelungsnocken on the inside of the syringe gripping lever 14.
- the correct alignment of the piston gripper lever 22 on the syringe gripping lever 14 is ensured by the guidance of an elevator member 24 in an axial slot 25 of the pipette housing 2 ( Fig. 1 ).
- the release levers 26 are connected to the upper ends of the actuating arms 18 and inclined at an acute angle to the axis of the syringe plunger 11.
- the piston adjusting devices 28 include a threaded spindle 31 (alternatively a rack), which is also firmly connected to the receiving body 9.
- a threaded spindle 31 (alternatively a rack), which is also firmly connected to the receiving body 9.
- a cover sleeve 32 On the threaded spindle 31 is seated a cover sleeve 32 whose axial position on the threaded spindle 31 by means of a rotary knob 33 is adjustable.
- the knob 33 has a guide cam, not shown, which cooperates with a fixedly connected to the threaded spindle 31 guide pin 34.
- the strut 47 has on top two cams 50, each having a ramp at the top.
- the housing 30 connected to the receiving body 9 is provided with a tongue 51 which extends parallel to the piston receptacle ( Fig. 5 ).
- the tongue 30 has at the bottom recesses 52 which are complementary to the cam 50 formed on the strut 47.
- the cams 50 can engage in the recesses 52.
- the dosing amount is set by means of the knob 33.
- a syringe 5 is used.
- the receiving body 9 is displaced as far as possible for receiving 3 out.
- a syringe 5 is inserted in advance with the upper end of the syringe plunger 11 and the syringe flange 4 through the axial opening 6 in the receptacle 3.
- the upper end of the syringe plunger 11 immersed in the piston seat 10 of the receiving body 9 and the syringe flange 4 is pressed against the sprung abutment 8.
- the syringe gripping lever 14 and piston gripping lever 22 are pressed against the spring action to the outside and then snap due to the spring action with their gripping ends behind the syringe flange 4 and the piston collar 23. Thereafter, the syringe 5 is fixed in the receptacles 3, 10.
- Liquid can be absorbed into the syringe 5 by displacing the elevator member 24 upwards. By means of the rotary knob 33, a dosage is set. By pressing the actuator 35, the syringe plunger 11 is down moved and delivered the desired amount of liquid. When the syringe 5 is almost deflated, so that only a residual amount is located therein, the leaf spring 42 keeps the pawl 41 from falling into the threaded spindle 31 from. The user can then deliver by pushing the elevator member 24 down the remaining amount. In this case, the driver 30 pushes the Abwerfschieber 44 so that the ramps 53 run over the cam and lift the upper end of Abwerfschiebers 44 ( Fig. 8 ).
- the syringe 5 can be emptied by a single or multiple actuation of the actuator 35, wherein the aperture 40 does not come into contact with the upper end of Abwerfschiebers 44, since this is not in the range of movement of the aperture 40. Only after delivery of the remaining amount, the syringe 5 can be solved in the manner described by the pipette 1.
- the driver 30 displaces the Abwerfschieber 44, so that the ramps 53 run over the cam and the upper end of the Abwerfschiebers 44 enters the range of movement of the aperture 40.
- the Abwerfschieber 44 can create resiliently against the inside of the aperture 40.
- the upper end of the Abwerfschiebers 44 enter the range of movement of the aperture 40. Possibly. this is supported by pivoting the lever arm 54 upwards, so that the control cam 57 hits against the threaded spindle 31 facing side of the Abwerfschiebers 44 supported. Further actuation of the actuating button 35 causes a displacement of the Abwerfschiebers 44, so that the release lever 26 are actuated and syringe 5 is dropped.
- liquid can be dispensed in the manner already described and the syringe 5 can be discarded.
