Abstract
The invention belongs to the field of heating in laboratories and in particular discloses a floating plate in a water bath. The floating plate in the water bath comprises a floating plate body and a plate cover, wherein plate holes are formed in the floating plate body; and the floating plate body is covered by the plate cover. The floating plate has the effect of solving the technical problem that steam water drops fall on sample containers, so that the probability of sample pollution can be reduced.
Description
Technical field
The present invention relates to laboratory heating art, be specifically related to a kind of water-bath kickboard.
Background technology
Water-bath is mainly used in distilling in laboratory, dry, concentrated, and warm stain chemicals or biological products, also can be used for heated at constant temperature and other humid test, be food, biology, aquatic products, environmental protection, medicine, etc. the indispensable instrument in laboratory, field.Thermostat water bath (ThermostatWaterBath) interior horizontal positioned stainless steel tubular heater, the inside of tank is placed with aluminum shelf with holes.On cover the combination lasso being furnished with different bore, the flask of different bore can be adapted to.Having adjutage on the left of water-bath, is electric box on the right side of thermostat water bath, electric box front panel is equipped with temperature control instrument, power switch.Electrothermal tube and sensor is had in electric box.Its operation principle is sensor is resistance value by the temperature transition of water trough inner water, through integrated amplifier amplification, relatively after, export control signal, effectively control the average heating power of electric heating tube, make water in tank keep constant temperature.When being required to be heated evenly by the object heated, when temperature is no more than 100 DEG C, heating water bath can be used.Water-bath is done with copper or aluminum usually, and lid comprises the circle of multiple overlap, is suitable for the vessel placing different size.
In practical operation, when Eppendorf pipe needs heating water bath, be generally first inserted in the plate hole of the kickboard that foam or plastics are made by Eppendorf pipe, be then placed in water-bath by kickboard, such Eppendorf pipe would not sink to the bottom of a pan, its underpart is heated in water, top is overlapped by kickboard, higher than liquid level, to a certain extent, avoid the moisture in water-bath to enter in Eppendorf pipe, avoid managing interior sample contaminated.
But the lower lid surface of water-bath understands the little liquid pearl that the much steam of aggegation is liquefied as usually, and these little liquid pearls, along with the increase of volume, can drop on Eppendorf pipe, which increase by the contaminated probability of sample heated.At present also there is no special dropping for the globule and the water-bath kickboard that designs.
Summary of the invention
The object of the present invention is to provide a kind of water-bath kickboard, to drop the technical problem on shuttle to solve the steam globule.
For achieving the above object, base case of the present invention is: water-bath kickboard, comprises kickboard body and Ban Gai, and kickboard body is provided with plate hole; Plate lid covers on kickboard body.
Operation principle and the advantage of this programme are: after Eppendorf pipe inserts plate hole, the lower end of pipe is immersed in underwater, and the top of pipe is on the water surface, and the mouth of pipe can not contact the water in water-bath; Plate covers at water-bath inner, and plate lid does not communicate with the external world, so steam can not be made to condense; The lid of water-bath communicates with the external world, so the steam touching water-bath lid can condense into the globule; Plate lid covers on kickboard body, and the globule dropped from lid would not drop on kickboard body, and the Eppendorf pipe be so inserted in plate hole would not be polluted by the globule.
Preferred version one: based on the preferred version of scheme, kickboard body is provided with strut, and plate covers and is provided with bar cover, and strut and bar cover are slidably connected.Prop up plate lid with strut, Eppendorf pipe directly contacts with steam, and heat exchanger effectiveness is high.
Preferred version two: the preferably preferred version of: plate lid is arc surfaced.Be convenient to drop on the globule that plate covers like this be rolled down.
Preferred version three: the preferably preferred version of two: plate is covered with spiral helicine groove, groove one end is connected with plate caping end, the other end is connected with Ban Gai edge.Such globule can collect in a groove, then drips with water at a place at Ban Gai edge, reduces contamination probability.
Preferred version four: the preferably preferred version of three: the cross section of groove is V-arrangement.。The floor space of such groove is less, and droplet is not easily deposited in plate and covers.
Accompanying drawing explanation
Fig. 1 is the structural representation of water-bath kickboard embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: kickboard body 10, strut 11, plate lid 20, bar cover 21, groove 22, EP pipe 30.
Embodiment is substantially as shown in Figure 1:
Water-bath kickboard, comprise the plate lid 20 of kickboard body 10 and arc surfaced, kickboard body 10 is provided with plate hole; Plate lid 20 covers on kickboard body 10; Kickboard body 10 is provided with strut 11, and plate lid 20 is provided with bar cover 21, and strut 11 and bar overlap 21 and be slidably connected; Plate lid 20 is provided with spiral helicine groove 22, and the cross section of groove is V-shaped.Groove 22 one end is connected with plate lid 20 top, the other end is connected with plate lid 20 edge.
To heat Eppendorf pipe (hereinafter referred to as EP pipe 30), EP pipe 30 is inserted in the plate hole of kickboard body 10, cover plate lid 20, then water-bath kickboard is placed in water-bath, water-bath kickboard swims on liquid level, when the globule of the lower lid surface aggegation of water-bath drops, drop on plate lid 20, owing to there is difference in height in plate lid 20, so under gravity, the globule can be slipped in groove 22 nearby, then along the landing of spiral helicine groove 22, drip in the junction of groove 22 with plate lid 20 edge, in can not drop on EP pipe 30.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
