The utility model has the characteristics of the measurement is accurate, easy operation, swift, can be used to move in a large number the experimental study of getting quantitative solution, pipette through different specifications alright satisfy corresponding experiment requirement, very big improvement move the accuracy and the operating efficiency of liquid.
Description
Technical field
The utility model relates to pipette; Specifically fast quantification liquid-transfering device.
Background technology
Pipette is a kind of measuring device of the solution being used for accurately pipetting certain volume.It is a slender glass tube, and its lower end is sharp mouth shape, and a graticule is carved with at neck place, upper end, is the graticule of pipetted exact volume, in use, inserts ear washing bulb, suck a certain amount of liquid by the suction of ear washing bulb in the upper port of pipette.In Conventional pipettes operating process, human factor impact is larger, sometimes needs repeatedly to measure, accurately could measure volumetric soiutions, therefore, just can not meet move liquid requirement when relating to a large amount of pipetting.We have invented a kind of new fast quantification liquid-transfering device for this reason, solve above technical problem.
Utility model content
The purpose of this utility model is to provide fast quantification liquid-transfering device, there is accurate measurement, simple to operate, feature efficiently, can be used for the experimental study pipetting volumetric soiutions in a large number, just corresponding requirement of experiment be can meet by the pipette of different size, the accuracy and operating efficiency of moving liquid greatly improved.
In order to reach above-mentioned purpose, the utility model have employed following technical scheme, fast quantification liquid-transfering device, comprise quantitative pipette, push type plastic bottle, be communicated with by anticorrosion rubber hose between described quantitative pipette and push type plastic bottle, described quantitative pipette tip has a bulging part slightly thicker than pipette, and a little perforate is arranged at the top of bulging part; One built-in curved mouth is arranged at the bottom of bulging part, this curved mouth lower limb with quantitatively move liquid graduation mark and overlap, described anticorrosion rubber hose upper end is connected with described curved mouth.
Described quantitative pipette lower end becomes sharp mouth shape, and there is built-in glass piston Jian Zui upper end; Quantitatively measure by opening, closing glass piston and release a certain amount of liquid.
The built-in plastic tube of described push type plastic bottle, is connected with anticorrosion rubber hose lower end after plastic tube upper end passes bottle stopper.
Described quantitative pipette is fixed on iron stand.
Described iron stand is arranged the iron clamp that can move up and down location, quantitative pipette is fixed by the iron clamp on iron stand.
Compared to prior art, the utility model has following beneficial effect:
Pipette in the utility model and traditional pipette have very large difference, this pipette accurately measures volumetric soiutions by the curved mouth in top, control into discharge opeing by lower piston, and control drain age velocity by the aperture of piston, greatly improve the speeds control degree of accuracy and the discharge opeing measuring solution.
Accompanying drawing explanation
Fig. 1 is the structural representation of fast quantification liquid-transfering device of the present utility model.
In figure: iron stand 1, iron clamp 2, quantitatively pipette 3, built-in glass piston 4, built-in curved mouth 5, anticorrosion rubber hose 6, built-in plastic tube 7, push type plastic bottle 8.
Detailed description of the invention
Relevant detailed description of the present utility model and technology contents, coordinate accompanying drawing to be described as follows, but accompanying drawing only provides with reference to the use with explanation, is not used for being limited the utility model.
According to Fig. 1, fast quantification liquid-transfering device, comprise quantitative pipette 3, push type plastic bottle 8, be communicated with by anticorrosion rubber hose 6 between described quantitative pipette and push type plastic bottle, described quantitative pipette tip has a bulging part slightly thicker than pipette, and a little perforate is arranged at the top of bulging part; One built-in curved mouth 5 is arranged at the bottom of bulging part, this curved mouth lower limb with quantitatively move liquid graduation mark and overlap, described anticorrosion rubber hose upper end is connected with described curved mouth.Described quantitative pipette lower end becomes sharp mouth shape, and there is built-in glass piston 4 Jian Zui upper end; The built-in plastic tube 7 of described push type plastic bottle, is connected with anticorrosion rubber hose lower end after plastic tube upper end passes bottle stopper.Described quantitative pipette is fixed on iron stand 1.Described iron stand is arranged the iron clamp 2 that can move up and down location, quantitative pipette is fixed by the iron clamp on iron stand.
Built-in glass piston is arranged at the bottom of the quantitative pipette improved, and built-in glass bend-head is arranged at top, and meanwhile, its top is the bulging part slightly thicker than pipette normal portions, has individual aperture in the middle of the top of bulging part.The built-in glass piston of the quantitative pipette improved can be good at the eliminating speed controlling solution.The top glass elbow of quantitative pipette improved, it overlaps with quantity tube graduation mark very cleverly, and solution that can be excessive in resorption pipette, makes the precision quantitatively measuring solution greatly improve.The top bulging part of the quantitative pipette improved, effectively can prevent from clamp-oning too much solution and overflowing pipette, cause the waste of solution.The top aperture of top bulging part of the quantitative pipette improved, can meet into being communicated with the demand be convenient to into, discharge opeing during, discharge opeing with air, can well prevent solution from too much contacting with air again.Solution can be got into pipette by pressing by push type plastic bottle, the plastics pressure of the inside of a bottle of distortion and the relation of atm difference can be relied on simultaneously, solution unnecessary in pipette is sucked back plastic bottle automatically.
First pipette 3 is vertically fixed on iron stand 1 by iron clamp 2 moving in liquid process, only have pipette 3 to be in plumbness, guarantee measures the precision of solution; Then by rubber tube 6, one end connects the top elbow 5 of pipette 3, and one end connects the built-in plastic tube 7 that can press plastic bottle 8.After connecting device, the solution that will measure is poured in push type plastic bottle 8, and is tightened by bottle cap, then close glass piston 4, by pressing plastic bottle 8, the solution in plastic bottle 8 is by built-in flexible pipe 7, via rubber hose 6, enter in pipette 3 by built-in glass bend-head 5; Moving in liquid process, the solution clamp-oning pipette must exceed the bottom of built-in elbow 5, too much liquid is by the resorption power of the plastic bottle 8 by pressing, return in plastic bottle 8 by built-in glass bend-head 5 resorption, the solution clamp-oned to be prevented simultaneously too much, overflowed by the aperture on glass tube top and cause waste.The built-in glass bend-head of pipette with quantitatively move liquidus and to overlap the precision (0.01ml) that ensure that and quantitatively move liquid; After having measured quantitative liquid, by opening the built-in glass piston 4 on pipette 3, just volumetric soiutions can be discharged, in addition, by the rate of outflow of the aperture that regulates the built-in glass piston 4 on pipette 3 also controllable liquid.
The utility model can be used for the experimental study pipetting volumetric soiutions in a large number, just can meet corresponding requirement of experiment by the pipette of different size, greatly improves the accuracy and operating efficiency of moving liquid.
The foregoing is only preferred embodiment of the present utility model, be not used to limit the scope of the claims of the present utility model, other use the equivalence of patent spirit of the present utility model to change, and all should all belong to the scope of the claims of the present utility model.
