The secret of ability profound understanding the principles of science related to grasp and the Nature is gone in testing.The importance of experiment is given birth in junior-senior high school
That what is embodied in thing, chemistry and physics teaching material is fairly obvious, the experiment that student does it yourself to carry out is related in relevant portion many
Up to twenty or thirty.Do experiment to be accomplished by using reagent, especially liquid reagent, such as copper-bath, sodium hydroxide solution, salt
Acid solution, dilution heat of sulfuric acid, saline solution, distilled water etc..Because the student of a class often compares many, doing once experiment needs
The liquid reagent amount to be consumed is larger, is generally shifted to an earlier date by Experiment teacher and prepares within one day the liquid examination for needing for second day to use in a large number
Agent, and be loaded into in a big glass container, stand in a long queue the unique of glass container that sequentially open when students are tested
One valve beaker is accessed and used.
Although the mode of this distribution liquid reagent conveniently saves trouble, the present inventor has found that presence is permitted by actual observation
Many problems：First some classmates preview and not enough, to experiment are short in understanding, it is not known that oneself is actually needed how many liquid reagents, takes
A large size beaker and take full one glass, cannoing be used up can not reclaim and can only outwell, cause greatly waste.Secondly, experiment
Teacher prepare liquid reagent be according to number of student and total amount that per capita standard consumption calculating draws, will not excess it is a lot, wave
The liquid reagent of the expense reagent for inevitably resulting in someone not enough more and can not do experiment.Finally, existing splendid attire liquid examination
The Large Copacity glass container of agent often only one of which valve and liquid taking port, the student that class does to test is often up to tens up to a hundred
People, the time for accessing reagent often compares concentration, and student's queuing time length is susceptible to fight for, not only access reagent efficiency it is low and
And also there is potential safety hazard.
Utility model content
The purpose of this utility model be solve existing biological, chemical experiment liquid reagent access that efficiency is low, it is big to waste,
Can not quantitatively access etc. not enough, there is provided a kind of new liquid reagent quantitative sampler, the device change less, simple structure,
Cost is relatively low.For achieving the above object, the technical solution of the utility model is as follows.
A kind of biological, chemical experiment liquid reagent quantitative sampling device, including vessel（1）, mozzle（2）, it is living
Plug（3）, liquid storing barrel（5）, valve（6）And base（10）, the mozzle（2）One end communicate with vessel bottom it is another
End communicates with liquid storing barrel following side, liquid storing barrel（5）Inside it is provided with piston（3）, liquid storage bottom of the barrel is provided with liquid taking port（9）And control
Valve（8）, on liquid storage barrel side wall scale is additionally provided with.
In such scheme, the mozzle that communicates with vessel, liquid storing barrel, the quantity of piston are 3-6, are evenly distributed on
Around vessel.An appropriate number of sample tap design is favorably improved efficiency.
In such scheme, the mozzle（2）Downward-sloping setting is easy to liquid to flow, and angle of inclination is 5-15 °.
In such scheme, the liquid storing barrel（5）With mozzle（2）By sealing shroud（7）It is detachable to be connected.This design can
It is convenient for changing, does not affect to be used separately.
In such scheme, also include for the cushion block of fixed piston position（4）, to prevent piston up-down from causing setting
Volume change.
In such scheme, the base（10）Upper surface is provided with the groove matched with vessel bottom, base
Universal wheel is installed on supporting leg and is easy to movement.
This utility model increases mozzle by periphery in existing presser for liquid reagent bottle, and by mozzle and similar injection
The liquid storing barrel sidepiece of device structure is connected, by the way that piston is moved to into the thick quantitative sampling that liquid reagent is realized in corresponding position.Hold
Device body is flexibly connected and is respectively arranged with valve with liquid storing barrel, not only can be used alone but also the outflow for liquid reagent is added
Dual fail-safe.Compared with prior art, this utility model has the advantages that：（1）Setting volume can accurately be released
Liquid reagent, facilitate student sampling tested；（2）Multiple sample taps can be sampled simultaneously, efficiency high；（3）Student's sampling
Amount can in advance be set by counselor, reduced and wasted, and save experimental drug；（4）Simple structure, easy to clean, roller sets
Meter is convenient to be carried and mobile；（5）Vessel and the separable design of liquid storing barrel, both can be used alone.
