Description
Technical field
The present invention relates to technical field of experiment equipment, and in particular to a kind of biology, chemical experiment liquid reagent quantitative
Sampling device.
Background technology
Biological and chemical is as important basic subject, and students must take action on one's own to participate in reality during study
Being gone in testing could profound understanding and the secret of the relevant the principles of science of grasp and the Nature.The importance of experiment is given birth in junior-senior high school
That is embodied in thing, chemistry and physics teaching material is fairly obvious, involved in relevant portion to student do it yourself carry out experiment it is more
Up to twenty or thirty.Testing just needs to use reagent, especially liquid reagent, such as copper-bath, sodium hydroxide solution, salt
Acid solution, dilution heat of sulfuric acid, saline solution, distilled water etc..Since the student of a class is often relatively more, doing once experiment needs
The liquid reagent amount to be consumed is larger, and usually shifting to an earlier date one day a large amount of liquid for needing for second day to use that prepare by Experiment teacher tries
Agent, and be loaded into a big glass container, stand in a long queue when students are tested and sequentially open the unique of glass container
One valve picks up use with beaker.
Although the mode of this distribution liquid reagent conveniently saves trouble, the present inventor has found to exist by actual observation to be permitted
More problems：First some classmates preview not enough, to experiment be short in understanding, it is not known that oneself be actually needed how many liquid reagent, take
A large size beaker and take full one glass, cannoing be used up can not recycle and can only outwell, and cause great waste.Secondly, experiment
Teacher prepare liquid reagent be according to number of student and standard consumption is calculated per capita total amount, will not excess it is very much, wave
The reagent that the liquid reagent of expense inevitably results in someone is not enough and can not do experiment.Finally, existing splendid attire liquid examination
The large capacity glass container of agent often only has a valve and liquid taking port, and the student that a class does to test is often up to tens up to a hundred
People, the time for picking up reagent often compare concentration, and student's queuing time length is easily fought for, not only pick up reagent efficiency it is low and
And also there are security risk.
The content of the invention
Pick up that efficiency is low, it is big to waste, cannot it is an object of the invention to solving existing biology, chemical experiment with liquid reagent
The deficiencies of quantitatively picking up, there is provided a kind of new liquid reagent quantitative sampler, the device change smaller, simple in structure, cost
It is relatively low.To achieve the above object, technical scheme is as follows.
A kind of biology, chemical experiment liquid reagent quantitative sampling device, including vessel（1）, diversion pipe（2）, it is living
Plug（3）, liquid storing barrel（5）, valve（6）And base（10）, the diversion pipe（2）One end communicated with vessel bottom it is another
End is communicated 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）, scale is additionally provided with liquid storing barrel side wall.
In such scheme, the diversion pipe that is communicated 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 helps to improve efficiency.
In such scheme, the diversion pipe（2）Tilt down setting to flow easy to liquid, angle of inclination is 5-15 °.
In such scheme, the liquid storing barrel（5）With diversion pipe（2）Pass through sealing shroud（7）It is detachable to be connected.This design can
It is convenient for changing, does not influence to be used separately.
In such scheme, the cushion block for fixed piston position is further included（4）, to prevent piston up-down from causing to set
Volume change.
In such scheme, the base（10）Upper surface is provided with the groove to match with vessel bottom, base
Universal wheel is installed easy to remove in support leg.
The present invention on the periphery of existing presser for liquid reagent bottle by increasing diversion pipe, and by diversion pipe and syringe-like knot
The liquid storing barrel sidepiece of structure is connected, by the way that piston is moved to the thick quantitative sampling for realizing liquid reagent in corresponding position.Container sheet
Body is flexibly connected with liquid storing barrel and is respectively arranged with valve, not only can be used alone but also has added double guarantors for the outflow of liquid reagent
Danger.Compared with prior art, the invention has the advantages that：（1）The liquid examination of setting volume can accurately be released
Agent, facilitates student's sampling to be tested；（2）Multiple sample taps can sample at the same time, efficient；（3）The amount of student's sampling can be by referring to
Lead teacher to set in advance, reduce and waste, save experimental drug；（4）Simple in structure, easy to clean, the design of roller is conveniently removed
Fortune and movement；（5）Vessel separates design with liquid storing barrel, both can be used alone.

Embodiment
To make those of ordinary skill in the art fully understand technical scheme and beneficial effect, below in conjunction with attached drawing
It is further described with specific embodiment.It should be noted that following embodiments are only used as the description of the invention, not structure
Into restriction, the improvement made on the premise of present subject matter is not departed from equally is fallen into its protection domain.
As shown in Figure 1, a kind of biology, chemical experiment liquid reagent quantitative sampling device, the main glass for including cylinder
Glass vessel 1, diversion pipe 2, liquid storing barrel 5, piston 3, base 10.It is uniform close to bottom on the downside of 1 periphery of glass container body
3-6 glass diversion pipe 2 is provided with, water conservancy diversion pipe end is connected by sealing shroud 7 with the feed inlet that liquid storing barrel sidepiece extends, and is held
Prepared reagent can be by the diversion pipe that is obliquely installed in device body（5-15 ° of angle of inclination）Smoothly flow into liquid storing barrel.Liquid storage
The structure syringe-like of bucket, is made of hollow glass infuser and piston, corresponding scale is provided with barrel, piston motion
The fluid space that position difference reserves is different.The volume set in order to prevent changes, and pad is additionally provided with piston rod
Block.With reference to the experience actually used before, base is additionally provided with below vessel, the upper surface that base is in contact with it is set
It is fluted, the roller of brake gear is provided with the support leg of base, facilitates the movement and fixation of reagent bottle.
Piston is pushed to the position of setting during use（Such as 100mL）, cushion block, which is placed on below piston rod, prevents its shifting
Dynamic, closing control valve 8 opens valve 6, and prepared liquid reagent enters along diversion pipe and fills up liquid storing barrel in vessel
Headspace, being then switched off the opening valve 8 of valve 6 makes liquid reagent be flowed out from liquid taking port.Each reagent bottle is for 3-6
Group classmate samples at the same time, and efficiency is greatly improved.
