The utility model discloses a kind of etch-proof chemical glassware, including lower glass dropper, antifouling water dropper, antifouling dropper, spacing ring, lower Capsule and upper Capsule, the top of the lower glass dropper is provided with middle glass dropper, and the top of antifouling water dropper is provided with glue head cap fixing groove, the inside of the glue head cap fixing groove is fixed with lower Capsule, and the top of lower Capsule is provided with upper Capsule, the bottom of the lower Capsule is provided with antifouling dropper, and the bottom of antifouling dropper is provided with antifouling water dropper.The utility model is a kind of glue head dropper, etch-proof Capsule and glass dropper are provided with relative to traditional glue head dropper, avoid damage of the chemical acid alkali medicament to dropper, the upper Capsule and lower Capsule set simultaneously, while being easy to draw liquid, the phenomenon for occurring flowing backwards pollution glue head is it also avoid, the middle glass dropper and antifouling water dropper of setting so both ensure that liquid was not contaminated, also ensure that glue head is not corroded, and is easy to promoting the use of in teaching and experimentation.
Description
Technical field
The utility model is related to chemical experimental instrument technical field, specially a kind of etch-proof chemical glassware.
Background technology
With the development in epoch, the living standard of people is constantly improved, and chemical experiment is every junior-senior high school, or even higher
Academic Major compulsory course, glue head dropper is used as one of chemical apparatuses initially contacted in all kinds of experimentations
Frequency it is very high, it is easy to use although common glue head dropper makes simple, during concrete operations, due to
The general idea or other reasonses of operating personnel, its internal solution is easy to flow backward in glue head, and solution is polluted, caused
The liquid drawn can not be continuing with, and glue head can not be also continuing with, and common glue head dropper does not possess anticorrosive property,
Often drawn in chemical test with glue head dropper with the stronger medicament of acid and alkali corrosion, conventional nozzle can not meet demand,
Therefore it is badly in need of being improved prior art, to solve the above problems.
Utility model content
The purpose of this utility model is to provide a kind of etch-proof chemical glassware, to solve in above-mentioned background technology
The problem of proposition.
To achieve the above object, the utility model provides following technical scheme：A kind of etch-proof chemical glassware, bag
Lower glass dropper, antifouling water dropper, antifouling dropper, spacing ring, lower Capsule and upper Capsule are included, the top of the lower glass dropper is provided with
Middle glass dropper, and the top of antifouling water dropper is provided with glue head cap fixing groove, the inside of the glue head cap fixing groove is fixed with lower glue
Cap, and the top of lower Capsule is provided with upper Capsule, the bottom of the lower Capsule is provided with antifouling dropper, and the bottom of antifouling dropper is provided with
Antifouling water dropper.
It is preferred that, the outer surface of the middle glass dropper is provided with graduation mark.
It is preferred that, the lower glass dropper, middle glass dropper, the inner side of antifouling dropper are all provided with anticorrosion glassy layer.
It is preferred that, it is provided with spacing ring with lower Capsule junction at the top of the glue head cap fixing groove.
It is preferred that, the madial wall of the lower Capsule and upper Capsule is coated with erosion shield.
Compared with prior art, the beneficial effects of the utility model are：The etch-proof chemical glassware is a kind of glue
Head dropper, relative to traditional glue head dropper is provided with etch-proof Capsule and glass dropper, it is to avoid chemical acid alkali medicament is to drop
The damage of pipe, while the upper Capsule and lower Capsule that set, while being easy to draw liquid, it also avoid occurring flowing backwards pollution glue head
Phenomenon, the middle glass dropper and antifouling water dropper of setting so both ensure that liquid was not contaminated, and also ensure that glue head is not corroded,
It can for a long time reuse, be easy to promoting the use of in teaching and experimentation.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Refer to Fig. 1-2, a kind of embodiment that the utility model is provided：A kind of etch-proof chemical glassware, including
Lower glass dropper 1, antifouling water dropper 3, antifouling dropper 4, spacing ring 6, lower Capsule 7 and upper Capsule 8, the top of lower glass dropper 1 are set
There is middle glass dropper 2, and the top of antifouling water dropper 3 is provided with glue head cap fixing groove 5, antifouling water dropper 3 can avoid the backflow of liquid
The liquid pollution caused, the outer surface of middle glass dropper 2 is provided with graduation mark, and the inside of glue head cap fixing groove 5 is fixed with lower Capsule
7, and the top of lower Capsule 7 is provided with upper Capsule 8, lower Capsule 7 can store liquid, and the top of glue head cap fixing groove 5 connects with lower Capsule 7
Meet place and be provided with spacing ring 6, the bottom of lower Capsule 7 is provided with antifouling dropper 4, and the bottom of antifouling dropper 4 is provided with antifouling water dropper 3, under
Glass dropper 1, middle glass dropper 2, the inner side of antifouling dropper 4 are all provided with anticorrosion glassy layer, lower Capsule 7 and upper Capsule 8
Madial wall is coated with erosion shield.
Specifically used mode：In use, upper Capsule 8 is pinched into the portion gas in extrusion dropper, glass dropper 1 is then descended
