Abstract

The utility model relates to a pollution free bromine storage and bromine taking device for chemical teaching experiments in middle schools. A ground glass reagent bottle of 250 ml is used, an assorted hollow ground glass piston is adopted, a long glass guide pipe and a right glass guide pipe with a glass piston and a glass guide pipe with a glass piston are inserted in drilling holes on the top and the side parts of the piston and the corresponding position of an opening of the ground glass reagent bottle, and the right side of the glass guide pipe with the glass piston is provided with a sharp mouth. The glass guide pipe with the sharp mouth and an interface of the glass guide pipe are sealed in a mode of flame burning and are inserted in the ground glass reagent bottle. The other end of the right glass guide pipe provided with the glass piston is sheathed and connected with a rubber pneumatic bag 3. The utility model solves the problems of the prior art that the environment is polluted, and teachers' and students' health is influenced. The utility model can be extensively popularized in the chemical experiments of the middle schools.

Description

Free of contamination storage bromine, get the bromine device

Technical field:

The utility model relates to a kind of high school chemistry teaching and tests the free of contamination storage bromine of usefulness, gets the bromine device.

Background technology:

At present, in middle school chemical experiment, drop bottle storage bromine commonly used, get bromine and carry out chemical experiment, because bromine is volatile toxic gas, in getting the bromine process, is not to carry out in closed system, so bromine gas inevitably evaporate in the atmosphere, easily causes environmental pollution, has a strong impact on teachers and students' health.

The utility model content:

In order to overcome the deficiencies in the prior art, the utility model provides a kind of free of contamination storage bromine, gets the bromine device, it not only can reach convenient storage bromine, get bromine, and whole operation can't cause bromine volatilization in air, thereby reach the purpose of environmental protection, do not influence teachers and students' health, strengthen the enthusiasm of student's learning chemistry.

The technical scheme that the utility model technical solution problem is adopted is: increase by two wireways beyond the Great Wall at vial, two glass pistons, long points are chewed grass tube and air-blowing capsule.When storage during bromine in ventilating system or the band mouth mask from big storage bottle, pour in the ground glass stoppered bottle of opening the grournd glass hollow piston in advance; Two glass pistons are closed at ordinary times, the liquid bromine is in the closed system, when getting bromine, point chewed and stretch in the reagent bottle of containing bromine liquid, open two glass pistons then, with the air-blowing of air-blowing capsule, then the liquid bromine is pressed in the reagent bottle in the bottle, and light again squish capsule is closed two-piston after the liquid bromine blasted reagent bottle in the end a point was chewed.Point is chewed long duct propose, do not have any pollution, ready access upon use, convenient and practical.

The utility model beneficial effect is: because bromine is got in storage is to carry out in ventilation or closed system, so there is not any pollution, does not damage teachers and students' health, but ready access upon use, this apparatus structure is simple, and is safe and reliable, and it also is applicable to store gets other poisonous, volatile and corrosive organic solvent.

Description of drawings:

Fig. 1 is the utility model overall structure schematic diagram.

Among the figure 1, the grass tube chewed of band point, 2, glass piston, 3, rubber pneumatic bag, 4, hollow grournd glass piston, 5, grass tube, 6, the glass reagent bottle of band ground.

The specific embodiment:

In Fig. 1, at first choose 250ml grournd glass reagent bottle 6, choose supporting hollow grournd glass piston 4 then, top at circular hollow grournd glass piston 4, be provided with the right grass tube of long grass tube 5 and band circular glass piston 2 in sidepiece and the circular grournd glass reagent bottle 6 bottleneck relevant position circular holes, the grass tube 1 that the left side band point of band glass piston 2 is chewed, be inserted in the grournd glass reagent bottle 6 after making the interface sealing of grass tube 1 that band point chews and grass tube 5 with the flame calcination again, again will band glass piston 2 the right grass tubes hold in addition be inserted in to be connected with rubber pneumatic bag 3 reaches gastight purpose.

Claims

1, a kind of free of contamination storage bromine, get the bromine device, by the sharp grass tube of chewing (1) of band, glass piston (2), rubber pneumatic bag (3), hollow grournd glass piston (4), grass tube (5), the glass reagent bottle (6) of band ground is formed, it is characterized in that: at the top of circular hollow grournd glass piston (4), be provided with the right grass tube of grass tube (5) and band circular glass piston (2) in sidepiece and circular grournd glass reagent bottle (6) the bottleneck relevant position circular hole, the grass tube (1) that the left side band point of band circular glass piston (2) is chewed, interface sealing back at sharp grass tube of chewing (1) of band and grass tube (5) is put in the grournd glass reagent bottle (6), will be connected with rubber pneumatic bag (3) with other end of glass piston (2) the right grass tube.
