Abstract
The utility model discloses a chemical laboratory gas generator, relating to a generating device of a chemical laboratory gas (especially harmful to environment and human body). A separating funnel with a siamesed ground mouth glass stopper is inserted into a ground mouth flask provided with two bilaterally symmetrical branch pipes (switches are arranged at the middle parts of the two branch pipes). When the chemical laboratory gas generator is used for collecting the gas, the switch of the branch pipe at the left end of the flask is switched off, and the switch of the branch pipe at the right end is switched on for collecting the gas. When a gas collection bottle at the right end collects the gas fully, the switch of the branch pipe at the right end is switched off, and the switch of the branch pipe at the left end is simultaneously switched on for collecting the gas. When the gas collection bottle at the left end collects the gas fully, the switch of the branch pipe at the left end is switched off, the switch of the branch pipe at the right end is simultaneously switched on for collecting the gas, and the gas according with usage can be prepared with repeated operations. With the adoption of the chemical laboratory gas generator, the gas is guaranteed not to escape into the air, and the problems are solved that in the existing chemical laboratory gas generating device (generally adopting a double hole rubber which is plugged with the separating funnel an the gas guide pipe and is inserted into the flask (or a larger test tube)), the switch can not be arranged on a gas guide pipe to control flow of the gas and that when the usage of the gas is more, large amounts of the gas can escape to the air when the gas is collected and the gas collection bottle is replaced to cause pollution on the environment and damage to human body by the harmful gas, etc.
Description
Affiliated technical field
The utility model relates to the generating means of chemical laboratory (especially to environment and human body harmful) gas.
Background technology
At present, the chemical laboratory gas generating unit is substantially: the diplopore rubber stopper that will have a separatory funnel and a wireway is inserted in the flask (or Boiling tube).But gas usage more for a long time during experiment, because the outflow of switch control gas can't be set on wireway, so collecting gas, just have a large amount of gases in the replacing gas bottle process and spill in the air, if pernicious gas will inevitably pollute environment human body is damaged.
Summary of the invention
In order to overcome the defective of existing chemical laboratory gas generating unit, the utility model provides a kind of chemical laboratory gas generator, and the gas of this device in can control generator flows out, and avoids in the gas collection process it being spilt in the air.
The technical scheme that its technical problem that solves the utility model adopts is: the separatory funnel that has the disjunctor ground glass stopper is inserted into left-right symmetry has its middle being provided with in the ground flask of switch of two arms, the disjunctor ground glass stopper of separatory funnel links to each other with the switch bottom of separatory funnel, inside is hollow, the glass tube of separatory funnel therefrom passes, flask is a ground, is provided with switch in the middle of symmetrical two arms.
This chemical laboratory gas generator is when collecting gas, the switch of flask left end arm cuts out, the switch opens of right-hand member arm is collected gas, after the gas bottle gas of right-hand member is received and expired, closes the switch of right-hand member arm, open the switch of left end arm simultaneously and collect gas, after the gas bottle gas of left end is received and expired, close the switch of left end arm, open the switch of right-hand member arm simultaneously and collect gas, repeatable operation just can prepare the gas that meets consumption, can guarantee that again gas does not spill in the air.
The beneficial effects of the utility model are: make things convenient for the collection of gas, the guarantee pernicious gas does not spill in the air environment and human body is caused adverse effect.
