Anaerobic culture bag with anaerobic indicating agent

Abstract

The invention relates to an anaerobic culture bag with an anaerobic indicating agent. The anaerobic culture bag comprises a bag body, and further comprises an anaerobic indicator, the anaerobic indicator comprises a shell, a first piston and a starting device, and the shell is provided with a piston chamber; the bag body is provided with a one-way valve, and a gas in the bag body flows into the piston chamber through the one-way valve when the pressure of the gas in the bag body is greater than the pressure in the piston chamber; and the starting device is arranged on the shell, and is used for connecting a bottle mouth of an ampoule containing the anaerobic indicating agent, and the starting device is triggered when the pressure in the piston chamber is greater than a preset value in order to make the gas in the piston chamber enter the ampoule. The anaerobic culture bag with the anaerobic indicating agent makes the gas in the piston chamber enter the ampoule to realize the testing ofthe gas in the anaerobic culture bag, so the anaerobic testing efficiency of the anaerobic culture bag is effectively improved.

Description

technical field [0001] The invention belongs to the field of containers, in particular to an anaerobic culture bag with an anaerobic indicator. Background technique [0002] The cultivation of anaerobic bacteria not only requires the culture gas environment to be anaerobic, but also requires that the medium does not form peroxides that are harmful to anaerobic bacteria. During the production and storage of the medium, an anaerobic environment and suitable humidity should be maintained. At present, the prepared anaerobic medium is packaged and stored in air-permeable and water-permeable materials. When the air humidity is too high, water seeps in, the humidity of the culture gene is too high, and mold grows and becomes invalid; when the air humidity is too low, the water is lost, and the culture gene is too dry to fail; moreover, due to the infiltration of oxygen, the time is long, the oxygen cultivation The base forms peroxides that are harmful to anaerobic bacteria and mak...
