Anaerobic culture bag with anaerobic indicator

Abstract

The invention relates to an anaerobic culture bag with an anaerobic indicator, which includes a bag body and an anaerobic indicator, the anaerobic indicator includes a casing, a first piston and an opening device, and the casing has a piston chamber The bag body is provided with a one-way valve, and when the gas pressure in the bag body is greater than the air pressure in the piston chamber, the gas in the bag body flows into the piston chamber through the one-way valve The opening device is arranged on the housing, and is used to connect the mouth of the ampoule bottle containing the anaerobic indicator. When the pressure in the piston chamber is higher than a preset value, the opening device is triggered to Open the mouth of the bottle so that the gas in the piston cavity enters the ampoule. The anaerobic culture bag with anaerobic indicator provided by the present invention allows the gas in the piston cavity to enter the ampoule to realize the function of testing the gas in the anaerobic culture bag, effectively improving the anaerobic culture bag anaerobic Oxygen test efficiency.

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...
