Abstract

The invention discloses an anaerobic workstation with a gas filter, and relates to the field of anaerobic workstations. The anaerobic workstation with the gas filter reduces the risk, and the problem that an existing anaerobic workstation is not provided with a laminar flow internal circulation filter and has higher risks of cross contamination of biological samples and leakage of harmful microorganisms are solved. By arranging a gas filter mechanism, gas in the anaerobic workstation forms sterile laminar gas in a working cabin after passing through the gas filter mechanism, the sterile laminar gas enters a backflow channel through a flow guide hole and is sucked into the gas filter again by a fan to form gas flow internal circulation, the gas flow internal circulation is detected by a sensor, whether oxygen is contained or not is judged by a controller mechanism, if oxygen exists, mixed gas composed of hydrogen and nitrogen is input, the oxygen is removed through the catalytic reaction of the palladium catalyst, an anaerobic and sterile laminar gas environment is formed, the risks of cross contamination between samples and harmful microorganism leakage are reduced, and the anaerobic workstation with the gas filter is mainly used for culture and operation of anaerobic microorganisms.

Description

technical field [0001] The invention relates to the field of anaerobic workstations, in particular to an anaerobic workstation with a gas filter. Background technique [0002] The anaerobic workstation uses the catalytic conditions formed by the palladium catalyst to catalyze hydrogen and oxygen to generate water, remove the oxygen in the workstation to form an anaerobic environment, and operate or cultivate anaerobic microorganisms in an anaerobic environment. The existing anaerobic In order to achieve a sterile state, the workstation generally adopts two methods: 1. Directly install the external circulation laminar flow filter to achieve an internal sterile laminar gas environment, because the external circulation laminar flow filter will introduce a large amount of air, thereby destroying the anaerobic environment. Turn the anaerobic workstation into an ultra-clean bench, and lose the function of the anaerobic workstation; 2. Install a small non-laminar flow gas filter in...
