Background

The anaerobic workstation catalyzes hydrogen and oxygen to generate water by utilizing the catalytic condition formed by a palladium catalyst, removes the oxygen in the workstation to form an anaerobic environment, and carries out operation or culture on anaerobic microorganisms in the anaerobic environment, and the conventional anaerobic workstation generally adopts two means in order to achieve an aseptic state: 1, an external circulation laminar flow filter is directly installed to achieve an environment of internal sterile laminar flow gas, and a large amount of air is introduced into the external circulation laminar flow filter, so that the anaerobic environment is damaged, an anaerobic workstation is changed into a super clean bench, and the function of the anaerobic workstation is lost; 2 a small-sized gas filter of a non-laminar flow method is arranged inside, but the bacteriostatic and degerming effect is far inferior to that of a laminar flow filter. Therefore, the existing anaerobic workstation has higher risk of anaerobic microorganism cross contamination, and in order to ensure the absolutely anaerobic condition inside the anaerobic workstation, the internal environment pressure is higher than the surrounding environment, thus causing anaerobic microorganism cross contamination and the leakage of harmful microorganisms for culture or operation.
