Description

technical field [0001] The invention relates to a biological safety device, in particular to a three-level biological safety cabinet. Background technique [0002] The biological safety cabinet is a biological safety device. The test sample is confined in the device through the biological seal of the system, and the polluted air in the device is filtered and purified, and then discharged, so that the operator and the test sample can be isolated and effectively protected. The environment is free from pollution. The sample operation space in the device prevents cross-contamination of test samples through one-way flow of filtered air. However, the existing biological safety cabinets have low filtration efficiency and unstable working performance. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a three-level biological safety cabinet with high filtration efficiency and stable working performance. [0004] The pres...
