Biological safety cabinet is a kind of safety equipment widely used in scientific research, teaching, clinical inspection and production in the fields of microbiology, biomedicine, genetic recombination, animal experimentation, biological products, etc. It is also a first-level protective barrier in laboratory biosafety The most basic safety protection equipment.
The biological safety cabinet is a negative pressure purification workbench. The correct operation of the biological safety cabinet can completely protect the staff, the tested samples and prevent the occurrence of cross-contamination; while the ultra-clean workbench only protects the operating object but not the staff. And the clean bench of the laboratory environment. Therefore, in the scientific research, teaching, clinical testing and production of microbiology and biomedicine, biological safety cabinets should be selected and used instead of ultra-clean workbenches.
The Clean Benches are designed to protect the experimental materials. The air is sucked into the pre-filter through the fan, and filtered through the static pressure box into the high-efficiency filter, and the filtered air is sent out in a vertical or horizontal airflow state. Make the operation area reach a hundred grades of cleanliness, and ensure the environmental cleanliness requirements of production.
Only the sample can be protected, not the operator.
From the perspective of cleanliness level, biological safety cabinets are also more advanced than ultra-clean workbenches.
The advantages of the ultra-clean workbench are easy operation, relatively comfortable, high work efficiency, short preparation time, can be operated for more than 10 minutes after booting, and can basically be used at any time.
