The working principle of BSC Biosafety Cabinet:
The working principle of the biological safety cabinet is mainly to suck the air inside the cabinet to maintain a negative pressure in the cabinet, and protect the staff through the vertical airflow; the outside air is filtered by a high-efficiency particulate air filter (HEPA) After filtering, enter the safety cabinet to avoid contamination of the processed samples; the air in the cabinet also needs to be filtered by a HEPA filter before being discharged into the atmosphere to protect the environment.
Classification of BSC Biosafety Cabinet:
According to the NSF49 standard, the medium of biosafety level 1 (P1) refers to ordinary harmless bacteria, viruses and other microorganisms; the medium of biosafety level 2 (P2) refers to general pathogenic bacteria, viruses and other microorganisms; biosafety The medium of level 3 (P3) refers to microorganisms such as potent/fatal bacteria and viruses, but can be cured after infection; the medium of biosafety level 4 (P4) refers to microorganisms such as potent/fatal bacteria, viruses, etc., which are not easy to cure after infection . This standard divides biological safety cabinets into levels I, II, and III, which can be applied to the operation of media with different levels of biological safety.
