Class II B2 Biological Safety Cabinet Biosafety Cabinet

Working principle of class II B2 biological safety cabinet biosafety cabinet The working principle of the biological safety cabinet is mainly to draw the air in the cabinet outward to keep the negative pressure in the cabinet and protect the workers by vertical airflow; the outside air is filtered by a high-efficiency particulate air filter (HEPA) Filter) into the safety cabinet to avoid contamination of the processed samples; the air in the cabinet also needs to be filtered through the HEPA filter before being discharged into the atmosphere to protect the environment.
