Guidelines for the Use of Microbial Biosafety Cabinets

Biosafety cabinets are essential safety equipment in laboratories, mainly used to protect laboratory personnel, specimens, and the environment from infectious hazards. It forms a negative pressure state inside the cabinet through directional air flow, preventing aerosol leakage and protecting operators. The outside air is efficiently filtered and enters the safety cabinet to prevent sample contamination; The air inside the cabinet is also efficiently filtered and discharged to protect the environment.

 Classification and Typing
Biosafety cabinets are divided into level one, level two, and level three, and the appropriate level should be selected according to different needs.
The models are divided into A1, A2, B1, and B2, each with different applicable scenarios.

 Usage steps
Turn on the power and start the biosafety cabinet.
Turn on the ultraviolet lamp and irradiate for 30 minutes for disinfection.
After disinfection, turn on the lighting and fan.
Press and hold the glass cabinet door to start the operation.
Work precautions: Do not block the fan, all specimens should be opened in the biosafety cabinet, and do not extend your arms outside the cabinet during operation.
After finishing, wipe the cabinet with alcohol, press and hold the lower glass cabinet door, turn off the inoculation ring electric heater switch and fan, and turn on the ultraviolet lamp again for irradiation.

By following the above steps, the safety of the laboratory can be effectively ensured, avoiding cross contamination and personnel injury.
