‌Biosafety Cabinet (BSC)‌
A biosafety cabinet is a critical laboratory equipment designed to protect operators, experimental samples, and the environment from hazardous biological agents. Classified as a Class III medical device, it utilizes a negative-pressure air purification system and HEPA filtration to prevent the spread of harmful microbial aerosols generated during experiments.

‌Core Functions‌

The biosafety cabinet provides ‌three layers of protection‌:

1. ‌Operator Protection‌: HEPA filters capture 99.99% of bacteria and viruses, preventing aerosol leakage.
2. ‌Sample Protection‌: A vertical laminar airflow barrier maintains sterility by blocking external contaminants.
3. ‌Environmental Protection‌: Negative pressure ensures unidirectional airflow, containing hazardous materials within the cabinet.

‌Operational Guidelines‌

• ‌Startup‌: Power on, activate lighting and fan, then raise the sash to the marked line after the indicator turns yellow.
• ‌Procedures‌: Minimize items inside to avoid disrupting airflow; move arms slowly and wait for airflow stabilization.
• ‌Prohibitions‌: Open flames (e.g., alcohol burners) are strictly prohibited—use infrared sterilizers instead.
• ‌Maintenance‌: Disinfect surfaces with 75% ethanol before/after use; replace filters regularly and monitor airflow velocity.

‌Key Difference from Laminar Flow Hood‌

Biosafety cabinets protect ‌personnel, samples, and the environment‌, while laminar flow hoods ‌only protect samples‌ (not operators). Therefore, biosafety cabinets are mandatory for handling infectious materials.
