Biosafety cabinet working principle

biological safety cabinet (BSC) is the primary means of containment developed for working safely with infectious microorganisms.
Class II BSCs, the most common cabinets used in laboratories, are designed to provide personnel protection (for you and those around you), product protection (for your samples), and environmental protection.

The biosafety cabinet is the basic safety protection equipment in the first-level protective barrier of laboratory biosafety.
The biosafety cabinet working principle is mainly to suck the air in the biological safety cabinet outward to keep the biosafety cabinet in a negative pressure state, and to protect the staff through vertical airflow.

Class I biosafety cabinets protect workers and the environment without protecting samples.
The airflow principle is the same as that of the laboratory general kitchen.
The difference is that the exhaust port is equipped with a filter.
All types of biosafety cabinets use filters on the exhaust and air inlets.
