How does biosafety cabinet class 2 works?

A Class II biOSafety cabinet provides a controlled environment for handling biological materials while protecting both the user and the environment. It operates by drawing air into the cabinet through a front opening, creating a barrier that prevents contaminants from escaping. The air is then filtered using HEPA filters before being recirculated within the cabinet and exhausted outside, ensuring that any airborne pathogens are effectively captured and neutralized. This design allows for safe manipulation of infectious agents while maintaining a sterile workspace.
