A Class II biological safety cabinet (BSC) is a ventilated containment device found in laboratories around the world. BSCs are used in many applications, including cell culture, pharmaceutical, clinical and microbiological work. Due to the critical nature accomplished inside these commonly used laboratory products, BSCs are regulated through rigorous standards and compliance. Engineered controls are built into the design of BSCs providing protection to the operator, product and environment.
Globally, different regions have their own standards applicable to BSCs, and manufacturers build and test to the criteria set out in these standards. The air that is drawn into the class II type B2 biological safety cabinet is drawn in through a HEPA filter and then all of the air is exhausted through another HEPA filter to the outside, as opposed to recirculating into the hood or exhausted back into the lab.
