Class II Type B1/B2 Biological Safety Cabinets

In order to protect the researcher from potentially dangerous samples and the samples from contamination, class II type B2 biological safety cabinets are used. The class II type B2 biological safety cabinets are ventilated workstations that are enclosed on three sides, have a positive pressure, and are used in microbiology labs, toxicology labs, and research labs to contain pathogens and toxic chemicals inside the work area while at the same time ensuring the samples, which can include tissue and cell cultures, are not contaminated by the environment outside of the safety hood. 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.

Before buying a class II type B2 biological safety cabinet, consider your needs in regards to size your lab needs and can accommodate and whether it has a system to monitor pressure and exhaust and sound an alarm if things are out of your parameters.
