Class II: B2 Biological Safety Cabinet ensures the user, product and environment protection from the biohazard factor and prevents cross-contamination of various samples used in experiments. The type B2 total exhaust cabinets are widely used in toxicology laboratories and similar applications where chemical effluent is present and clean air is essential.

The air goes through a HEPA filter and is 100% exhausted through a dedicated duct with an exhaust fan motor. The air is then released into the atmosphere.
