Biosafety cabinet [biological safety cabinet] has HEPA filter and protects staff and experiment from all external effects harmful to health. Generally used for safe work on materials contaminated with infectious microorganisms (or pathogens). For this reason, Biosafety cabinets are also called microbiological safety cabinets. All the exhaust air that is thrown out of the cabin is HEPA-filtered air and harmful bacteria and viruses are removed from the application.
Class II cabinets are the most used model in biomedical and microbiology laboratories.
