What you did not know about a biosafety cabinet?
Class I Biosafety Cabinets provide personnel and environmental protection inside the laboratory. They have the most basic and rudimentary design among all of the biological safety cabinetry that is available in the market. The way they work is when a stream of inward air moves into the cabinet with aerosols during microbiological manipulations, then passes through a filtration system trapping all airborne particles and contaminants.
