Audited Supplier Ventilation cabinet (fume hood) is an important part of the laboratory equipment, it is a kind of effective local ventilation. Ventilation cabinet can make experiment operator and laboratory other workers away from the toxic gases, chemical reagents in the laboratory environment infringement, in ensuring the safety of the lab environment and overall functional play a vital role.
A fume hood is typically a large piece of equipment enclosing five sides of a work area, the bottom of which is most commonly located at a standing work height.Two main types exist, ducted and recirculating (ductless). The principle is the same for both types: air is drawn in from the front (open) side of the cabinet, and either expelled outside the building or made safe through filtration and fed back into the room. This is used to:
*Protect the user from inhaling toxic gases (fume hoods, biosafety cabinets, glove boxes)
*Protect the product or experiment (biosafety cabinets, glove boxes)
*Protect the environment (recirculating fume hoods, certain biosafety cabinets, and any other type when fitted with appropriate filters in the exhaust airstream)
