Biosafety Cabinet Class I
Product Details:

• Class I is the most basic biosafety cabinet that provides protection to the environment and the laboratory personnel.
• It doesn’t, however, provide protection to the product as the unsterilized room air is drawn over the work surface.
  
• Class I biosafety cabinets are typically used to either enclose specific equipment like centrifuges or for procedures like aerating cultures that might potentially generate aerosols.
• Biosafety cabinets of this class are either ducted (connected to the building exhaust system) or unducted (recirculating filtered exhaust back into the laboratory).
  
• In the Class I BSC, the room air is drawn in through the opening that also allows the entry of the operator’s arm during work.
• The air inside the cabinet then takes in the aerosol particles that may have been generated and moves it away from the operator towards the HEPA filter.
  
• The air moving out of the cabinet is thus, sterilized via the HEPA filters before its discharge to the environment.
• In this way, the cabinets protect the operator and the environment from the aerosol but not the sample.
