What are the basic differences between laminar air flow and biosafety hood?


Do you know the difference between a laminar flow hood and a biological safety cabinet?

 

Laminar Flow Hoods

 

  • provide product protection only and must not be used when working with any form of biohazard or chemical hazard
  • any potentially infectious aerosol that is created will lead to exposure of the operator and the environment
  • horizontal-flow clean-air bench used for cell cultures can expose the researcher to aerosols of allergenic or infectious materials.
  • vertical-flow clean-air bench also blows air out into the room

 

Biological Safety Cabinets

 

  • provide personnel and environmental protection and commonly product protection
  • infectious agents must be used in a biological safety cabinet NOT a laminar flow hood
