What is the difference between a biological safety cabinet and a fume hood?

1, fume hoods are also called fume hoods, it is specifically designed for some of the toxic fumes and chemical gases in the experiment, mainly in time to eliminate these toxic fumes and chemical gases, but it can not effectively remove the microbial media, not equipped with HEPA filters, some of the microbial samples placed inside the fume hoods will be dispersed to the outside of the cabinet, contamination of the laboratory environment.

2, biological safety cabinet is for the operation of primary cultures, bacterial strains and diagnostic specimens and other infectious experimental materials, used to protect the staff, the laboratory environment and experimental products, so that it avoids exposure to infectious aerosols and spattering may be generated in the course of the above operations and design.

3, ultra-clean table is ultra-clean workbench by blowing through the work area of the vertical or horizontal laminar flow of air to prevent the test specimen or product by the work area outside of the dust or bacterial contamination, is designed to protect the test specimen or product. However, once the microbial samples are placed in the work area, the laminar air flow will blow the air with microbial media to the front of the staff and create a danger, and need to be very careful when using.

Fume hoods and ultra-clean benches, unlike biosafety cabinets, should not be used in experiments or manufacturing processes involving microbiological materials. Of course, the safety cabinet effective work is the premise of the purchase of qualified safety cabinets and the correct use of safety cabinets.

This is the difference between a fume hood (fume cupboard) and a biosafety cabinet and ultra-clean bench.
