Biological safety cabinet instructions

2021-03-13

Biosafety cabinets can be divided into three categories: primary, secondary and tertiary to meet different biological research and epidemic prevention requirements.

Biological Safety Cabinet operating specifications:

Turn on the self-cleaning before use, and turn on the UV sterilization lamp to ensure that the work area is free of pollution and reaches the 100-level state.

The front window should be closed during sterilization.

When working, the front window opening height should be less than 200mm, and the air pressure in the area is normal.

The work surface is 304 stainless steel. When there are pollutants, it should be cleaned with alcohol in time to ensure the service life of the work surface.

Care should be taken not to subject the device to strong vibrations when opening the front window to maintain the integrity of the flat glass.

Biological safety cabinet cleaning and disinfection instructions:

1. Since the remaining medium may cause microbial growth and reproduction, at the end of the experiment, all items in the Biosafety Cabinet, including the instrument and equipment, should be cleaned of surface contamination and removed from the safety cabinet.

2. Remove the contamination of the inner surface of the biosafety cabinet before and after each use. The work surface and the inner wall should be wiped with a disinfectant, and the disinfectant used should be able to kill any microorganisms that may be found in the safety cabinet. At the end of each day's experiment, the surface of the biosafety cabinet, the surrounding area, and the inside and outside of the glass should be wiped to remove surface contamination. When effective against the target organism, it can be disinfected with a bleach solution or 70% alcohol. After using a corrosive disinfectant such as bleach, it must be wiped again with sterile water.
