Half row super clean 100 level protection Class II B2 Biosafety
Cabinet
Class II B2 Biosafety Cabinet Features:
1. The LCD screen displays the measurement parameters;
2. Wind speed sensor and temperature sensor, sensitive and
accurate;
3. Audiovisual alarm;
4. There is negative pressure around the working area, which can
ensure the maximum safety of the working area;
5. Lean forward 10°, which can provide the operator with a sense of
comfort when working for a long time, reduce glare and extend into
the work area to the greatest extent;
6. With power-off memory function;
7. Explosion-proof, anti-fall, anti-ultraviolet electric tempered
glass front window;
8. Interlocking function: ultraviolet light and front window.
Class II B2 Biosafety Cabinet role is to protect the operator, lab
environment and test materials, when the operator in primitive
cultures, bacteria strains or experiment with infectious materials
used, to avoid contact with infectious aerosols or light out.
Biological safety cabinet is microbiology, biomedicine, gene
recombination, animal experiment and necessary biological products
such as laboratory equipment, especially the operator need to take
protective measures, such as health care, pharmaceutical,
scientific research for bacterial culture provides the asepsis
dustless safe work environment.

Maintenance of Class II B2 Biosafety Cabinet:
In order to ensure the safety of the biological safety cabinet, the
safety cabinet should be maintained and maintained regularly:
1. The working area of the safety cabinet should be cleaned and
disinfected before and after each use.
2. After the service life of the HEPA filter expires, it should be
replaced by a professional who has received special training in
biological safety cabinets.
3. The laboratory biosafety manual promulgated by WHO, the U.S.
biosafety cabinet standard NSF49 and the China Food and Drug
Administration biosafety cabinet standard YY0569 all require one of
the following conditions, the biosafety cabinet should be safety
tested: installation is completed and put into use Before; annual
routine inspection; when the safety cabinet is shifted; after
replacing the HEPA filter and repairing internal components.
Safety inspection includes the following aspects:
1. Inlet flow direction and wind speed detection: Inlet flow
direction is detected on the working section by smoke method or
wire method. The detection position includes the periphery and
middle area of the working window; the wind speed of the intake
flow is measured by an anemometer.
2. Detecting the wind speed and uniformity of the sinking airflow:
Use an anemometer to measure the wind speed of the cross section
evenly.
3. Work area cleanliness detection: use dust particle timer to
detect in the work area.
4. Noise detection: The horizontal center of the front panel of the
biological safety cabinet is 300mm outwards and 380mm above the
work surface to measure the noise with the sound level.
5. Illumination detection: set a measuring point every 30cm along
the center line of the length of the worktable.
6. Leakage detection of the cabinet: Seal the safety cabinet and
pressurize it to 500Pa. After 30 minutes, connect a pressure gauge
or pressure sensor system in the test area to detect with the
pressure decay method, or detect with the soap bubble method.
