Class II B2 Biosafety Cabinet Half Row Super Clean

Product Specification

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.
