LCD Display Class Ii Type A2 Biosafety Cabinet ISO 5 Calss HEPA Filter
Class Ii Type A2 Biosafety Cabinet The Main Advantage:
1. Motorized front window.
2. Time reserve function.
3. HEPA filter life and UV life indicator.
4. Automatic air speed adjustable with filter block.
5. After the front window is completely lowered, it will be
automatically sealed on the gasket around the closed chamber to
isolate the inside and prevent pollutants from escaping during the
purification process.
6. If a power failure occurs, the front window can be closed
manually.

Maintenance of Class Ii Type A2 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 tested for safety: the 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. Downstream wind speed and uniformity detection: Use anemometers to evenly arrange points to measure cross-sectional wind speed.
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 attenuation method, or detect with the soap bubble method.
