Class II A2 Biosafety Cabinets Features:
◆ Soft touch control panel, LCD display.
◆ UV lamp sterilization.
◆ Stable air flow system; provide firm protection for people and
the environment.
◆ Energy saving, high efficiency and low noise.
◆ The working area is made of standard 304 stainless steel, and the
internal arc angle is designed without clean dead corners.
◆ Adopt German imported fan, with low noise and large air volume.
◆ Using a unique high-efficiency filter, the working area reaches
100 levels, and the filtration efficiency is >99.995%.

Maintenance of Class II A2 Biosafety Cabinets:
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.
