Biological Safety Cabinet
Biological safety cabinets are used to provide primary containment in the laboratory when the
investigator is using potentially infectious materials. There are three types of biological safety
cabinets:
Class I: The Class I biological safety cabinet is an open-front negative pressure cabinet. The Class
I biological safety cabinet will provide personnel and environmental protection, but not product
protection.
Class II: The Class II biological safety cabinet is an open-front, ventilated cabinet. The Class II
biological safety cabinet will provide personnel, environment and product protection.
Class III: The Class III cabinet is a totally enclosed ventilated cabinet of gas-tight construction.
Operations within the Class III cabinet are conducted through attached rubber gloves. The Class III
biological safety cabinet will provide personnel, environment and product protection. Class III
cabinets can be used to operate infectious agents (usually Classes 3, 4 or 5) .
Advantage
○1 Remote control. The operator need not to contact the biological safety cabinet directly, it’s favorable for preventing cross contamination. It also makes the control operation much easier and convenient. ○2 Foot Switch. Within the range of the activity, we could use foot switch to adjust the height of the front panel. It is our unique design.
○3 Work area surrounded by negative pressure. ○4 Timer function ○5 VFD display ○6 Filter life inquiry
According to the performance criteria:
○1 US Standard ANSI/NSF49:2002 ○2 European Standard EN12469:2000 ○3 Chinese Standard YY0569-2005
Front window is sealed, and with pairs of gloves connecting to the operation area, product is transferred by the delivery window. And there is no out-connected valve
○2 100% exhaust
100% air exhaust, no air recirculation, and air is exhausted by three ULPA filters and to the room directly. If the air needs to be exhausted to outdoors, another out connected duct need to be ordered, and extra duct and motor are required.
○3 Complete negative pressure
The two motors design makes interior of cabinet is complete negative pressure, and can reach -274pa, triple layers filter film, ensures operation’s security, neither substance nor polluted air will leak out.
