Gas pass through exhaust outlet filtering discharge.Two grades of Type B Biohazard Safety Equipments are the safety cabinet of connection gas extraction system.Connect safety cabinet
The blower fan connection emergency service power supply of exhaust manifolds, purpose can still keep safety cabinet negative pressure in the absence of power, in case hazardous gas is let out
Spill laboratory.Its front window air velocity minimum or measurement average value should be at least 0.5m/s (100fpm).The gas of B1 types 70%
Body is excluded by exhaust outlet high efficiency particle air filter, and 30% gas is recycled to work by air supply opening high efficiency particle air filter
Area.B2 types are 100% full row's type safety cabinet, and no inner loop air-flow can provide biological and chemically security control simultaneously,
The Experiment on Microbiology of additive can be used as using operating volatility chemicals and volatility core radiation.Three-grade biological safety cabinet be for
Biological safety protection grade is 4 grades of laboratories and designed that cabinet is completely airtight, and staff is by being connected to the gloves of cabinet
Operated, be commonly called as glove box, it is not contaminated to ensure that trial target passes in and out safety cabinet by two-door pass box, it is adaptable to Gao Feng
The biologic test of danger.
There is the problem of air filtration effect is poor in existing Biohazard Safety Equipment.
