Labculture® Class II Type A2 Biological Safety Cabinet (Low Noise)
Esco Labculture® Class II Type A2 Biological Safety Cabinet (Low Noise) combines a multitude of design, construction, and proprietary technological considerations to provide optimum operator, product, and environmental protection. Utilizing 2 minipleat ULPA (Ultra Low Penetration Air) filters which operate at a typical efficiency of 99.999%, these filters surpass the conventional HEPA (High Efficiency Particulate Air) filters in contamination protection. Esco Labculture® features a 10-degree sloped front for maximum operator comfort. A single-piece stainless steel work zone and the absence of screws or connectors in the work zone facilitates ease-of-cleaning after experiments.

Key Features:
The Class II Type A biological safety cabinet is the most common Class II cabinet
It is also the
most common safety cabinet of all the different types available
The Class II Type A biological safety cabinet is the most common Class II cabinet
It is also the most common safety cabinet of all the different types available
It has a common plenum from which 30% of air is exhausted, and 70% re-circulated to the work area as the downflow
If trace amount of toxic chemicals is employed as an adjunct to microbiological processes, type A cabinets should be exhaust ducted
Exhaust HEPA filtration only removes airborne aerosols including biohazards, and not chemical fumes
It has a common plenum from which 30% of air is exhausted, and 70% re-circulated to the work area as the downflow
If larger amount of vaporizing toxic chemicals is used, type B cabinets should be used instead of type A
Stated from NSF/ANSI 49:2010, both the Class II Type A1 and Type A2 must have the positively-pressurized contaminated plenum to be surrounded by negative pressure
In case there is a leakage on the positive plenum, the leaking aerosol will be pulled by the negative pressure back to the positive plenum, and it will not leak out
In the A2 cabinet, about 70% of air from the positive plenum is recirculated as downflow, and the remaining 30% is discharged to the lab through the exhaust filter
