Window Type H = Hinged S = Sliding F = Fixed 
Bench Height NA = Not Applicable NP = Not Provided 
CBV = Concurrent Balance Value
Due to a change in nomenclature in NSF/ANSI 49  2002 “Class II (Laminar Flow) Biosafety Cabinetry,” Class II, Type A cabinets are now referred to as Class II, Type A1 and Class II, Types B3 and A/B3 cabinets as Class II, Type A2. Class II, Types B1 and B2 cabinets remain unchanged.
Biosafety cabinet models Listed under NSF/ANSI 49 are approved for use with a power supply of 115V/60Hz, unless otherwise noted. If biosafety cabinets have been approved for use with additional power supplies, the power supply will be indicated in the Official Listing.
