NuAire Class II, Type B2 Biological Safety Cabinets feature downflow air drawn from within the laboratory or outside air. No downflow air is drawn from the cabinet exhaust air. All downflow and inflow air is exhausted through a HEPA filter without recirculation within the cabinet. All contaminated ducts and plenums are maintained at negative pressure. The Type B2 Biological Safety Cabinet may be used for work with volatile toxic chemicals and radionuclides as required as adjuncts to microbiological studies.
The LabGard® ES (Energy Saver) NU-430 Total Exhaust Biological Safety Cabinet (BSC) may be used for work with non-flammable, non-explosive volatile chemicals and radionuclides by providing personnel, product, and environmental protection by exhausting 100% of contaminated air.
The LabGard ES 435 Biological Safety Fume Hood is designed to standard NFPA-45 and UL 1805. Exterior outlets, valves, and fire rated HEPA filters ensure a proper environment for use of flammable liquids, chemicals, isotopes, and radionuclides.
