The gastight 30% exhaust / 70% recirculated air cabinet minimizes cross contamination of biologicals of low to moderate risk assessment in the absence of volatile toxic chemicals and protects the laboratory professional and environment from exposure to biologicals and/or chemical agents within the work zone.
The Labgard 437 Biological Safety Cabinet serves laboratory professionals better with significant improvements in increased personnel protection, product safety, simpler maintenance, lower life-cycle cost, and greater dependability.
This NuAire exclusive design results in a quiet, uniform down flow velocity over the sterile work zone. The HEPEXª Zero Leak Air Flow System prevents uneven particulate loading by eliminating direct blower blasts to the HEPA filter, spreading high static pressure over 100% of the filter surface.
The system surrounds all positive pressure Air Flow chambers and ducts with vacuum or negative air pressure relative to the laboratory. This eliminates the possibility of cabinet or gasket leaks and guards against HEPA filter failure. This system also allows for the change of the supply HEPA filter without having to expose the dirty, contaminated side of the HEPA filter to the laboratory or service technician.
The Labgard 437 is a 16 gauge pressure tight, all welded, 100% stainless steel shell. All welds are meticulously hand-finished and polished to be free of burrs. The shell is structurally reinforced to minimize vibration, noise levels and maintain a flat surface structure. The stainless steel is easily cleaned with all ducts, plenums, and penetrations for utilities sealed to prevent the escape of contaminates into the laboratory.
