Understanding the Biological Safety Cabinet

The AutoLabGard ES (Energy Saver) NU-125 Mini-Room is designed after a Class II, Type A2 Biological Safety Cabinet on a larger scale to provide Class II protection for personnel, product, and the environment. The mini-room can be used for applications involving high-throughput robotic systems, large high-speed cell sorters, ultra-centrifuges, and laboratory equipment requiring Class II protection from potentially harmful aerosols and airborne particles. The NU-125 AutoLabGard ES is constructed with an interior stainless steel floor and wall panels that are gasketed and bolted together. Painted exterior Cold Rolled Steel (CRS) cover panels are gasketed and bolted to the stainless wall panels that make up the negative pressure plenum. Painted CRS blower modules are mounted on top of the wall panels and contain both the supply and exhaust HEPA filters along with the ultra-high efficiency DC ECM motors. Stainless steel doors complete the cabinet enclosure with a hinged window assembly mounted on each door providing an 8 inch (203mm) access opening. If additional access is needed to the interior for user or system interfaces (i.e. power/computer cables, process tubing, etc.), negative pressure pass through ports may be added to the sides or rear of the enclosure that maintain enclosure containment. The airflow pattern of the NU-125 AutoLabGard ES is identical to any class II, type A2 biosafety cabinet. Room air is pulled into the cabinet through the work access opening at an average velocity of 105 fpm (.53 m/s) to provide an air barrier. Engineered with an ultra-high efficiency motor the AutoLabGard lowers operating costs by using less electricity and increasing filter life with less heat output. Each NU-125 is tested and comes with a certified copy to tests consistent with standard NSF/ANSI 49. Contact NuAire today to start your high-throughput robotic system enclosure consultation.

LabGard® Air NU-543 Class II, Type A2 Biological Safety Cabinet offers the very best in personnel, product, and environmental protection by monitoring and controlling real-time airflow through the use of an airflow sensor, and displays airflow speeds on the OLED interface. The ability to choose up to three (3) different access opening heights allows our customers the option to select a larger access opening to improve technician movement and reach; select a smaller access opening to lower your total cost of ownership; or select somewhere in-between to get the best of both heights.

The LabGard NU-813 provides personnel protection for handling aerosols and particulate matter of low risk assessment though a 99.99% efficient HEPA filter. The Class I Safety cabinet allows room air to enter the hood, flowing past the operator into the work access opening. This provides an air barrier which minimizes contaminants generated within the hood work zone from migrating into the room.
