LabGard® ES NU-427 Class II, Type B1 Biosafety Cabinet

Description

The LabGard ES NU-427 is a bench-top or table-top model biosafety cabinet with a Class II, Type B1 classification. This type is distinguished by a higher proportion of exhausted air compared to Type A2 cabinets, making it suitable for work involving low levels of volatile toxic chemicals or radionuclides as part of microbiological studies, per CDC guidelines. It incorporates an Energy Saver DC ECM motor paired with an optimized forward-curved fan, a configuration designed to maximize energy efficiency and filter loading capacity. A solid-state DC motor controller provides constant volume control, automatically adjusting for changes in filter resistance and line voltage to maintain a steady inflow velocity of 105 fpm (0.53 m/s). When used with correct technique, the cabinet serves as an effective containment device, helping to ensure product quality while minimizing potential exposure of personnel and samples to airborne biological or chemical particulates in moderate-risk research settings.
