Biological safety cabinets (biosafety cabinets) come in several classes (I, II, and III) that offer varying levels of protection from hazardous or contagious materials. For all classes of biological safety cabinet, the air is HEPA (high efficiency particulate air)-filtered before being released as exhaust. A Class I biosafety cabinet is designed to protect the user and the environment, not the sample as negative pressure is used to pull outside air in across the workspace.
Class II biological safety cabinets are divided into four subtypes (A1, A2, B1, and B2) and have the additional feature of protecting the sample as the air supply is HEPA-filtered before passing over the workspace. The Class II subtypes differ in the amount of recirculated air within the cabinet.
Class III biosafety cabinets (also known as gloveboxes) provide maximum protection for work in biosafety level 4 containment labs. A class III biosafety cabinet is a hermetically-sealed glovebox with access through a dunk tank or double-door box that allows for decontamination.

| Description | The LabGard Containment Cabinet NU-813 is offered as a Class I Containment Cabinet equipped with a HEPA filter. In the Class I configuration, the NU-813 provides personnel protection for handling low risk aerosols and particulate matter. Room air enters the Cabinet, flowing past the operator into The LabGard Containment Cabinet NU-813 is offered as a Class I Containment Cabinet equipped with a HEPA filter. In the Class I configuration, the NU-813 provides personnel protection for handling low risk aerosols and particulate matter. Room air enters the Cabinet, flowing past the operator into the work access opening providing an air barrier which minimizes contaminants generated within the cabinet work zone from migrating into the room. The air flows through the cabinet carrying contaminants with it, exiting through a HEPA filter as a Class I Cabinet....

Read More | The LabGard ES (Energy Saving) NU-427 Class II, Type B1 Laminar Flow Biological Safety Cabinet (BSC) is a bench/table top model, utilizing an Energy Saver DC ECM motor optimally determined forward curved fan for each model size/width to maximize both energy efficiency and filter loading capacity. The LabGard ES (Energy Saving) NU-427 Class II, Type B1 Laminar Flow Biological Safety Cabinet (BSC) is a bench/table top model, utilizing an Energy Saver DC ECM motor optimally determined forward curved fan for each model size/width to maximize both energy efficiency and filter loading capacity. The Energy Saver ECM motor is controlled via a solid-state DC motor controller that provides automatic compensation (constant volume control) for both filter loading and line voltage variances. The NU-427 BSC is a product resulting from the development of the "laminar flow" principle and the application of environmental controls as required in the field of biological research or chemical containment. The NU-427 BSC when used with proper technique, is an effective laboratory aid in obtaining the optimum control over product quality while reducing the potential for exposure of both product and personnel to airborne biological or particulate chemical agents in low to moderate risk-hazard research and use of the BSC to work with chemicals and trace amounts of radio nuclides required as an adjunct to microbiological studies, as prescribed by the Center for Disease Control (CDC) Atlanta, Georgia....
