Precise HEPA-Filtered Glove Boxes have inlet and outlet HEPA filters and provide a leak-tight physical barrier to protect the operator from hazardous airborne particulates and powders. These boxes have uses in pharmaceutical research, nanotechnology and biochemistry. Microorganisms, low-level radiochemicals, chemical carcinogens and asbestos may also be used in these boxes. These boxes may be used for cleanroom applications requiring ISO Class 3 (ISO 14644-1) conditions. Labconco HEPA Filtered Glove Boxes may be appropriate for use as containment isolators for applications involving compounds assigned ISO 4 and ISO 5 Banding Levels.
