Biosafety Cabinets

These units are used for biological applications to remove potentially infectious agents such as microbes and spores. The air is passed through a HEPA filter and back into the room. The filter removes small particles but not vapors and gases, so BSCs should not be used with chemicals.

Non-Hood units, Laminar Flow – These units are not safety devices. They protect the work (such as RNA), not the user. The air flows back at the user away from the work through many tiny holes in a laminar pattern.
