Laminar flow cabinet
From Wikipedia, the free encyclopedia
Laminar flow cabinet or laminar flow closet is a carefully enclosed bench designed to prevent contamination of semiconductor wafers, biological samples, or any particle sensitive device. Air is drawn through a HEPA filter and blown in a very smooth, laminar flow towards the user. The cabinet is usually made of stainless steel with no gaps or joints where spores might collect.
Such hoods exist in both horizontal and vertical configurations.
Laminar flow cabinets may have a UV-C germicidal lamp to sterilize the shell and contents when not in use. (It is important to switch this light off as it will quickly give any exposed skin sunburn, and may cause cataracts)
Major manufacturers of laminar flow cabinets include Esco (http://www.escoglobal.com), Thermo-Electron Corporation (http://www.thermo.com), and NuAire, Inc. (http://www.nuaire.com).
