when should a laminar flow cabinet be used
Laminar flow cabinet A laminar flow cabinet or laminar flow closet or tissue culture hood is a carefully enclosed bench designed to prevent contamination of semiconductor wafers, biological samples, or any particle sensitive materials. Air is drawn through a HEPA filter and blown in a very smooth, laminar flow towards the user. Due to the direction of air flow, the sample is protected from the user but the user is not protected from the sample. The cabinet is usually made of stainless steel with no gaps or joints where spores might collect.[1]
Cupboard An airing cupboard is a storage space, sometimes of walk-in dimensions, containing a water heater; either an immersion heater for hot running water or a boiler for central heating water. Shelves, usually slatted to allow for circulation of heat, are positioned above or around the heater to provide storage for clothing, typically linen and towelling. The purpose is to allow air to circulate around the stored fabrics to prevent damp forming. A shelf can also be used to fully remove traces of damp from dried clothing before it is put away in drawers and wardrobes. Other names include "boiler cupboard", or (in Ireland) "hot press". Airing cupboards are mostly built-in (see below). A drying cabinet is an electrical version.
