<P> 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 . </P>
