A Laminar Air Flow Cabinet Manufacturer, also known as a tissue culture hood, is
an expertly constructed bench intended to keep semiconductor wafers, biological
samples, and other particle-sensitive materials free of contamination. A HEPA filter
is used to extract air, which is then blown in a very even, laminar flow in the
direction of the user. The sample is protected from the user due to the direction
of air movement, but the user is not protected from the sample. Typically composed of
stainless steel, the cabinet has no cracks or crevices where spores could grow.
