Membrane Filters The membrane filter is the most common type of filtration system used in modern microbiology laboratories. Membrane filters, in the form of discs, can be assembled into pressure-operated filter holders for syringe mounting and in-line use or vacuum filtration tower devices for filtration of liquid. Filtration technology has progressed from early attempts using sand, gravel and cinders to today's membrane filters which are capable of removing microorganisms and sterilizing pharmaceutical products. Typically, the membranes used for filter sterilisation of liquids are made of cellulose esters or other polymers and have pore diameters between 0.2 and 0.45 μ m. As medium passes through the filter, bacteria and other particles with dimensions greater than the pore size are screened out and collect on the surface of the membrane. Filter membrane thickness—Filter . We provide effective filtration sterilization and clarification solutions for global laboratory industries. Membrane processes are increasingly used for removal of bacteria, microorganisms, particulates, and natural organic material, which can impart color, 3. These protect the contents of the tanks or other containers against contamination by the air that enters or leaves them as occasioned by the addition or withdrawal of their stored liquids.
