Profile: Advantec MFS, Inc. specializes in producing filtration media and related scientific products. Our filtration products include membrane filters, prefilters & depth media, filter holders, filtration accessories, cartridges and ultrafiltration. Membrane filters are polymer films with specific pore ratings. Membranes retain particles and microorganisms that exceed their pore ratings by acting as a physical barrier and capturing such particles on the surface of the membrane. Membranes are available in a variety of polymers, pore sizes, diameters, and surface types. Most membranes can be sterilized by autoclaving. Laboratory instruments include fraction collectors, magnetic stirrers, water baths, rocking incubators and electrophoresis units.
