Pall Gelman Versapor® Membranes
By Pall Life Sciences
Composed of an acrylic copolymer on a nylon substrate, resulting in a highly microporous hydrophilic membrane. Versapor® membranes are designed for applications that require a filter with excellent retention properties combined with tensile strengths in excess of 3,000 psi. Provided nonsterile in a variety of pore sizes and diameters. Sterilizable by UV or gamma radiation, 70% alcohol or EtO, if desired.
