Polyester Track Etched (PETE), Diameter 142 mm, Pore Size 5.0 μm, Plain, GVS Group (CAT#: STEM-FC-1158-LC)

GVS PETE Membrane manufactured by GVS Group is made from a thin, translucent polyester film with a smooth, flat surface containing pores of controlled diameter and number. The membrane has better solvent resistance than polycarbonate, making it ideal for use in blood assays or general filtration where chemically aggressive solvents may be used. The membrane can capture all particles larger than the precisely controlled pore size on its surface. The membrane is produced through a two-step proprietary manufacturing process to obtain increased control over pore size and density to ensure the physical properties of each membrane precisely fit your specifications.
