GVS Filter Technology products

GVS Life Sciences Cellulose Acetate (CA) Filtration Membrane is a supported, hydrophilic membrane that exhibits naturally low protein binding. Composed of cellulose acetate internally supported by an inert polyester web, the resulting membrane has dimensional stability. This provides higher throughputs than competitor offerings and reduces the amount of filter changes needed during filtration of proteinaceous solutions. It is ideal for use in filtration applications where maximal recovery of protein is critical. GVS Life Sciences CA Membrane is available in roll widths from 25 mm (1 in) to 30 cm (12 in), as well as in sheets and disks that can be customized to meet your application and size requirements. 

GVS Life Sciences Polyethersulfone (PES) Filtration Membrane is naturally hydrophilic, has low extractables and is cast from pure polyethersulfone polymer. This strong, microporous membrane is constructed from a high-temperature polyethersulfone polymer that is acid and base resistant. Its strength and durability are advantageous during usage that involves aggressive handling or automated equipment. It is designed to remove particulates during general filtration, and its low protein and drug binding characteristics make it ideally suited for use in life sciences applications. GVS Life Sciences PES Filtration Membrane is available in roll widths from 1.27 cm (0.5 in) to 79 cm (31 in), as well as in cut sheets and disks that can be customized to meet your application and size requirements.

GVS PCTE Membrane is made from a thin, microporous polycarbonate film material. It is ideally suited for use in blood assays and high-purity and general filtration. Though polycarbonate is hydrophobic, the membrane is treated with a wetting agent to make it hydrophilic.
