This strong, microporous film asymmetric 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. GVS PES Filtration Membrane is naturally hydrophilic without added wetting agents and has low extractables.

Hydrophilic: eliminates the need for wetting agents that can potentially interfere with analyses.

Low extractables: ensures test results will not be compromised by wetting agents or other extractables.

Low drug and protein binding: maximizes recovery of critical drugs or proteins.

Wide range of pore sizes: pore size range of 0.03 μm to 5.0 μm enables specific pore size selection for given applications.

Superior burst strength: protects the integrity of the membrane under high pressure.

Quality checks ensure lot-to-lot consistency, both down and across the polyester web, for dependable results every time.
