PES (Polyethersulfone) Membrane Filter, Hydrophilic, White, Non-sterile, Plain Discs, 0,45 μm, 25 mm, 100 pcs/pack
Article no.: PES04525BL
Our hydrophilic PES membranes have a particularly high density of pores. As a result, they achieve an outstanding flow rate of aqueous solutions. In addition, their polymeric fiber material allows a high mechanical strength in end devices. With their asymmetric membrane structure, i.e. larger pore openings at the inlet surface and a narrowing of the pore diameter towards the bottom of the membrane, they have a clear advantage over the usual symmetric pore structure.
Their low non-specific protein binding makes them suitable for filtering biological and pharmaceutical solutions without any effects on the ingredients, due to adsorption or decomposition.
Their low level of extractables prevents contamination of culture media, preparations of drugs, pharmaceuticals or infusion solutions. In addition, they pass the strict test for biocompatibility and cytotoxicity according to USP Standards.
Depending on your application and need, a pes membrane filter from our selection will provide the quality and results you need.
Standard Features
Made entirely from pure hydrophilic Polyethersulfone
Recommended for aqueous samples, biological applications and protein filtration
Particularly high flow rate, even with viscous liquids, due to their high porosity
