Description
PES membrane 0,2 µm, 65 mm is a hydrophilic polyethersulfone filter disc engineered for high flow rates and minimal non-specific protein adsorption. The membrane withstands a wide pH range of 1 to 14, ensuring chemical stability in acidic to strongly alkaline media. Supplied in a pack of 50 pieces, these 65 mm diameter discs are intended for laboratory filtration of aqueous samples, protein solutions and buffers. Manufactured by Sartorius, the PES material wets spontaneously and delivers consistent throughput without additional pre-wetting steps. Low protein binding helps maximise recovery of valuable biomolecules during clarification or sterilising-grade filtration steps. The combination of defined 0,2 µm pore size and robust mechanical properties makes the membrane suitable for particle removal, sample preparation and microbiological workflows. Each disc maintains structural integrity under typical laboratory vacuum or pressure conditions. This format supports efficient multi-sample processing in research, quality-control and process-development laboratories requiring reliable hydrophilic membrane performance.
This article is part of Membrane filters, in Filtration.

Questions about PESMembran;0,2m;65mm;50pc
What is this article?
PESMembran;0,2m;65mm;50pc is the article on this page. Luminix Health distributes Sartorius for laboratory use. It sits in Membrane filters, inside Filtration, in Lab consumables.
A membrane filter is the disc itself, without a syringe housing. Pore size, polymer and diameter are the specification, and the disc has to sit in a holder. Gridded membranes are for counting colonies. A membrane and a filter paper of the same diameter are not interchangeable.
Filtration holds back what is larger than the pores and lets the rest through. Paper is the ordinary laboratory filter. A membrane has a stated pore size and a polymer that must survive the solvent. A syringe filter is that membrane in a housing on a syringe. Glass fibre takes a higher dirt load. Ultrafiltration holds back macromolecules and passes salts. The pore size, the chemical compatibility and the volume are the three choices. Laboratory apparatus around filtration is indexed under ISO laboratory apparatus.
