Description
PES membrane filter, 293 mm diameter with 0,8 µm pore size, is a hydrophilic polyethersulfone disc engineered for laboratory filtration of aqueous solutions. The membrane combines high flow rates with low non-specific protein adsorption, helping preserve sample integrity during clarification, sterilising filtration and buffer preparation. Chemical resistance across the pH range 1–14 allows use with acidic and alkaline media commonly encountered in life-science and analytical workflows. Supplied by manufacturer Sartorius as a single piece, the large 293 mm format suits high-volume or process-scale filtration setups. Polyethersulfone construction provides mechanical robustness while remaining compatible with a broad spectrum of aqueous laboratory reagents. Typical applications include media filtration, protein solution clarification, buffer filtration and general particle removal where low protein binding and rapid throughput are advantageous. The hydrophilic character supports easy wetting without pre-treatment, simplifying handling in routine laboratory practice. Consistent pore-size control ensures reproducible retention performance for demanding filtration tasks in research and quality-control environments.

Questions about PES Membrane , 293 mm, 0.8 m
What is this article?
PES Membrane , 293 mm, 0.8 m is the article on this page. Luminix Health distributes Sartorius for laboratory use. It sits in Membrane filters, inside Filtration, in Consommables.
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.
