Description
Polyethersulfone membrane filter Type 15407 is a hydrophilic laboratory membrane offering high flow rates together with low non-specific protein adsorption. The filter material provides broad chemical resistance across the full pH range from 1 to 14, making it suitable for demanding aqueous and buffer-based filtrations. This single-piece unit has a net weight of 0,139 kg and a gross weight of 0,150 kg. Produced by manufacturer Sartorius, the membrane supports efficient sample processing in analytical, preparative and quality-control workflows where protein recovery and consistent throughput are essential. Its inherently hydrophilic surface wets readily without pre-treatment, reducing handling steps and improving reproducibility. Typical uses include clarification of protein solutions, buffer filtration and general particle removal in life-science and pharmaceutical laboratories. The robust polyethersulfone matrix maintains integrity under varied chemical conditions while delivering reliable flow performance. Designed for routine laboratory filtration tasks, the Type 15407 membrane combines chemical durability with low binding characteristics to help preserve sample integrity throughout the filtration step.
This article is part of Membrane filters, in Filtration.

Questions about Polyethersulfone membrane 142 mm, 0,2m
What is this article?
Polyethersulfone membrane 142 mm, 0,2m 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.
