Description
PES membrane filters with a pore size of 0,45 µm and a diameter of 47 mm are hydrophilic polyethersulfone discs packed as 200 pieces for laboratory liquid filtration. The membrane is especially suitable for work with cell-culture media, where clarifying aqueous formulations before use or sterile handling steps is routine. Hydrophilic PES offers a high filtration speed together with strong mechanical robustness and broad resistance to many aqueous solvents, supporting reliable throughput on the bench. Low protein adsorption helps limit unwanted binding when protein-containing media or buffers are filtered, which is valuable in cell-culture and related life-science workflows. The 47 mm diameter matches common filter holders, while the 0,45 µm pore size addresses fine particulate removal in everyday protocols. These membranes from manufacturer Labbox (BRANCHIA line) give laboratories a practical consumable for media preparation and general aqueous filtration. Select solvent compatibility and operating pressure according to your method so each disc performs consistently across repeated culture and analytical tasks.

Questions about PES Membrane Filters, Pore: 0,45 µm, Ø47mm, 200 pcs
What is this article?
PES Membrane Filters, Pore: 0,45 µm, Ø47mm, 200 pcs is the article on this page. Luminix Health distributes Labbox 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.
