Description
Polycarbonate membrane filters with a pore size of 0,4 µm and a diameter of 90 mm are white disc membranes designed for laboratory filtration and separation. These larger polycarbonate filters support particle retention, sample clarification and membrane filtration steps where a 90 mm format is required in research, analytical or quality-control environments. The 0,4 µm pore size delivers a defined retention profile across the broad disc surface, suitable for higher-volume or larger-area filtration setups. Packs contain 30 pc(s) of white polycarbonate discs, matching typical consumption for this diameter. Pack weight is 0,050 kg. Supplied by manufacturer MERCK MILLIPORE, the membranes fit standard labware workflows covering filtration, separation and related sample-preparation tasks. The white 90 mm geometry facilitates handling and installation in compatible large-diameter holders. Laboratories that specify polycarbonate membrane media at 0,4 µm and 90 mm can use these filters directly in established protocols for routine separation and filtration work.
This article is part of Membrane filters, in Filtration.

Questions about Polycarbonate-Membrane filters, white Ø 90 mm, pore size 0.4 µm, 30 unit(s)
What is this article?
Polycarbonate-Membrane filters, white Ø 90 mm, pore size 0.4 µm, 30 unit(s) is the article on this page. Luminix Health distributes MERCK MILLIPORE 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.
