Description
PORA CA membrane filters are white cellulose acetate (CA) discs with a pore size of 0,80 µm and a diameter of 47 mm. These PORAFIL CA membranes are designed for laboratory filtration that needs a defined pore structure in a hydrophilic cellulose acetate matrix. Delivered in packs of 100 pieces, they support sample clarification, particle retention and general aqueous filtration in analytical and research environments. The 47 mm diameter matches widely used filter holders for larger sample volumes, offering greater filtration area while retaining the 0,80 µm pore specification. The white membrane surface helps operators observe retained material during use. Cellulose acetate is a standard choice for many aqueous buffers and process streams when CA performance is required. These membrane filters from manufacturer Macherey-Nagel belong to the PORAFIL CA series and are supplied non-sterile for routine laboratory applications. Teams can incorporate the 0,80 µm, 47 mm discs into established workflows for particulate control, prefiltration and sample preparation prior to further analysis, relying on the stated pore width and diameter for reproducible handling throughout the hundred-piece pack.
This article is part of Membrane filters, in Filtration.

Questions about PORA CA, white, PW:0,80 µm, d: 47 mm
What is this article?
PORA CA, white, PW:0,80 µm, d: 47 mm is the article on this page. Luminix Health distributes Macherey-Nagel 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.
