Description
PORAFIL CA membrane filter is a white cellulose acetate (CA) membrane filter with a pore size of 0,80 µm and a diameter of 142 mm. It is intended for laboratory membrane filtration where a defined pore width and a large disc format are required. The filter medium is cellulose acetate, supplied in a plain white finish that supports clear visual handling of the membrane surface during preparation and use. Each pack contains 25 pieces, giving a practical quantity for routine filtration steps and multi-sample workflows in analytical and research laboratories. These PORAFIL discs from manufacturer Macherey-Nagel are supplied non-sterile and belong to the membrane filter category. The 142 mm diameter corresponds to holders and assemblies built for this disc size, while the 0,80 µm pore size defines the retention characteristic of the medium. Uniform material, pore size and diameter across the pack help keep parallel filtrations set up consistently. Net pack weight is 0,10 kg. Produced in Germany, this PORAFIL CA membrane provides the 0,80 µm cellulose acetate format at 142 mm for everyday laboratory filtration work.
This article is part of Membrane filters, in Filtration.

Questions about PORA CA, white, PW:0,80 µm, d: 142 mm
What is this article?
PORA CA, white, PW:0,80 µm, d: 142 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.
