Description
PORAFIL CA membrane filter is a white cellulose acetate (CA) disc filter with a defined pore size of 0,20 µm and a diameter of 25 mm. Designed as a laboratory membrane filter, it provides a consistent filtration surface for aqueous and compatible sample handling where fine particulate retention is required. The cellulose acetate membrane material combines mechanical handling strength with a uniform pore structure suited to routine analytical and process filtration workflows. Each unit is supplied non-sterile and is intended for use according to standard laboratory filtration practice. Packs contain 100 pieces, supporting repeated daily use in research, quality-control, and industrial laboratory settings. These PORAFIL CA filters from manufacturer Macherey-Nagel are specified with a 25 mm diameter that fits common small-scale filter holders and syringe-filter assemblies of matching size. Clear marking of pore width and diameter helps operators select the correct membrane for the intended separation step without ambiguity. The compact disc format simplifies storage and dispensing at the bench while maintaining dimensional consistency across the pack.
This article is part of Membrane filters, in Filtration.

Questions about PORA CA, white, PW:0,20 µm, d: 25 mm
What is this article?
PORA CA, white, PW:0,20 µm, d: 25 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.
