Description
PORA NC membrane filter is a white nitrocellulose membrane disc with a pore size of 0,20 µm and a diameter of 13 mm, intended for laboratory filtration and particle retention applications. Manufactured from cellulose nitrate / mixed cellulose ester (CN, MCE), these PORAFIL NC membranes provide a uniform porous structure suited to clarification, microbiological sample preparation and general analytical filtration workflows. Each pack contains 50 pieces and is supplied non-sterile. The compact 13 mm format fits standard small-diameter filter holders used in research and quality-control laboratories. Available from manufacturer Macherey-Nagel, the filters are not classified as dangerous goods under the cited transport provisions (ADR SV286 / IATA A122), simplifying logistics for routine stock. They support everyday membrane filtration tasks where a defined 0,20 µm pore rating and nitrocellulose chemistry are specified, offering a practical consumable for aqueous and compatible solvent systems in life-science and analytical environments.
This article is part of Membrane filters, in Filtration.

Questions about PORA NC, white, PW:0,20 µm, d: 13 mm
What is this article?
PORA NC, white, PW:0,20 µm, d: 13 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.
