Description
PORA NC membrane filters are white nitrocellulose membrane discs with a pore size of 0,45 µm and a diameter of 47 mm for laboratory membrane filtration. The material is cellulose nitrate and cellulose mixed ester (CN, MCE), delivering a defined porous matrix for clarification and particle retention in analytical and preparative workflows. Each package holds 50 pieces, ensuring a ready supply for repeated filtration steps in research and quality-control environments. The white surface facilitates visual checking of retained material once filtration is complete. These PORAFIL NC membranes from manufacturer Macherey-Nagel are supplied non-sterile for general laboratory use with compatible aqueous and organic solvents. The 47 mm diameter suits standard filter holders and larger-volume filtration setups commonly found in the laboratory. Consistent 0,45 µm porosity supports standardised particulate removal across batches. At a net weight of 0,03 kg per pack, the discs remain easy to store and handle. This PORA NC variant offers mixed-ester membrane performance in a practical 50-piece pack for routine filtration tasks.

Questions about PORA NC, white, PW:0,45 µm, d: 47 mm
What is this article?
PORA NC, white, PW:0,45 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.
