Description
PORAFIL CM membrane filter, white, is a laboratory membrane filter disc with a pore size of 0,45 µm and a diameter of 50 mm. These white CM membranes support microfiltration tasks that need a defined pore width for particle retention and sample clarification in analytical laboratories. They are supplied in packs of 100 pieces, offering convenient replenishment for everyday filtration with matching 50 mm holders. The PORAFIL CM series from manufacturer Macherey-Nagel emphasises consistent disc geometry and easy handling at the bench. Non-sterile construction makes the filters appropriate for general laboratory use rather than sterile or aseptic applications. The 0,45 µm pore size is widely applied where fine particulate control is needed without moving into ultrafiltration. Uniform white membranes simplify inspection during setup and after use. Choose this 50 mm diameter when your filtration hardware is built around that format and you require dependable 0,45 µm performance in a multi-piece laboratory pack.
This article is part of Membrane filters, in Filtration.

Questions about PORA CM, white, PW:0,45 µm, d: 50 mm
What is this article?
PORA CM, white, PW:0,45 µm, d: 50 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.
