Description
PORA RC membrane filters are cellulose discs with a pore size of 0,45 µm and a diameter of 25 mm. Presented as PORAFIL RC membrane filters, they address laboratory filtration needs that call for a defined pore width in a widely used mid-size disc. Each pack holds 100 pieces, which is convenient for series work, method development and routine sample processing. The cellulose material forms a standard membrane matrix for aqueous media and common laboratory filtrations in analytical and preparative practice. These filters from manufacturer Macherey-Nagel align with holders and housings specified for 25 mm membranes and support clarification and particle-retention steps at the stated pore size. Discs are supplied non-sterile. Pack net weight is 0,02 kg. For buffer preparation, sample clean-up or general laboratory separation, this PORA RC format combines a 0,45 µm pore rating with a 25 mm diameter, giving a practical option for consistent day-to-day filtration on the laboratory bench.
This article is part of Membrane filters, in Filtration.

Questions about PORA RC, white, PW:0,45 µm, d: 25 mm
What is this article?
PORA RC, white, PW:0,45 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.
