Description
PORAFIL CA membrane filter is a white cellulose acetate (CA) membrane filter with a pore size of 0,80 µm and a diameter of 220 mm. It serves laboratory membrane filtration tasks that need a defined pore width in an extra-large disc format. Cellulose acetate forms the filter medium, presented in white for straightforward visual assessment of the membrane during handling. Packs contain 25 pieces, a practical unit quantity for repeated filtration steps and stock use in research and quality-control laboratories. Available from manufacturer Macherey-Nagel, these PORAFIL filters are supplied non-sterile within the membrane filter product group. The 220 mm diameter suits procedures and equipment configured for this large disc size, while the 0,80 µm pore size sets the retention characteristic of the medium. Consistent specification of material, pore size and diameter across the pack supports uniform preparation when several samples are processed side by side. Net pack weight is 0,21 kg. Manufactured in Germany, this PORAFIL CA disc delivers the 0,80 µm cellulose acetate membrane format at 220 mm for laboratory filtration applications requiring a wide disc.
This article is part of Membrane filters, in Filtration.

Questions about PORA CA, white, PW:0,80 µm, d: 220 mm
What is this article?
PORA CA, white, PW:0,80 µm, d: 220 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.
