Description
PORA CA membrane filter, white, pore size 0,20 µm, diameter 13 mm is a cellulose acetate (CA) disc from the PORAFIL range for laboratory filtration. Cellulose acetate membranes are commonly chosen for aqueous sample clarification and fine particle retention where good wettability supports smooth flow. The defined pore size of 0,20 µm enables fine filtration steps, while the 13 mm diameter matches correspondingly small filter holders and compatible housings. White membrane appearance aids visual inspection of retained material during and after filtration. Each pack contains 100 pieces from manufacturer Macherey-Nagel, supporting high-throughput sample preparation in research, quality control and routine analytical workflows. These non-sterile filters are intended for general laboratory use; operators should select holders designed for 13 mm membranes and verify chemical compatibility of cellulose acetate with the intended solvent system. Compact pack format and consistent geometry help standardise filtration protocols across multiple workstations handling small sample volumes.
This article is part of Membrane filters, in Filtration.

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