Description
qpore® membrane filters in pure cellulose acetate (CA) are hydrophilic, non-sterile discs for laboratory filtration where low binding is essential. With a 0,45 µm pore size and 47 mm diameter, these CA membranes rank among filter types that show very low binding properties, helping preserve native protein composition and concentration. High filtration throughput reduces the frequency of filter changes during larger sample series. They are well suited to filtration of proteins and enzymes, sterile filtration of cell-culture media and related applications in which recovery of the original biomolecule profile is critical. The hydrophilic cellulose acetate surface supports aqueous workflows typical of life-science and analytical laboratories. Packs of 200 pieces from manufacturer neolab - Labor provide a convenient stock format for routine membrane filtration. These qpore® CA membranes offer a practical choice whenever gentle handling of sensitive proteinaceous samples and efficient volume processing are required side by side on the bench.
This article is part of Membrane filters, in Filtration.

Questions about qpore® membrane filters, CA, non-sterile, 0.45 µm, Ø 47 mm
What is this article?
qpore® membrane filters, CA, non-sterile, 0.45 µm, Ø 47 mm is the article on this page. Luminix Health distributes neolab 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.
