Description
Polycarbonate membrane filters with a pore size of 0,22 µm and a diameter of 47 mm are white laboratory membrane discs for defined filtration and separation applications. The 0,22 µm pores enable retention of fine particulates during sample clarification, analytical preparation and related steps linked to water purification and dialysis support. A 47 mm diameter ensures compatibility with common filter holders and funnels used in vacuum and pressure filtration assemblies. Packs of 100 pc(s) provide a practical working quantity for repeated use in research, quality-control and routine laboratory workflows. The white polycarbonate surface supports straightforward visual inspection of retained material after filtration. These membranes are offered by manufacturer MERCK MILLIPORE within the standard labware range for filtration media. Pack weight is 1,160 kg according to the listed specification. The discs are intended for single-pass membrane filtration protocols that specify polycarbonate at 0,22 µm pore size and 47 mm diameter, integrating readily into conventional laboratory separation setups.
This article is part of Membrane filters, in Filtration.

Questions about Polycarbonate-Membrane filters, white Ø 47 mm, pore size 0.22 µm, 100 unit(s)
What is this article?
Polycarbonate-Membrane filters, white Ø 47 mm, pore size 0.22 µm, 100 unit(s) is the article on this page. Luminix Health distributes MERCK MILLIPORE 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.
