Description
Polycarbonate membrane filters with a pore size of 0,4 µm and a diameter of 47 mm are white disc membranes for laboratory filtration and separation applications. These polycarbonate filters are suited to particle retention, sample clarification and membrane-based separation steps commonly performed in research, analytical and quality-control laboratories. The widely used 47 mm diameter fits standard filter holders and funnels for larger sample volumes, while the 0,4 µm pore size provides a defined retention characteristic. Each pack supplies 100 pc(s) of white polycarbonate discs, supporting steady laboratory throughput. Pack weight is 0,120 kg. Offered by manufacturer MERCK MILLIPORE, the membranes align with established filtration and separation practices within the labware category. The white disc format enables straightforward mounting and handling in compatible apparatus. Facilities that already specify polycarbonate membrane media at 0,4 µm and 47 mm can incorporate these filters into routine sample-preparation and separation workflows without changing holder geometry or pore-size requirements.
This article is part of Membrane filters, in Filtration.

Questions about Polycarbonate-Membrane filters, white Ø 47 mm, pore size 0.4 µm, 100 unit(s)
What is this article?
Polycarbonate-Membrane filters, white Ø 47 mm, pore size 0.4 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.
