Description
PVDF membrane filters, hydrophobic, with a pore size of 0,45 µm and a diameter of Ø 25 mm are disc-type membrane filters for laboratory filtration and separation. The hydrophobic PVDF membrane is offered in a practical pack of 100 pc(s), giving laboratories a ready stock for repeated clarification and particulate-retention steps. At 25 mm diameter these filters fit common small-scale holders used in analytical and research workflows. The defined 0,45 µm pore rating supports consistent membrane filtration where a hydrophobic surface is preferred over water-wetting grades. Pack weight is 0,085 kg for the full unit quantity. These filters from manufacturer MERCK MILLIPORE belong to standard labware for filtration and separation and align with routine membrane-filter use in water-related, dialysis-adjacent and general sample-preparation settings. Hydrophobic PVDF construction guides solvent and sample compatibility choices during method setup, while the uniform disc geometry helps keep filtration conditions comparable across parallel runs. The combination of 0,45 µm pores and 25 mm format makes the product a straightforward option whenever hydrophobic membrane discs of this size are specified in laboratory protocols.
This article is part of Membrane filters, in Filtration.

Questions about PVDF-Membrane filters, hydrophobic, Ø 25 mm, pore size 0.45 µm, 100 unit(s)
What is this article?
PVDF-Membrane filters, hydrophobic, Ø 25 mm, pore size 0.45 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.
