Description
PVDF membrane filters, hydrophobic, with a pore size of 0,22 µm and a diameter of Ø 90 mm, are large-format laboratory discs for filtration and separation applications. Made from polyvinylidene fluoride in a hydrophobic configuration, they suit solvent-based and non-aqueous media where water wettability is not required. The 0,22 µm pore size supports fine particulate control and clarifying operations in research, analytical, and industrial laboratory environments. Each pack provides 50 pc(s) of 90 mm membranes, giving a generous filtration area for higher-volume or larger-holder setups while remaining manageable on the bench. Pack weight is 0,125 kg. These membranes come from manufacturer MERCK MILLIPORE and fit established membrane-filtration practice within labware categories covering filtration, water purification, dialysis, and separation. Specify this 90 mm hydrophobic PVDF disc with 0,22 µm pores when methods call for a broad active surface, consistent pore geometry, and solvent-compatible membrane chemistry for routine or developmental sample processing.
This article is part of Membrane filters, in Filtration.

Questions about PVDF-Membrane filters, hydrophobic, Ø 90 mm, pore size 0.22 µm, 50 unit(s)
What is this article?
PVDF-Membrane filters, hydrophobic, Ø 90 mm, pore size 0.22 µm, 50 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.
