Description
PVDF membrane filters, hydrophilic, with a pore size of 0,45 µm and a diameter of Ø 25 mm are disc membranes for laboratory filtration and separation. The hydrophilic polyvinylidene fluoride construction is suited to aqueous media where controlled retention at the stated pore size is required in routine sample preparation. Pack size is 100 pc(s), giving a practical stock quantity for analytical, life-science and general chemistry workflows that use standard 25 mm holders. Geometry and pore rating are defined clearly so the discs can be matched to existing filter hardware without guesswork. Listed pack weight is 0,100 kg. These hydrophilic PVDF membrane filters from manufacturer MERCK MILLIPORE sit within the filtration and separation consumables range used for membrane filtration steps linked to water purification, dialysis-related handling and broader lab separation tasks. Choose this 0,45 µm, Ø 25 mm format when a hydrophilic PVDF disc in a multi-piece pack is needed for everyday filtration procedures that demand a defined pore size and diameter.
This article is part of Membrane filters, in Filtration.

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