Description
PTFE membrane filters with laminated support structure provide a 0,22 µm pore size on a 90 mm diameter disc for laboratory membrane filtration. The PTFE membrane is laminated to a support structure that reinforces the filter during installation and use in larger-diameter holders. Unit quantity is 50 pc(s), with a pack weight of 0,125 kg, reflecting the larger disc format. These filters from manufacturer MERCK MILLIPORE are positioned in the membrane filter segment of laboratory filtration and separation supplies. The 90 mm diameter suits higher-volume or larger-area filtration setups, while the 0,22 µm rating keeps the pore specification consistent with related PTFE laminated discs. Laminated construction aids handling of the membrane and helps preserve disc flatness when loading into filtration hardware. The product supports standard laboratory workflows that call for PTFE membrane discs with defined pore size and laminated backing. Clear size and pore-size identification simplifies matching to holders and protocols used in research and analytical laboratories.
This article is part of Membrane filters, in Filtration.

Questions about PTFE-membrane filters with laminated, support struct.,Ø 90mm, pore size 0.22µm
What is this article?
PTFE-membrane filters with laminated, support struct.,Ø 90mm, pore size 0.22µm 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.
