Description
PTFE membrane filters with laminated support structure are disc-type laboratory membrane filters offered with a pore size of 0,22 µm and a diameter of 25 mm. The PTFE membrane is combined with a laminated support structure that stabilises the filter during handling and mounting in standard holders. Pack size is 100 pc(s), with a pack weight of 0,085 kg, making the format practical for routine bench work and method development. These membrane filters from manufacturer MERCK MILLIPORE belong to the filtration and separation range used for laboratory membrane filtration tasks. The 0,22 µm pore rating and 25 mm diameter align with common disc-filter geometries employed in analytical sample preparation and related workflows. Laminated construction helps maintain membrane integrity while the PTFE filter media serves as the active separation layer. Suitable for integration into vacuum or pressure filtration setups that accept 25 mm discs, the product supports consistent use across research, quality-control and general laboratory filtration applications where a defined PTFE membrane with support structure is required.
This article is part of Membrane filters, in Filtration.

Questions about PTFE-membrane filters with laminated, support struct.,Ø 25mm, pore size 0.22µm
What is this article?
PTFE-membrane filters with laminated, support struct.,Ø 25mm, 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.
