Description
PTFE membrane filters without support with a pore size of 5,0 µm and a diameter of 90 mm are laboratory membrane discs for filtration and separation work. Each piece is an unsupported PTFE membrane structure offered as a plain 90 mm disc at the stated 5,0 µm pore rating, intended for use in compatible filter holders and membrane filtration assemblies. The pack size is 25 pc(s) with a pack weight of 0,125 kg, suited to routine bench filtration and method set-up. These membrane filters from manufacturer MERCK MILLIPORE address filtration and separation needs in analytical, research, and quality-control laboratories that specify PTFE media without support backing. The unsupported construction provides a PTFE filtration layer alone, without an added support structure, when a pure membrane format is required. With a clearly defined 5,0 µm pore size and standard 90 mm diameter, the discs fit established membrane-filter workflows for sample preparation and particulate handling. Laboratories working under labware filtration categories—including membrane filtration and related separation steps—can select this format whenever a 5,0 µm PTFE membrane without support at Ø 90 mm is specified for the method.
This article is part of Membrane filters, in Filtration.

Questions about PTFE-membrane filters without support, structure, Ø 90 mm, pore size 5.0 µm
What is this article?
PTFE-membrane filters without support, structure, Ø 90 mm, pore size 5.0 µm 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.
