Description
Hydrophobic PTFE membrane filters with a pore size of 0,45 µm and a diameter of 47 mm are laboratory disc membranes intended for filtration work that benefits from strong chemical resistance and reliable particle retention. These white, unsterile PTFE membranes present a hydrophobic surface suited to organic solvents, gases and other non-aqueous media commonly handled in analytical and preparative workflows. Packaged as 100 pc(s), the discs fit standard 47 mm filter holders and vacuum filtration assemblies used across research and quality-control laboratories. The 0,45 µm pore rating supports clarification and fine particulate retention while remaining practical for routine solvent handling. Manufactured by filtraTECH, the membranes offer the broad chemical compatibility and thermal stability associated with polytetrafluoroethylene, extending their use beyond the limits of many conventional polymer filters. They serve as a straightforward consumable for sample preparation, solvent filtration and related laboratory applications where a consistent hydrophobic PTFE medium in a convenient multi-piece pack is required.
This article is part of Membrane filters, in Filtration.

Questions about Hydrophobic PTFE membrane filter 0,45µm, 47 mm
What is this article?
Hydrophobic PTFE membrane filter 0,45µm, 47 mm is the article on this page. Luminix Health distributes filtraTECH 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.
