Description
Hydrophobic PTFE membrane filters with a pore size of 5,00 µm and a diameter of 90 mm are plain white, unsterile discs intended for laboratory filtration work where chemical resistance and a defined pore structure matter. Manufactured from polytetrafluoroethylene, the membrane supports sample preparation, particle retention and solvent-compatible filtration steps across analytical and process laboratories. The 5,00 µm rating suits coarser clarification and pre-filtration duties, while the 90 mm format fits standard filter holders used in routine workflows. Each unit is supplied unsterile and white, so users can apply their own sterilisation or handling protocol as required by the method. Pack size is 100 pc(s), giving a practical stock quantity for high-throughput benches. These hydrophobic PTFE membrane filters from manufacturer filtraTECH combine a clear pore specification with a widely used diameter, making them straightforward to specify for organic solvents, aggressive media and general laboratory filtration where PTFE chemistry is preferred.
This article is part of Membrane filters, in Filtration.

Questions about Hydrophobic PTFE membrane filter 5,00µm, 90 mm
What is this article?
Hydrophobic PTFE membrane filter 5,00µm, 90 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.
