Description
Hydrophobic PTFE membrane filter 0,45 µm, 90 mm is a white, unsterile laboratory membrane disc built around a hydrophobic polytetrafluoroethylene film. Its 0,45 µm pore size and 90 mm diameter provide a defined filtration area for holders and funnels that take this standard disc size. Hydrophobic PTFE is selected when the application benefits from a non-wetting fluoropolymer surface and the chemical robustness associated with PTFE membranes. The membrane is supplied white and unsterile, so any sterilisation, pre-wetting with suitable solvents, or aseptic technique remains under laboratory control. Packaged as 100 pc(s), the product supports series filtration, method work, and routine replenishment without frequent reordering of small packs. These membrane filters from manufacturer filtraTECH sit within ordinary lab material ranges used for clarification and particulate control where a 0,45 µm hydrophobic PTFE grade is specified. Matching the 90 mm format across instruments simplifies consumable standardisation, while the explicit pore-size marking reduces confusion with finer or hydrophilic alternatives kept in the same store. The combination of material, micron rating, and diameter makes the designation easy to place in existing SOPs and ordering lists.
This article is part of Membrane filters, in Filtration.

Questions about Hydrophobic PTFE membrane filter 0,45µm, 90 mm
What is this article?
Hydrophobic PTFE membrane filter 0,45µm, 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.
