Description
PTFE membrane filter discs hydrophobic 13 mm, 0,22 µm are specialised laboratory filtration media designed for demanding chemical environments and gas or solvent applications. These unsupported polytetrafluoroethylene discs combine a 0,22 µm pore size with a 13 mm diameter and inherently hydrophobic character, enabling effective retention of particles while resisting aggressive solvents and corrosive media. The absence of a support structure yields a pure PTFE membrane suitable for critical filtrations where minimal extractables are required. Supplied in packs of 100 pc(s) with a net weight of 0,025 kg, the discs are ready for use in syringe holders or compatible filtration devices. Produced by Berrytec, they deliver the thermal and chemical stability characteristic of PTFE together with precise dimensional consistency. Typical applications include solvent clarification, venting, and filtration of non-aqueous samples in analytical and research laboratories that require robust hydrophobic membrane performance.
This article is part of Sintered glass filter plates & discs, in Filtration.

Questions about PTFE hydrophobic membrane disc filter 13mm, 0,22µm
What is this article?
PTFE hydrophobic membrane disc filter 13mm, 0,22µm is the article on this page. Luminix Health distributes Berrytec for laboratory use. It sits in Sintered glass filter plates & discs, inside Filtration, in Lab consumables.
A sintered glass filter is a disc of fused glass particles with a porosity grade, often 0 to 5, from coarse to fine. It is cleaned and reused. The porosity number, not a micrometre guess, is the specification. Hydrofluoric acid and strong alkali attack the glass.
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.
