Description
PTFE membrane filter discs hydrophobic 90 mm, 1,20 µm are specialised laboratory filtration media engineered for applications that require high chemical resistance and defined particle retention. Produced entirely from polytetrafluoroethylene without any supporting substrate, these hydrophobic discs remain unwetted by aqueous liquids while allowing free passage of organic solvents, acids, bases and gases. The 90 mm diameter suits standard filter holders, and the 1,20 µm pore size delivers consistent retention of particulates and aerosols in sample preparation, venting and clarification tasks. Their unsupported construction preserves the intrinsic purity, thermal stability and broad chemical compatibility of pure PTFE. Available in packs of 50 pieces from manufacturer Berrytec, the discs integrate readily into routine and specialised workflows. With a net pack weight of 0,1 kg they are convenient to store and handle. Laboratories rely on these membranes for reliable performance across demanding chemical environments in research, quality control, environmental analysis and pharmaceutical testing.
This article is part of Sintered glass filter plates & discs, in Filtration.

Questions about PTFE hydrophobic membrane disc filter 90mm, 1,20µm
What is this article?
PTFE hydrophobic membrane disc filter 90mm, 1,20µm 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.
