Description
PTFE membrane filter discs, hydrophobic, 50 mm, 0,45 µm are plain laboratory membrane filters supplied without a support structure. These unsupported PTFE discs combine the inherent chemical inertness and hydrophobicity of polytetrafluoroethylene with a defined pore size of 0,45 µm, making them suitable for filtration of aggressive organic solvents, acids, bases, air and other gases. The 50 mm diameter matches standard laboratory filter holders and funnels used in analytical chemistry, sample preparation and quality-control workflows. Packaged in units of 100 pieces, the discs from manufacturer Berrytec provide a consistent, pure PTFE filtration surface free from backing-layer extractables. Hydrophobic character prevents spontaneous aqueous wetting, which is advantageous for venting applications and non-aqueous liquid clarification. The unsupported construction maximises chemical resistance and thermal stability while maintaining reliable particle retention. Each pack has a net weight of 0,1 kg and integrates directly into existing filtration setups for research and routine laboratory use.
This article is part of Sintered glass filter plates & discs, in Filtration.

Questions about PTFE hydrophobic membrane disc filter 50mm, 0,45µm
What is this article?
PTFE hydrophobic membrane disc filter 50mm, 0,45µm 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.
