PTFE membrane filter discs hydrophobic 25 mm, 0,45 µm provide unsupported PTFE filtration media for laboratory processes that require chemical resistance together with reliable particulate control. The hydrophobic discs feature a 25 mm diameter and a 0,45 µm nominal pore size, making them suitable for air and gas filtration as well as clarification of aggressive solvents. Because the membranes are supplied without a support structure, only pure PTFE contacts the process stream, reducing the risk of extractables and preserving sample integrity. Offered in packs of 100 pieces, the discs support high-throughput sample preparation, venting and general laboratory filtration duties. These filters from manufacturer Berrytec are valued in analytical and quality-control environments where consistent hydrophobic membrane behaviour is essential. With a net pack weight of 0,025 kg, the product is easy to store and handle alongside standard filtration hardware, helping laboratories maintain efficient workflows for both aqueous and organic matrices.
This article is part of Sintered glass filter plates & discs, in Filtration.

Questions about PTFE hydrophobic membrane disc filter 25mm, 0,45µm
What is this article?
PTFE hydrophobic membrane disc filter 25mm, 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 Verbruiksartikelen.
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.
