PTFE membrane filter discs hydrophilic 25 mm, 3 µm are laboratory filtration media intended for aqueous and compatible solvent applications that require chemical resistance together with ready wettability. Each disc consists of a hydrophilic polytetrafluoroethylene membrane measuring 25 mm in diameter with a nominal pore size of 3 µm, enabling efficient particle retention and sample clarification in routine analytical workflows. The hydrophilic surface allows direct use with water-based solutions without the pre-wetting steps typically needed for untreated PTFE. Packaged as 100 pc(s) with a net weight of 0,025 kg, the discs fit standard 25 mm filter holders used in syringe, vacuum or manifold filtration setups. Produced by Berrytec, these membranes combine the inertness and broad chemical compatibility of PTFE with practical handling characteristics suited to buffer preparation, sample clean-up and general laboratory filtration tasks. Their compact format and consistent pore structure support reproducible results in quality-control, environmental and research laboratories where reliable removal of particulates from aqueous media is required.

Questions about PTFE hydrophilic membrane disc filter 25mm, 3µm
What is this article?
PTFE hydrophilic membrane disc filter 25mm, 3µm 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.
