Description
PTFE membrane filter discs hydrophobic 110 mm, 0,45 µm are specialised laboratory filtration media intended for demanding solvent and gas applications. These pure polytetrafluoroethylene discs are supplied without any support structure, delivering inherent hydrophobicity and broad chemical resistance. The 110 mm diameter fits common filter holders used in analytical and preparative work, while the 0,45 µm pore size supports reliable particle retention in non-aqueous systems. A pack of 50 pieces provides practical laboratory stock for routine filtration tasks. Produced by manufacturer Berrytec, the unsupported PTFE construction minimises extractables and maintains high flow characteristics with aggressive media. Typical uses include clarification of organic solvents, venting of vessels, and sample preparation where conventional membranes would swell or degrade. The discs combine thermal stability with inertness, making them suitable for research, quality-control and process-development environments that require reproducible, contamination-free results. Compact packaging and a net weight of 0,1 kg facilitate easy storage and handling in busy laboratory settings.

Questions about PTFE hydrophobic membrane disc filter 110mm, 0,45µm
What is this article?
PTFE hydrophobic membrane disc filter 110mm, 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 Consommables.
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.
