Beschreibung
PTFE membrane filter discs, hydrophobic, 25 mm, 1,00 µm are unsupported membrane discs intended for laboratory filtration tasks that demand chemical resistance and non-wetting behaviour. Fabricated from polytetrafluoroethylene without a support structure, these hydrophobic discs retain particles at a nominal pore size of 1,00 µm while remaining compatible with aggressive organic media and gas-phase applications where aqueous wetting is undesirable. The 25 mm diameter format fits standard filter holders used in sample preparation, analytical chemistry and process monitoring. Packaged as 100 pieces, the discs provide a convenient stock quantity for routine laboratory use. Their unsupported construction minimises extractables and simplifies handling when a pure PTFE membrane is required. Available from manufacturer Berrytec, these hydrophobic PTFE membrane filter discs support workflows that need reliable particle retention together with broad solvent compatibility. They are well suited to organic solvent clarification, venting and other filtration steps in which a hydrophobic, chemically inert membrane is preferred over hydrophilic alternatives.
This article is part of Sintered glass filter plates & discs, in Filtration.

Questions about PTFE hydrophobic membrane disc filter 25mm, 1,00µm
What is this article?
PTFE hydrophobic membrane disc filter 25mm, 1,00µm is the article on this page. Luminix Health distributes Berrytec for laboratory use. It sits in Sintered glass filter plates & discs, inside Filtration, in Verbrauchsmaterialien.
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.
