Description
PTFE membrane filter discs hydrophobic 25 mm, 3,00 µm are plain laboratory membrane filters supplied as unsupported discs. Manufactured from polytetrafluoroethylene, they combine a hydrophobic surface character with a defined pore size of 3,00 µm and a diameter of 25 mm. The membranes are produced without a support structure, providing a pure PTFE filtration layer free of backing materials. Each pack contains 100 pc(s) and has a net weight of 0,025 kg. These discs from manufacturer Berrytec are intended for routine laboratory filtration where chemical resistance and a hydrophobic PTFE membrane are required. The unsupported construction allows direct membrane contact without intermediate layers. The 25 mm format fits standard small-scale filter holders and assemblies commonly used in analytical and preparative work. Consistent disc geometry supports reproducible handling across the pack. Hydrophobic PTFE membranes of this type are selected for solvent-compatible filtration steps, sample clarification and related laboratory procedures that benefit from an unsupported membrane. The combination of 3,00 µm pore size, hydrophobic PTFE and absence of support structure defines this specification for everyday lab use.
This article is part of Sintered glass filter plates & discs, in Filtration.

Questions about PTFE hydrophobic membrane disc filter 25mm, 3,00µm
What is this article?
PTFE hydrophobic membrane disc filter 25mm, 3,00µm is the article on this page. Luminix Health distributes Berrytec for laboratory use. It sits in Sintered glass filter plates & discs, inside Filtration, in 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.
