Description
PORA TE membrane filter is a white polytetrafluoroethylene (PTFE) disc with a pore size of 1,00 µm and a diameter of 25 mm for laboratory membrane filtration. This PORAFIL TE membrane is intended for particulate retention, clarification and solvent-compatible filtration steps where the chemical resistance of PTFE is advantageous. The defined pore rating supports reproducible separation performance in analytical and preparative workflows that use standard 25 mm filter holders. Each pack contains 50 pieces, suited to routine bench work in research, quality control and process laboratories. The white membrane surface facilitates visual handling and positioning during loading. Non-sterile supply matches general laboratory practice where any further sterilisation is managed by the user if required. Physical format and material choice make the discs practical for aggressive media and demanding sample matrices. These filters come from manufacturer Macherey-Nagel as part of the PORAFIL TE range. Consistent geometry at 1,00 µm pore size and 25 mm diameter supports reliable day-to-day filtration tasks without unnecessary complexity.
This article is part of Membrane filters, in Filtration.

Questions about PORA TE, white, PW:1,00 µm, d: 25 mm
What is this article?
PORA TE, white, PW:1,00 µm, d: 25 mm is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Membrane filters, inside Filtration, in Lab consumables.
A membrane filter is the disc itself, without a syringe housing. Pore size, polymer and diameter are the specification, and the disc has to sit in a holder. Gridded membranes are for counting colonies. A membrane and a filter paper of the same diameter are not interchangeable.
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.
