Description
PORA TE membrane filter is a white polytetrafluoroethylene (PTFE) disc with a pore size of 1,00 µm and a diameter of 50 mm for laboratory membrane filtration. This PORAFIL TE membrane is suited to particulate retention, clarification and solvent-compatible work where the chemical resistance of PTFE is beneficial. The 50 mm diameter provides a practical filtration area for standard holders used in research, quality control and preparative procedures. Each pack contains 50 pieces, supporting efficient replenishment of routine laboratory stocks. The white membrane surface simplifies visual handling and correct seating in the filter assembly. Non-sterile supply aligns with general laboratory practice; any sterilisation requirements are applied by the user if needed. Consistent pore rating at 1,00 µm supports reproducible separation performance across successive runs. These filters are available from manufacturer Macherey-Nagel as part of the PORAFIL TE range. PTFE construction combined with the stated 50 mm format makes the discs a dependable choice for demanding sample matrices and everyday membrane filtration tasks.
This article is part of Membrane filters, in Filtration.

Questions about PORA TE, white, PW:1,00 µm, d: 50 mm
What is this article?
PORA TE, white, PW:1,00 µm, d: 50 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.
