Description
PORA TE membrane filter is a white polytetrafluoroethylene (PTFE) disc with a pore size of 1,00 µm and a diameter of 47 mm for laboratory membrane filtration. This PORAFIL TE membrane supports particulate retention, sample clarification and solvent-compatible filtration where PTFE chemical resistance is required. The 47 mm format fits common filter holders used in analytical, quality-control and preparative applications that need a larger filtration area than smaller discs. Each pack contains 50 pieces for efficient stocking of routine bench workflows. The white membrane surface aids visual inspection during handling and assembly. Non-sterile construction is appropriate for general laboratory use when any additional sterilisation steps remain under user control. Defined pore geometry at 1,00 µm promotes consistent flow behaviour across repeated filtrations. These discs are offered from manufacturer Macherey-Nagel within the PORAFIL TE series. Material durability and the stated diameter make them practical for demanding media and everyday membrane filtration tasks in research and industrial laboratories.
This article is part of Membrane filters, in Filtration.

Questions about PORA TE, white, PW:1,00 µm, d: 47 mm
What is this article?
PORA TE, white, PW:1,00 µm, d: 47 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.
