Description
PORA TE membrane filters are white polytetrafluoroethylene (PTFE) membrane filters with a pore size of 3,00 µm and a diameter of 100 mm. These PORAFIL TE discs serve laboratory membrane filtration tasks that require a defined pore width in a PTFE matrix. Each pack contains 25 pieces, a practical quantity for ongoing analytical or preparative work. The white membrane colour facilitates visual control when loading holders and funnels. At 100 mm diameter, the filters align with standard laboratory filtration equipment of matching size. The 3,00 µm pore size supports retention of larger particles while allowing filtrate passage under suitable conditions. Construction material is polytetrafluoroethylene (PTFE), as specified for the PORAFIL TE range from manufacturer Macherey-Nagel. The membranes are supplied non-sterile and are therefore intended for general laboratory filtration rather than aseptic processing. Compact packaging keeps the 25 discs ready for bench use. Laboratories that specify PTFE membrane filters at 3,00 µm and 100 mm can use this format in sample preparation and clarification workflows where controlled pore geometry is required.
This article is part of Membrane filters, in Filtration.

Questions about PORA TE, white, PW:3,00 µm, d: 100 mm
What is this article?
PORA TE, white, PW:3,00 µm, d: 100 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.
