Description
PORA TE membrane filters are white polytetrafluoroethylene (PTFE) membrane filters with a pore size of 3,00 µm and a diameter of 220 mm. These PORAFIL TE discs address laboratory membrane filtration needs that call for a large-format PTFE membrane with a defined pore width. Each pack contains 10 pieces, practical for filtration setups that employ 220 mm equipment. The white colour of the membrane supports clear visual handling when placing discs in holders. At 220 mm diameter, the filters match large laboratory filtration hardware of this size. The 3,00 µm pore size enables controlled retention of coarser particles while permitting filtrate flow under appropriate conditions. Material of construction is polytetrafluoroethylene (PTFE), as specified for the PORAFIL TE range from manufacturer Macherey-Nagel. The product is supplied non-sterile and is therefore intended for general laboratory filtration rather than aseptic lines. Ten discs per pack provide a convenient stock unit for repeated large-diameter filtrations. Laboratories that require white PTFE membrane filters at 3,00 µm and 220 mm can use this format in sample preparation and clarification work where the stated geometry and material are specified.
This article is part of Membrane filters, in Filtration.

Questions about PORA TE, white, PW:3,00 µm, d: 220 mm
What is this article?
PORA TE, white, PW:3,00 µm, d: 220 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.
