Description
PORAFIL TE membrane filter is a white polytetrafluoroethylene (PTFE) disc with a pore size of 0,20 µm and a diameter of 47 mm for laboratory membrane filtration. These hydrophobic PTFE membranes support sample clarification, solvent handling and fine particulate retention where broad chemical resistance is required. Each pack contains 50 filters sized for standard 47 mm holders used in analytical chemistry, environmental testing and quality-control workflows. The TE series from manufacturer Macherey-Nagel combines a defined 0,20 µm pore structure with the inert character of PTFE, making the discs suitable for many organic solvents and aggressive media when applied according to established filtration practice. The white surface aids visual assessment of retained material during routine work. Non-sterile supply fits general laboratory filtration steps rather than aseptic processing. Compact packaging and consistent geometry help laboratories maintain reproducible filtration setups across repeated sample batches requiring a 0,20 µm cut-off in the widely used 47 mm format.
This article is part of Membrane filters, in Filtration.

Questions about PORA TE, white, PW:0,20 µm, d: 47 mm
What is this article?
PORA TE, white, PW:0,20 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.
