Description
PORAFIL TE membrane filter is a white polytetrafluoroethylene (PTFE) disc membrane with a pore size of 0,45 µm and a diameter of 13 mm. It is intended for laboratory membrane filtration where the chemical resistance of PTFE is required for clarifying liquids and retaining fine particulates. Each pack contains 50 pieces, a practical quantity for routine analytical and preparative work with limited sample volumes. The white TE membrane provides a uniform filtration surface at the stated pore rating and fits common small-scale filter holders used in research and quality-control laboratories. These membranes are offered from manufacturer Macherey-Nagel as part of the PORAFIL TE range for standard membrane-filter applications. The 13 mm format supports compact workflows, while the 0,45 µm pore width addresses particle removal in solvent-based and aqueous media compatible with PTFE. Filters are supplied non-sterile. Pack net weight is 0,02 kg, and the lightweight disc format simplifies bench handling and storage in busy laboratory environments that rely on consistent membrane geometry and material performance.
This article is part of Membrane filters, in Filtration.

Questions about PORA TE, white, PW:0,45 µm, d: 13 mm
What is this article?
PORA TE, white, PW:0,45 µm, d: 13 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.
