Description
PORAFIL TE membrane filter is a white polytetrafluoroethylene (PTFE) laboratory membrane with a pore size of 0,20 µm and a diameter of 100 mm. This disc-format filter is part of the PORAFIL TE range and is intended for membrane filtration work in analytical, quality-control and research laboratories. PTFE construction suits applications where the chemical resistance of the membrane material is required, while the 0,20 µm pore width defines the retention characteristic of the disc. The membranes are supplied white and non-sterile, in line with the stated specification for general laboratory handling. Each pack contains 25 pieces, a practical quantity for recurring filtration steps on compatible 100 mm holders and related apparatus. The product comes from manufacturer Macherey-Nagel within the established PORAFIL membrane filter line. Clearly stated diameter, pore size and material help users select the correct membrane for sample clarification, solvent handling compatible with PTFE, or particulate removal workflows. Consistent disc geometry supports straightforward loading into standard filter hardware used across many lab setups.
This article is part of Membrane filters, in Filtration.

Questions about PORA TE, white, PW:0,20 µm, d: 100 mm
What is this article?
PORA TE, white, PW:0,20 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.
