Description
PTFE membrane filter discs hydrophilic 142 mm, 0,22 µm are polytetrafluoroethylene membrane discs for aqueous and mixed-solvent laboratory filtration. With a diameter of 142 mm and a nominal pore size of 0,22 µm, these hydrophilic filters support sterile filtration, clarification and sample preparation of water-based and compatible organic media. The PTFE membrane combines chemical resistance with ready wettability by aqueous solutions, enabling reliable flow in analytical and preparative workflows. Packaged as 50 pieces and available from manufacturer Berrytec, the discs fit standard large-format laboratory filter holders used in research, quality control and process development. Hydrophilic character allows spontaneous wetting by water and aqueous buffers, which simplifies handling compared with untreated PTFE while retaining broad chemical compatibility. Net pack weight is 0,16 kg. These membrane filter discs provide a chemically robust filtration medium for routine laboratory applications requiring hydrophilic PTFE performance at 0,22 µm retention.
This article is part of Membrane filters, in Filtration.

Questions about PTFE hydrophilic membrane disc filter 142mm, 0,22µm
What is this article?
PTFE hydrophilic membrane disc filter 142mm, 0,22µm is the article on this page. Luminix Health distributes Berrytec 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.
