Description
PTFE membrane filter discs hydrophilic 47 mm, 0,22 µm serve as laboratory filtration media for particle retention and sample clarification. These hydrophilic polytetrafluoroethylene discs unite the chemical resistance of PTFE with enhanced aqueous wettability, enabling reliable filtration of water-based solutions, buffers and compatible organic mixtures. Featuring a 47 mm diameter and 0,22 µm pore size, they support fine to medium filtration steps typical of analytical and research laboratories. Packs of 100 pieces provide convenient stock for routine use, with a net weight of 0,1 kg. Offered by manufacturer Berrytec, the discs fit standard 47 mm filter holders used in sample preparation, reagent clarification and general liquid processing. The hydrophilic character lessens the need for alcohol pre-wetting in many aqueous applications, simplifying daily protocols. These membrane filter discs deliver a dependable consumable option where PTFE inertness and a defined 0,22 µm pore structure are essential for consistent laboratory performance.

Questions about PTFE hydrophilic membrane disc filter 47mm, 0,22µm
What is this article?
PTFE hydrophilic membrane disc filter 47mm, 0,22µm is the article on this page. Luminix Health distributes Berrytec for laboratory use. It sits in Sintered glass filter plates & discs, inside Filtration, in Lab consumables.
A sintered glass filter is a disc of fused glass particles with a porosity grade, often 0 to 5, from coarse to fine. It is cleaned and reused. The porosity number, not a micrometre guess, is the specification. Hydrofluoric acid and strong alkali attack the glass.
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.
