Description
PTFE membrane filter discs hydrophilic 47 mm, 0,45 µm are laboratory filtration media designed for particle retention and sample clarification. These hydrophilic polytetrafluoroethylene discs combine PTFE chemical resistance with improved aqueous wettability, supporting filtration of water-based solutions, buffers and compatible solvent systems. With a 47 mm diameter and 0,45 µm pore size they are well suited to general clarification and medium filtration steps in analytical and research settings. Each unit pack holds 100 pieces for everyday laboratory consumption and carries a net weight of 0,1 kg. Supplied by manufacturer Berrytec, the discs are intended for use in standard 47 mm filter holders common to sample preparation, reagent clean-up and routine liquid processing. The hydrophilic surface reduces pre-wetting steps in many aqueous protocols, helping maintain efficient workflows. These membrane filter discs provide a practical consumable choice whenever PTFE inertness and a defined 0,45 µm pore structure are required for reproducible laboratory filtration results.

Questions about PTFE hydrophilic membrane disc filter 47mm, 0,45µm
What is this article?
PTFE hydrophilic membrane disc filter 47mm, 0,45µm is the article on this page. Luminix Health distributes Berrytec for laboratory use. It sits in Sintered glass filter plates & discs, inside Filtration, in Consommables.
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.
