Description
PTFE membrane filter discs hydrophilic 50 mm, 0,22 µm are hydrophilic polytetrafluoroethylene membrane discs for laboratory filtration applications that specify this diameter and pore size. Each disc has a 50 mm diameter and a 0,22 µm pore rating, providing a defined hydrophilic PTFE filtration surface for sample preparation and clarification steps. The product is supplied in a pack of 100 pieces with a net weight of 0,1 kg and a gross weight of 0,1 kg. Packaging volume is 0,00039 m³, accompanied by outer dimensions of 0,025 m height, 0,13 m width and 0,12 m depth. These hydrophilic PTFE membrane filter discs are available from manufacturer Berrytec and list China as country of origin. They are intended for general laboratory use wherever a 50 mm hydrophilic PTFE membrane with 0,22 µm porosity is required. No additional sterility, purity grade or performance claim is stated beyond the material, hydrophilic character, diameter and pore-size information supplied. The discs fall under standard laboratory filtration classification and can be integrated into existing filter-holder workflows that call for this membrane format and specification.
This article is part of Membrane filters, in Filtration.

Questions about PTFE hydrophilic membrane disc filter 50mm, 0,22µm
What is this article?
PTFE hydrophilic membrane disc filter 50mm, 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.
