Description
Hydrophobic PTFE membrane filter 0,22 µm, 47 mm is a white, unsterile disc membrane for laboratory filtration where a hydrophobic polytetrafluoroethylene surface is preferred. The 0,22 µm pore size and 47 mm diameter suit standard filter holders used for gas, solvent, and aggressive-chemical handling when a PTFE membrane is specified. Hydrophobic PTFE is valued for broad chemical compatibility and low extractables in many organic and corrosive media workflows. Each unit pack provides 100 pc(s), supporting shared laboratory use and recurring preparation steps. Offered by manufacturer filtraTECH, the discs are supplied white and unsterile for procedures that do not call for pre-sterilised filters. Typical applications include solvent filtration support, venting and gas-related filtration tasks, and sample work-up where aqueous wetting is not required. The familiar 47 mm format simplifies mounting in vacuum or pressure hardware and keeps storage and inventory straightforward for analytical, process-support, and research laboratories working with non-aqueous systems.
This article is part of Membrane filters, in Filtration.

Questions about Hydrophobic PTFE membrane filter 0,22µm, 47 mm
What is this article?
Hydrophobic PTFE membrane filter 0,22µm, 47 mm is the article on this page. Luminix Health distributes filtraTECH 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.
