Polytetrafluoroethylene (PTFE), a strong, tough, waxy, nonflammable synthetic resin produced by the polymerization of tetrafluoroethylene. Known by such trademarks as Teflon, Fluon, Hostaflon, and Polyflon, PTFE is distinguished by its slippery surface, high melting point, and resistance to attack by most chemicals.
High-Temperature PTFE PipeNipples and Pipe for Chemicals. This PTFE pipe can withstand a wider temperature range than any of our other plastic pipe for chemicals. It is commonly used in high-purity chemical flow processes, such as semiconductor and clean room applications.
Jul 28, 2021 · - Filtration Apparatus is compatible with 42-60mm membrane filter paper. - Nylon 66 Filter Membranes, diameter of 50mm/ 2.0inch, used for most filtrations of organic solutions and water solutions. - Commonly used in industrial and academic laboratories for filtering particles, bacteria and other substances.
Aervent cartridges have a 0.2µ PTFE membrane and are used in pharmaceutical applications where it is critical to use a phobic filter that has proven bacterial and viral retention capabilities. Common applications for Aervent are fermentation air applications, bioreactor inlet and outlet filtration and sterile process gases.
Nov 04, 2004 · Millipore produces a diverse collection of syringe-driven filter units – the Millex™ range. The devices are plastic disposable filters fitted with female Luer-Lok™ inlets and Luer-slip outlets. The filters are available in four different sizes (4mm, 13mm, 25mm and 33mm) and a range of different membrane types are available (PVDF, PES
MilliporeSigma™ Fluoropore™ PTFE Membrane Filters . Hydrophobic membrane with laminated backing for easier handling $216.50 - $989.50 Specifications. For Use With
The membrane will then allow bulk flow of water for as long as the pore remain water filled. If the membrane is allowed to dry (i.e. air enters the pores), then it must be pre-wet with a low surface tension fluid again prior to use with water. Hydrophobic membrane filters are typically used with compatible non-aqueous fluids.
Mar 01, 2006 · Millipore, a maker of purification systems used in drug manufacturing, has expanded its range of hydrophilic Polytetrafluoroethylene (PTFE) membranes, enabling it to offer filters for virtually all solvents, acids, and alkaline solutions.
use high-performance liquid chromatography coupled with tandem mass spectrometry. Resistant to most chemical and microbial conventional treatment technologies. Most common groundwater treatment method is extraction and filtration through granular activated carbon filters.

Increased porosity of e-PTFE membranes causes an increase in bacteria migration and tissue ingrowth within the porous membrane. Another PTFE membrane known as non-expanded and dense/non-porous PTFE (n-PTFE) can be used; n-PTFE has a smooth outward face which can prevent tissue ingrowth, but this can ultimately lead to poor socket flap adhesion
