Teflon®* PTFE Chemical Compatibility Chart: Check the chemical compatibility of Teflon® and PTFE with various chemicals, solvents, alcohols and other products. Polytetrafluoroethylene (PTFE) is very non-reactive and is often used in containers holding reactive and corrosive chemicals. According to DuPont, its melting point is 600 K (327 °C;
Fluoropore membranes provide broad chemical compatibility, high flow rates and consistency. (Please note that catalogue numbers containing "FHUP" are unlaminated, or produced without a backing.) Our Omnipore membrane is a hydrophilic PTFE membrane that is compatible with virually all solvents, acids, and alkaline solutions.

There are so many solvents and syringe filter/membrane materials that it can be tough to remember which combinations are safe and which are corrosive. These tables show the compatibilities between 5 materials (CA, nylon, PES, PTFE, and PVDF) and 75 common solvents (including acids, alcohols, and nitrogen solvents). Send Inquiry.
Nylon membrane 0,2 25 - 100 514-0066 0,45 25 - 100 514-0067 PP membrane These polyvalent filters are designed for the preparation of mixed samples. They fulfil a broad range of chemical compatibility for aqueous/organic mixtures. PTFE membrane These PTFE membranes are designed for filtration of corrosive gases and organic solvents.

Polytetrafluoroethylene (PTFE) Membrane. Hydrophobic, highly inert, and durable, PTFE is a popular material with a wide operating temperature range and resistance to the damaging effect of many chemicals. When should you use it? DO USE: for filtering solvents and other aggressive chemicals, such as acetone and DMSO.
Choose a filter or membrane based on: 1) Chemical compatibility of the membrane and housing with your sample matrix. 2) Size and amount of particulates in the sample. 3) Potential interactions (binding) between the membrane and sample components. 4) Special considerations such as requirement for prefilter or inorganic ion certification.
FEP / PFA / Teftek® Chemical Compatibility PTFE, FEP, PFA and Teftek® explained PTFE is part of a closely related family of fluoropolymers. At times, it is mistaken that PTFE is the one and only fluoropolymer, when FEP, ... Acetate Solvents Acetic Acid <40% <200°F (93°C) Acetic Acid <5% <200°F (93°C)
The definition of solvent compatibility for Millipore products differs from that used in determining the ratings given in published compatibility tables. Such tables are generally concerned with chemical attack and significant losses in strength and/or dimensional changes. A top designation, for example, might be designated for solvent-polymer
