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;
PTFE is the most versatile plastic in terms of chemical compatibility. Low temperature: maintains high strength, toughness and self-lubrication as low as 5°K (-268°C /-450°F) and good flexibility at 194°K (-79°C / -110°F) NOT compatible with certain alkali metals and fluorinating agents such as xenon difluoride and cobalt (III) fluoride
Intro. 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 five common syringe filter materials -- Cellulose Acetate (CA), Nylon, PES, PTFE, and PVDF -- and their compatibilities with 75 common solvents..

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.
71897. Kinesis. Remove particulate without adversely affecting your final product. Use membrane filtration for samples holding suspended solids. Highly efficient filtration of particles according to size. Complete sample filtration with the least sample loss and energy use. Filtration for HPLC sample preparation and mobile phase.
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.

Other compatibility tables may make recommendations based upon dimensional change as a function of time. This is difficult to relate to a membrane that may respond almost immediately to immersion in solvent. In addition, solvent-membrane compatibility requires additional consideration of filtration-specific factors.
