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.
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.

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.
InnoSep™ Membrane Filters. Nylon • Naturally hydrophilic • Wide chemical compatibility range, organic solvent resistance (except acids and bases) • Internally supported similar stability to PTFE. Polytetrafluoroethylene (PTFE) • Naturally hydrophilic • Compatible with strong acids and aggressive solvents
To compare between all the common membranes and solvents, review the chemical compatibility chart in our guide to laboratory membrane filtration principles and chemical compatibility. You might also find it useful to follow our quick reference chart (below) or try our filter selector tool to find your membrane filter fast.
RC also has a broad solvent compatibility. Together with PTFE, RC is a useful general-purpose option to have on-hand. Extractables are a common symptom of membrane-sample incompatibility and affect sensitive downstream analytical techniques, such as ultra-high-performance liquid chromatography (UHPLC) and high-performance liquid chromatography
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
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
