- For solvents like NMP, DMSO and DMF a stabilized membrane SolSep NF010206S is available.
- For water containing substantial amounts of solvent, SolSep NF090101 can be used.
PDMS membrane
A well-known type of solvent resistant membrane is the PDMS membrane. PDMS (poly-dimethyl siloxane) is a specific type of silicon. Nanofiltration and pervaporation using PDMS membranes is described in many literature references. SolSep PDMS membranes have a solvent resistant support which broadens their application range.
