- For solvents like NMP, DMSO and DMF a stabilized membrane SolSep NF150506 (previous: 010206S) is available.
- For water containing substantial amounts of solvent, SolSep NF090101, NF150101 can be used.
- high (&low)pH incl. solvent (eg-biorefinery, extractions) SolSep NF090801, NF150801 are available.
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.
