Polytetrafluoroethylene (PTFE) Membrane is supported with a polypropylene (PP) scrim for easier handling. This scrim is bonded using a unique technique utilizing no bonding agent for purity, chemical compatibility and lower extractables. Hydrophobic material is effective in separating polar/nonpolar solvents. Aqueous solutions can pass after prewetting with methanolMeer tonenMinder tonen
