Nanoporous PEEK (Polyether Ether Ketone) Membranes are known for their excellent chemical resistance to almost any known organic solvent. These membranes are capable of separation in the nanofiltration range and resistant to nasty solvents such as N,N-dimethylformamide (DMF), tetrahydrofuran (THF), as well as an alkaline and acidic aqueous solution in a whole pH range. Moreover, Nanoporous PEEK Membranes undergo negligible aging, even under elevated temperatures.

Application note
PEEK Membranes exhibit high resistance under electrochemically harsh conditions. These membranes are typically used to separate compartments in H-Cells filled with aqueous or organic electrolytes and are ideal for organic electrosynthesis, electrolysis, fuel cells, batteries, biomolecule separation, membrane catalysis etc. The membranes are cut to the desired size using a laser. They are also available in sheets.
