Biologically inert and ultra-pure, Biotech Cellulose Ester (CE) Membrane offers the largest range of concise MWCO's (100 to 1000000 Daltons) for desalting, isolating ionic species and macromolecular purifications.

Biotech CE membrane is more sensitive to harsh conditions and solvents and generally tolerates weak or dilute acids and bases and mild alcohols with only a slight change to the MWCO. Biotech CE Tubing is available in 10 meter rolls and 1 meter length Dialysis Trial Kits.
