These cellulose Ester (CE) membrane offers the largest range of concise for desalting, isolating ionic species and macromolecular purifications which is supplied wet in 0,05 % or 0,1% sodium azide.

• Superior chemical compatibility and temperature tolerance
• Rigidly controlled porosity for better selectivity and separations
• Ultrapure with no trace heavy metals & sulfides
• Does not interfere with molecular activity and function
• No glycerin removal or pretreatment required

Tubing is more sensitive to harsh conditions and solvents and generally tolerates weak or dilute acids, bases and mild alcohols because exposure to most organic solvents may damage CE membranes. These membranes are to be used with pH 2 to 9 and temperature 4 to 37 °C.
