Polyethersulfone membrane
The robust polyethersulfone membrane (PESU) is a polymer, stable within a broad pH (1 to 14) and temperature range. Membrane regeneration and depyrogenation is accomplished by using (1 N) NaOH at elevated temperatures. Cassettes are stored in 0,1 N NaOH.

• Low hold-up volume and low protein-binding
• Wide pH and temperature range
• High flow rates
• Silicone sealing compound

Hydrosart® membrane
The cellulose-based membrane is stable polymer, which is compatible with a wide range of chemical agents and stable within a broad pH range. It is also an extremely hydrophilic and neutral membrane, making it non-protein binding and virtually nonfouling. It exhibits extremely high and consistent flux rates. Membrane regeneration, and depyrogenation is accomplished by using (1 N) NaOH at elevated temperatures. Cassettes are stored in 0,1 N NaOH.
