Simplify and Intensify Cell Culture: XCell™ ATF Systems for Cell Culture Process Intensification Now Available in Single-Use Format

A finalist for the 2012 BPI Technology of the Decade Award, XCell™ ATF systems consistently yield high cell retention, concentration, and viability, enabling efficient and productive perfusion and N – 1 perfusion as well as cell banking and seed-train cell culture operations.

XCell™ ATF devices are now available in single-use format, in addition to stainless steel. The new single-use devices deliver 100% cell retention and laboratory-to-production scalability like their stainless steel counterparts but without the need for autoclave sterilization and lengthy setup times.

Figure 2: Alternating tangential flow (ATF) technology: XCell™ systems use ATF technology created by the action of a diaphragm moving upward and downward within a pump head, connected to a filter housing and attached to a bioreactor.

Features and benefits of XCell™ ATF Systems include
