Sartorius, DFP100L--AT, Flexsafe® RM 100 L Perfusion ATF (2 pcs)

Flexsafe® RM 100 L Perfusion ATF is a single-use rocking-motion bioreactor bag configured for connection to an external alternating tangential flow (ATF) perfusion system. The assembly is used with compatible Biostat® RM hardware for low-shear mammalian-cell cultivation and process development. This 100 L nominal bag has a specified 10–50 L working-volume range and incorporates optical pH and dissolved oxygen sensors for process monitoring. The ATF connection enables cell-retention perfusion through an external module; it is distinct from RM bags with an integrated 1.2 µm perfusion membrane. The assembly uses polyethylene film and is delivered sterile. The product is supplied as two bags and supports repeated media exchange during controlled bioreactor cultivation.
