Sartorius, DFO020L, Flexsafe® RM 20 L Optical (5 pcs)

Flexsafe® RM Optical is a sterile single-use rocking-motion bioreactor bag designed for cultivation on compatible Biostat® RM 20/50 L equipment. This 20 L configuration incorporates pre-calibrated optical pH and dissolved oxygen sensors, supporting continuous monitoring without a reusable probe contacting the culture. The stated working-volume range is 2–10 L. The polyethylene-film bag supports low-shear wave mixing for mammalian cells and selected other culture processes and can be integrated into qualified instrument-control workflows. This version does not include a screw cap and is supplied as five sterile bags. The assembly provides a disposable cultivation chamber with appropriate ports and gas filters; its nominal bag capacity should not be confused with the smaller recommended working volume.
