Sartorius, DFB020L, Flexsafe® RM 20 L Basic (5 pcs)

Sartorius Flexsafe RM 20 L Basic bags provide disposable cultivation chambers for Biostat RM rocking-motion bioreactors. Each bag has a nominal 20 L capacity and supports a 2–10 L working volume for compatible cell-culture and seed-train workflows. Rocking motion generates mixing without a conventional stirred-tank impeller, offering a low-shear environment for suitable mammalian and other cultured cells. The Basic configuration contains no integrated pH or dissolved-oxygen sensor and no screw cap. Its S80 polyethylene film is supplied gamma-irradiated, with a hydrophobic gas filter and connections including Luer lock, MPC, and needle-free sampling access. The bags are suitable for development and scale-up programs where disposable fluid contact surfaces simplify changeovers. One order contains five bags, not a complete Biostat RM instrument or controller.
