The Mobius CellReady 3L Bioreactor is a ready-to-use three-liter bioreactor that demonstrates all the benefits typically associated with single-use processing, while incorporating standard design features familiar to users already using benchtop, stirred-tank bioreactors. Designed to replace traditional glass benchtop bioreactors, the CellReady 3L Bioreactor has a standard stirred-tank format for use in development and optimization of cell culture processes. This vessel design provides a higher degree of predictability during process scale-up when compared to formats utilizing alternative vessel designs and agitation methods. It features a universal design, ensuring compatibility with most benchtop bioreactor control systems. By eliminating time-consuming steps associated with cleaning, assembly, and sterilization, the CellReady 3L bioreactor significantly reduces the turnaround time typically associated with glass bioreactors.
