Methods for mixing a fluid with foldable impellers

A method of mixing a fluid includes at least partially unfolding a collapsible bag bounding a compartment, the collapsible bag containing in the compartment at least a portion of an elongated drive line or drive shaft and an impeller secured to the drive line or drive shaft, the impeller including a plurality of impeller blades that are pivotable relative to the drive line or drive shaft, at least one of the plurality of impeller blades being in a collapsed position. A fluid is delivered into the compartment of the collapsible bag. The drive line or drive shaft is then rotated so as to rotate the impeller within the compartment and mix the fluid therein, the at least one of the plurality of impeller blades pivoting from the collapsed position to an expanded position as the impeller is rotated within the compartment.

Systems for cell culture scaling

The present set of embodiments relate to a bioproduction system, method, and apparatus for creating a scalable bioreactor system. Specifically, the present set of embodiments enable the determination of bioreaction performance characteristics of a commercial scale by matching operational parameters between a small test scale bioreaction to that of a commercial scale bioreaction. The system and methods do not rely on simply making bioreactor apparatuses across scales the same dimensionally which would not account for differences in fluid dynamic properties between very small to very large volumes, but requires tuning of a variety of systems (mixing assembly, sparger system, and headspace airflow system) in conjunction with one another to achieve predictive outcomes.
