Abstract: A powder mixing system (12) includes a conduit (40) having a first end and an opposing second end, the conduit bounding a passage; a fluid pump (80) fluid coupled with the conduit, the fluid pump being configured to pump a liquid through the passage of the conduit; and a tubular transfer member (190) in fluid communication with the conduit, the transfer member being configured to couple with a powder bag housing a powder. The mixing system further including: (1) an eductor coupled to the transfer member and disposed in-line with the conduit so that the liquid pumped through the conduit also passes through the eductor; and/or (2) an auger assembly comprising an auger blade, at least a portion of the auger assembly being rotatably disposed within the transfer member.

Abstract: 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.

Abstract: A mixing system includes a housing and a motor mount disposed on the housing and having a passage extending therethrough. A dive motor is coupled with the motor mount for selectively rotating the motor mount relative to the housing. A rotational assembly includes a hub having a passageway extending therethrough and a casing at least partially encircling the hub, the hub being rotatable to the casing. The rotational assembly is removably coupled to the housing so that the passageway of the hub aligns with the passage of the motor mount.

Abstract: A sparger includes a body bounding a compartment. A tubular port or tube is coupled with the body. The tubular port or tub bounds a passage that communicates with the compartment of the body. At least a portion of the body includes of a first sparging sheet. The first sparging sheet includes a flexible sheet of a gas permeable material such that a gas passing into the compartment of the body through the passage can exit the compartment by permeating through the first sparging sheet.

Abstract: A system for mixing a liquid solution or suspension includes a collapsible container having an interior surface bounding a compartment, the compartment being adapted to hold a liquid solution or suspension.
