    摘要： An impeller is usable in a variable diameter bioreactor having multiple vessel sections of successively increasing or decreasing volume. The impeller includes an impeller blade extending along an impeller blade axis between first and second axial ends and having opposed impeller blade faces, an impeller blade leading edge, and an impeller blade trailing edge. Each of the leading and trailing edges defines a helix or spiral between the axial ends of the impeller blade. In certain arrangements, the impeller blade is one of at least two impeller blades joined together along an impeller shaft extending axially along the impeller blade axis mentioned, and the helix or spiral has a pitch approximately equal to one half of a length between the first and second axial ends.

    摘要： A system for continuously making-down a dry powder material is provided. The system may include a liquid supply system, a material feed system, a vessel, a filter, and an agitator. The vessel may receive a continuous supply of liquid from the liquid supply system and a continuous supply of dry powder from the material feed system. The liquid and material may be discharged continuously from the vessel. A filter may sealingly extend across the outlet to filter the solution exiting the vessel. The filter may include an upstream surface in contact with the inner volume of the vessel. The agitator may be disposed within the vessel and may be configured to agitate the contents of the vessel. The agitator may include a wiping member configured to contact the upstream surface of the filter while agitating the contents.

    摘要： Disclosed herein is a system for creating an injectable and flowable cold slurry, the system comprising a housing; a mount operatively connected to the housing configured to accept a container; a first motor configured to move the mount from a first position to a second position; a second motor; and a drive shaft in communication with the second motor, wherein the drive shaft is configured to rotate to cause an internal volume of the container to be transformed into the injectable and flowable cold slurry.
