A system for pumping or mixing a fluid using a rotating pumping or mixing element and various other components for use in a pumping or mixing system are disclosed.
Claims23
A mixing tank assembly for use in mixing a fluid under sterile conditions so as to avoid contamination or leakage, comprising:
- a side wall having an interior surface at least partially bounding a chamber;
- a floor disposed within or at the base of the chamber, the floor having an opening extending therethrough;
- a flexible bag disposed within the chamber so as to rest on the floor, the flexible bag having an upper portion and a substantially continuous lower portion bounding a hermetically sealed compartment capable of holding the fluid under sterile conditions;
- a mixer disposed within the compartment of the flexible bag;
- and
- a shaft having a first end for receiving the mixer.
