A fluid mixing system that can be used as a bioreactor or fermentor can include a stand and a support housing pivotably mounted to the stand. The support housing bounds a chamber into which a container assembly is removably disposed. The container assembly includes a flexible bag bounding a compartment adapted to hold a fluid and a mixing element disposed within the compartment. The support housing can be tilted relative to the stand for ease in insertion of the container assembly. The support housing can also be repeatedly rocked relative to the stand form mixing fluid within the container assembly.

1. A fluid mixing system comprising: a support housing bounding a chamber;a flexible container disposed within the chamber of the support housing, the flexible container being adapted to hold a fluid;means for mixing a fluid contained within the flexible container by repeatedly moving the support housing and the flexible container contained therein; andmeans for mixing a fluid contained within the flexible container without movement of the support housing, the means comprising a mixing element movably disposed within the flexible container. 2. The fluid mixing system as recited in claim 1, wherein the means for mixing the fluid contained within the flexible container by repeatedly moving the support housing comprises: a stand, the support housing being pivotably mounted to the stand so that the support housing can rock relative to the stand; anda motor that causes repeated rocking of the support housing relative to the stand. 3. The fluid mixing system as recited in claim 1, wherein the mixing element comprises an impeller. 4. The fluid mixing system as recited in claim 3, wherein a vertical height and an angle of orientation of the impeller within the flexible container can be adjusted. 5. The fluid mixing system as recited in claim 1, further comprising a gas sparger at least partially disposed within the flexible container. 6. The fluid mixing system as recited in claim 1, wherein the flexible container is comprised of one or more sheets of polymeric film. 7. The fluid mixing system as recited in claim 1, further comprising: the support housing having a floor and an encircling sidewall upstanding therefrom that at least partially bound the chamber; anda drain line is coupled with the flexible container at a location within 15 cm from the floor of the support housing but spaced apart from the floor of the support housing. 8. The fluid mixing system as recited in claim 1, wherein the support housing comprises a cylindrical sidewall that encircles the chamber and extends between a first end and an opposing second end. 9. The fluid mixing system as recited in claim 8, wherein the means for mixing a fluid contained within the flexible container by repeatedly moving the support housing and the flexible container contained therein causes the support housing to pivot about a rotational axis, the rotational axis being centrally disposed between the first end and the opposing second end of the cylindrical sidewall. 10. The fluid mixing system as recited in claim 9, further comprising: the chamber of the support housing having a central longitudinal axis that extends through the chamber between the first end and the opposing second end; andthe means for mixing a fluid contained within the flexible container by repeatedly moving the support housing and the flexible container contained therein comprises the support housing being pivotably mounted to a stand so that the support housing can pivot about a rotational axis, the rotational axis intersecting with the central longitudinal axis. 11. The fluid mixing system as recited in claim 1, further comprising: the support housing comprising: a sidewall that encircles the chamber and extends between a first end and an opposing second end;an access opening formed at the first end of the sidewall;a floor disposed at the second end of the sidewall, a longitudinal axis extending through the chamber so as to pass through the floor and the access opening; andthe means for mixing a fluid contained within the flexible container by repeatedly moving the support housing and the flexible container contained therein comprising the support housing being pivotably mounted to a stand so that the support housing can be pivoted between: a forward tilt position wherein the longitudinal axis is at least +5° from vertical; anda rearward tilt position wherein the support housing is tilted in a direction opposite the forward tilt position and the longitudinal axis is at least −5° from vertical. 12. A fluid mixing system comprising: a support housing bounding a chamber;a flexible container disposed within the chamber of the support housing, the flexible container being adapted to hold a fluid;means for mixing a fluid contained within the flexible container by repeatedly moving the support housing and the flexible container contained therein, the means comprising a shaker table on which the support housing is disposed, the shaker table being configured to reciprocally move back and forth in one or two dimensions in a horizontal plane; andmeans for mixing a fluid contained within the flexible container without movement of the support housing.
