A mixing apparatus including a kinetic energy source, a mixing tank, a pivot guide, and transfer shaft is used to drive a mixing paddle through a circular path within a tank without substantial shaft rotation. Sleeved and sleeveless mixing paddles are provided in combination with sealable mixing tanks. A volumetric compensation system responsive to tank wall deflection is used to maintain the internal volume of a mixing tank within predetermined limits. One mixing apparatus includes multiple mixing shafts and paddles coupled to at least one kinetic energy source. Methods for fabricating sleeved paddle-containing mixing apparatuses are further provided.

1. A volumetric compensation system adapted for use with (i) a hollow mixing tank that includes at least one tank wall bounding an internal volume and comprising a flexible tank wall material imparting pressure-dependent variable internal volume character to the mixing tank, and (ii) a mixing element adapted to move within the internal volume, wherein the volumetric compensation system comprises: a contactor element arranged to generate an output signal responsive to position or deflection of the at least one tank wall;an actuatable tank inlet arranged to selectively admit fluid to the hollow mixing tank responsive to generation of the output signal, anda filter medium in fluid communication with the actuatable tank inlet, wherein the filter medium is adapted to inhibit passage of biological contaminants into the internal volume. 2. The volumetric compensation system of claim 1, being adapted to maintain the internal volume of the mixing tank within predetermined limits. 3. The volumetric compensation system of claim 1, being free of any pressure-sensing element. 4. The volumetric compensation system of claim 1, wherein the fluid comprises pressurized gas. 5. The volumetric compensation system of claim 1, further comprising a plunger adapted to move responsive to tank wall position or deflection, wherein the plunger is coupled to the contactor element. 6. The volumetric compensation system of claim 1, further comprising a selectively operable drain. 7. The volumetric compensation system of claim 1, wherein the flexible tank wall material comprises a polymeric film. 8. The volumetric compensation system of claim 1, wherein the mixing tank is supported by an external container. 9. A mixing apparatus comprising: a hollow mixing tank having at least one tank wall bounding an internal volume and comprising a flexible tank wall material imparting pressure-dependent variable internal volume character to the mixing tank;a mixing element adapted to move within the internal volume; anda volumetric compensation system adapted to maintain the internal volume of the mixing tank within predetermined limits. 10. The mixing apparatus of claim 9, wherein the volumetric compensation system is responsive to tank wall deflection. 11. The mixing apparatus of claim 9, being free of any pressure-sensing element. 12. The mixing apparatus of claim 9, wherein the flexible tank wall material comprises a polymeric film. 13. The mixing apparatus of claim 9, wherein the volumetric compensation system is adapted to maintain a sterile environment within the internal volume. 14. The mixing apparatus of claim 9, wherein the volumetric compensation system comprises a source of pressurized gas, an actuatable tank inlet in selective fluid communication with a source of pressurized gas, and a tank outlet. 15. The mixing apparatus of claim 14, wherein the volumetric compensation system comprises a filter medium in fluid communication with the actuatable tank inlet, wherein the filter medium is adapted to eliminate inhibit passage of biological contaminants from the any gas supplied from the source of pressurized gas through the tank inlet to into the internal volume. 16. The mixing apparatus of claim 9, wherein the volumetric compensation system comprises a plunger in at least intermittent contact with the at least one tank wall, and wherein the plunger is adapted to move responsive to tank wall deflection. 17. The mixing apparatus of claim 9, wherein the volumetric compensation system comprises a contactor element arranged to generate an output signal responsive to position or deflection of the at least one tank wall. 18. The mixing apparatus of claim 9, wherein the mixing tank has an interior and an integral sleeve protruding into the interior, the sleeve having at least one exterior sleeve wall and defining a cavity containing a least a portion of the mixing element, wherein the internal volume is defined by the at least tank wall and the at least one exterior sleeve wall, and wherein the integral sleeve serves as an isolation barrier between the internal volume and the mixing element. 19. The mixing apparatus of claim 18, wherein the mixing element comprises a mixing paddle having a widened paddle portion that is substantially wider than a nominal cross-sectional diameter or width of a support rod or shaft associated with the paddle, wherein the mixing paddle is arranged to be driven by a kinetic energy source through a defined path at a nonzero angle relative to a central axis of the tank without continuous rotation of a support rod associated with the paddle. 20. The mixing apparatus of claim 9, further comprising an external container disposed around the mixing tank.
