In an embodiment, an apparatus includes a disposable and flexible mixing tank, configurable as a bag, having a sealed sleeve therein for arrangement of a mixing device. The volume of the mixing tank is defined by an inner wall of the mixing tank and an inner wall of the sleeve. The mixing tank may be used to mix, store, reconstitute and/or dispense materials therein. Draining of a mixture may be aided with pressurized gas. Heating or cooling of the contents of a mixing tank may be accomplished with a thermal exchange fluid disposed within a thermal exchange vessel and in thermal communication with the tank.
