The invention claimed is: 1. An apparatus intended for receiving a fluid and a rotatable fluid-agitating element, comprising: a collapsible bag including an interior compartment capable of receiving and holding the fluid and the fluid-agitating element; and a roller bearing adapted for providing low-friction support for the fluid-agitating element in the interior compartment of the bag. 2. The apparatus according to claim 1, wherein the bag includes a cap-shaped receiver for receiving the fluid-agitating element that projects toward an interior compartment of the bag, thereby forming an external cavity. 3. The apparatus according to claim 1, wherein vessel includes a cup-shaped receiver that forms a cavity in communication with the interior compartment of the bag for at least partially receiving the roller bearing and the fluid-agitating element. 4. The apparatus according to claim 1, wherein the bag includes a rigid receiver that supports the fluid-agitating element. 5. A method of forming an assembly for agitating a fluid, comprising: providing a collapsible bag for receiving a magnetic fluid-agitating element; and supporting the fluid-agitating element on a roller bearing in the bag. 6. The method of claim 5, wherein the bag includes a post, the roller bearing includes an opening, and the supporting step comprises placing the post through the opening. 7. The method of claim 5, further comprising attaching the roller bearing to a rigid receiver attached to the bag. 8. The method of claim 7, wherein the rigid receiver is cap-shaped and includes a sidewall for supporting the roller bearing. 9. The method of claim 7, wherein the rigid receiver is cup-shaped and includes a cavity in communication with an interior compartment of the bag, and the method includes the step of positioning the roller bearing in the cavity. 10. An apparatus intended for receiving and agitating a fluid, comprising: a collapsible bag including an interior compartment for receiving the fluid; and a magnetic fluid-agitating element positioned in the interior compartment of the bag; wherein the bag includes a tube extending into the interior compartment and supports a roller bearing for use in rotating the fluid-agitating element in the bag. 11. The apparatus according to claim 10, wherein the bearing is exterior to the interior compartment of the bag. 12. A method of positioning a fluid-agitating element in a bag intended for receiving a fluid in need of agitation, comprising: supporting the fluid-agitating element in the vessel with a roller bearing that bodily rotates relative to the bag. 13. The method of claim 12, wherein the bag includes a post, the bearing is a ball thrust bearing including an opening, and the method comprises placing the post through the opening before the supporting step. 14. The method of claim 12, wherein the bag includes a cavity, and the method comprises placing the bearing in the cavity. 15. The method of claim 12, wherein the bearing includes a plurality of roller elements, and the supporting step comprises simultaneously contacting both the fluid-agitating element and the bag with the plurality of roller elements. 16. An apparatus intended for receiving and mixing a fluid, comprising: a fluid-agitating element; a collapsible bag capable of receiving the fluid and the fluid-agitating element; and a roller bearing for providing low-friction support for the fluid-agitating element. 17. An apparatus intended for receiving and mixing a fluid, comprising: a magnetic fluid-agitating element; a bag capable of receiving the fluid, said bag including a flexible wall carrying a rigid receiver for receiving the fluid-agitating element; and a bearing for providing low-friction support for the magnetic fluid-agitating element. 18. The apparatus of claim 17, wherein the bearing comprises a first race connected to the fluid-agitating element, a second race connected to the rigid receiver, and a plurality of rolling elements adapted for engaging the first and second races. 19. The apparatus of claim 17, wherein the bearing comprises a thrust bearing. 20. The apparatus of claim 17, wherein the rigid receiver includes a peripheral flange forming a support surface for the second race. 21. The apparatus of claim 20, wherein the peripheral flange of the rigid receiver is attached to the flexible wall of the bag. 22. The apparatus of claim 20, wherein the rigid receiver comprises a projection extending inwardly into an interior compartment of the vessel. 23. An apparatus intended for receiving and agitating a fluid, comprising: a flexible bag having an interior compartment adapted for receiving the fluid under sterile conditions; and a rotatable fluid-agitating element positioned in the interior compartment; wherein the bag includes a wall forming a cavity and a bearing adapted for promoting rotation of the fluid-agitating element. 24. The apparatus of claim 23, wherein the bearing comprises a roller bearing connected to the wall of the bag. 25. The apparatus of claim 23, wherein the cavity is at least partially bounded by a rigid wall that supports the fluid agitating element in the bag. 26. The apparatus of claim 23, further including a motive device for positioning in the cavity to cause rotation of the fluid-agitating element. 27. The apparatus of claim 23, wherein the bearing is positioned in the cavity. 28. An apparatus intended for receiving and mixing a fluid, comprising: a fluid-agitating element; a bag having an interior compartment capable of receiving the fluid and the fluid-agitating element under sterile conditions; a shaft projecting into the interior compartment for driving the fluid-agitating element; and at least one roller bearing associated with the shaft. 29. The apparatus of claim 28, further including a non-contact coupling for rotating the fluid-agitating element. 30. The apparatus of claim 29, wherein the shaft depends from an upper portion of the bag. 31. The apparatus of claim 30, wherein the non-contact coupling comprises a magnetic coupling. 32. The apparatus of claim 28, wherein the roller bearing comprises a ball bearing. 33. The apparatus of claim 28, further including a rigid receiver for supporting the shaft. 34. The apparatus of claim 28, wherein the shaft comprises a tubular structure.
