The tank of claim 11, further comprising a moveable mixing element disposed within the tank. 17. A material processing bag having an outer wall comprising a polymeric film material, wherein said bag further comprising the drain connector of claim 1 sealingly engaged thereto. 18. The bag of claim 17 wherein the bag and the drain connector are sterilized. 19. The bag of claim 17 wherein said polymeric film is a substantially optically transmissive. 20. The bag of claim 17, further comprising a moveable mixing element disposed within the bag. 21. The drain connector of claim 1 wherein the drain flange comprises a substantially optically transmissive material. 22. The drain connector of claim 1, further comprising a sensor affixed to any of the plunger, the drain flange, and an outlet tube associated with any of the plunger and the drain flange, wherein the sensor is adapted to monitor at least one characteristic of a substance contained or flowing within the drain connector. 23. A method for fabricating a sterile processing receptacle, the method comprising the steps of: providing a hollow container; providing a selectively closeable drain connector comprising: a hollow plunger including a plunger body having a first closed end, a second open end, a wall with an exterior surface and with an interior surface bounding a hollow core, a first and a second circumferential sealing element disposed along the exterior surface, and a travel stop, the plunger body further defining at least one passage extending from the exterior surface into the hollow core and disposed between the first and the second circumferential sealing element; and a drain flange defining an aperture adapted to receive the plunger, the aperture being bounded by an inner surface adapted to sealingly engage the first and the second circumferential sealing element when the drain connector is in an open state, and to sealingly engage the second circumferential sealing element when the drain connector is in a closed state; wherein any of the plunger and the flange is adapted to move relative to the other; and wherein the drain connector is characterized by any one or more of the following: (i) the drain flange has a radially extending flange lip adapted for placement against a bottom wall of said tank or bag, and the first sealed end of the plunger is disposed substantially flush against an upper surface of said radially extending flange lip when said drain connector is in a closed state; and (ii) a portion of the plunger is arranged to travel into an interior volume of said tank or bag when said drain connector is in an open state; and joining the drain connector to the hollow container to form a fluid processing receptacle; and sterilizing the fluid processing receptacle. 24.
