A receptacle having a plurality of interconnected chambers arranged to permit multiple process steps or processes to be performed independently or simultaneously. The receptacles are manufactured to separate liquid from dried reagents and to maintain the stability of the dried reagents. An immiscible liquid, such as an oil, is included to control loading of process materials, facilitate mixing and reconstitution of dried reagents, limit evaporation, control heating of reaction materials, concentrate solid support materials to prevent clogging of fluid connections, provide minimum volumes for fluid transfers, and to prevent process materials from sticking to chamber surfaces. The receptacles can be adapted for use in systems having a processing instrument that includes an actuator system for selectively moving fluid substances between chambers and a detector. The actuator system can be arranged to concentrate an analyte present in a sample. The detector can be used to detect an optical signal emitted by the contents of the receptacle.

1. A closed receptacle having a plurality of interconnected chambers, the chambers including directly connected first and second chambers, wherein the first chamber has at least one chamber wall having a greater water vapor transmission rate than any chamber wall of the second chamber such that water vapor passes through the at least one chamber wall of the first chamber at a faster rate than it passes through any chamber wall of the second chamber, and wherein the first chamber contains a dried substance and the second chamber contains a liquid substance capable of altering the state or a characteristic of the dried substance. 2. The receptacle of claim 1, wherein the liquid substance is capable of reconstituting, dissolving or rehydrating the dried substance. 3. The receptacle of claim 2, wherein the dried substance is a lyophilized reagent. 4. The receptacle of claim 1, wherein the chamber wall of the first chamber comprises an optically transmissive region. 5. The receptacle of claim 4, wherein the second chamber does not comprise a chamber wall having an optically transmissive region. 6. The receptacle of claim 1, wherein multiple, liquid-holding chambers are directly connected to the first chamber, and wherein the first chamber has at least one chamber wall having a greater water vapor transmission rate than any chamber wall of the multiple, liquid-holding chambers directly connected thereto such that water vapor passes through the at least one chamber wall of the first chamber at a faster rate than it passes through any chamber wall of any of the multiple, liquid-holding chambers directly connected thereto. 7. The receptacle of claim 1, wherein multiple chambers are directly connected to the first chamber, and wherein the first chamber has at least one chamber wall having a greater water vapor transmission rate than any chamber wall of the multiple chambers directly connected thereto such that water vapor passes through the at least one chamber wall of the first chamber at a faster rate than it passes through any chamber wall of any of the multiple chambers directly connected thereto. 8. The receptacle of claim 1, wherein the first and second chambers are directly connected to each other by a blocked connection. 9. The receptacle of claim 8, wherein the connection is an openable connection that can be altered from a closed state to an open state when a substance-moving force is applied to the contents of the second chamber. 10. The receptacle of claim 9, wherein the substance-moving force is one or more compressive forces applied to a flexible portion of the second chamber. 11. The receptacle of claim 10, wherein the chamber wall of the first chamber is flexible, and wherein the flexible portion of the second chamber is a chamber wall. 12. The receptacle of claim 11, wherein the receptacle comprises opposed members configured to define the plurality of interconnected chambers. 13. The receptacle of claim 12, wherein at least one of the opposed members comprises a flexible sheet, the flexible sheet comprising the flexible walls of the first and second chambers, and wherein the flexible walls of the first and second chambers facilitate substance movement between the first and second chambers. 14. The receptacle of claim 13, wherein each of the opposed members comprises a flexible sheet. 15. The receptacle of claim 14, wherein each of the flexible sheets comprises a plurality of plastic layers. 16. The receptacle of claim 15, wherein each of the flexible sheets comprises a foil layer. 17. The receptacle of claim 16, wherein the foil layers fully cover the second chamber, and wherein the foil layers less than fully cover the first chamber. 18. The receptacle of claim 12, wherein the first and second chambers are directly connected to each other by an openable connection that can be altered from a closed state to an open state when a substance-moving force is applied to the contents of the second chamber. 19. The receptacle of claim 18, wherein the substance-moving force is one or more compressive forces applied to the flexible wall of the second chamber. 20. The receptacle of claim 19, wherein the plurality of interconnected chambers are defined by seals formed between the opposed members. 21. The receptacle of claim 20, wherein the first and second chambers are adjacent each other, and wherein the openable connection is an opening blocked by a burstable seal that is altered from the closed state to the open state when the substance-moving force is applied to the flexible portion of the second chamber. 22. The receptacle of claim 21, wherein the burstable seal is a heat seal. 23. The receptacle of claim 1, wherein the receptacle is contained within a sealed, desiccant-holding container. 24. The receptacle of claim 1, wherein each of the plurality of interconnected chambers is positioned adjacent to at least one other chamber of the receptacle.
