1. A method comprising:
- providing a first and a second fluid maintained separately from each other by a third fluid in a common, sealed vessel, wherein the third fluid is adjacent to and substantially immiscible with the first and second fluids, and wherein the first, second and third fluids are stored within the common, sealed vessel for at least one day;
unsealing the vessel;
transferring the first, third, and second fluids in series from the vessel to a reaction site to carry out a predetermined chemical or biochemical reaction; and
avoiding substantial contact between the first and second fluids, at least until after the fluids have been applied to the reaction site.

Abstract
Method and device for storing and/or delivering fluids, wherein at least a first and a second fluid, such as chemical or biochemical reagents or rinse solutions, are maintained separately from each other in a common vessel and transferred in series from the vessel to a reaction site to carry out a predetermined chemical or biochemical reaction. Separation may be achieved by interposing a third fluid, e.g., a gaseous fluid plug, between the first and second fluids.

24. A method comprising:
-
providing a reaction site; providing a first and a second fluid statically maintained separately from each other by a third fluid adjacent to and substantially immiscible with the first and second fluids in a common, sealed vessel for greater than one minute, wherein the vessel and the reaction site are formed in a microfluidic chip; unsealing the vessel; applying in series the first, third, and second fluids to the reaction site; and avoiding substantial contact between the first and second fluids, at least until after the fluids have been applied to the reaction site. - View Dependent Claims (25, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)

31. A method comprising:
-
providing a reaction site; providing a first and a second fluid statically maintained separately from each other by a third fluid adjacent to and substantially immiscible with the first and second fluids in a common, sealed vessel for greater than one minute, wherein the vessel and the reaction site are integrally connected to one another; unsealing the vessel; applying in series the first, third, and second fluids to the reaction site; and avoiding substantial contact between the first and second fluids, at least until after the fluids have been applied to the reaction site. - View Dependent Claims (43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54)
