Abstract:
1. An apparatus for thermal cycling in an array of sample receptacles, said apparatus comprising: a hollow body having a single internal cavity with a working fluid therein that is partially vaporized, wherein said hollow body has a top surface with depressions therein that are spaced and shaped to receive a plurality of sample receptacles and thereby to place said depressions in direct and continuous contact with said undersides of said sample receptacles, said hollow body arranged to cause conductive heat transfer between walls of said cavity and walls of all of said sample receptacles, and wherein said internal cavity of said hollow body has a substantially flat floor and said depressions have undersides internal to said cavity that contact said flat floor; and one or more element that controllably heats said working fluid, cools said working fluid, or both, within said cavity to cause vaporization and condensation of said working fluid, wherein said element is below or at a side of the hollow body.
