Zusammenfassung:PROBLEM TO BE SOLVED: To provide an apparatus and method for rapid thermal cycling including a thermal diffusivity plate.SOLUTION: A thermal diffusivity plate can provide substantial temperature uniformity throughout the thermal block assembly during thermal cycling by a thermoelectric module. An edge heater can provide substantial temperature uniformity throughout the thermal block assembly during thermal cycling. Specifically an apparatus for thermally cycling biological samples comprises the followings: a thermal block assembly for receiving the biological samples; a thermoelectric module coupled to the thermal block assembly; and a heat sink, wherein the heat sink is coupled to the thermoelectric module, the heat sink comprises a base plate, fins, and a thermal diffusivity plate, and the thermal diffusivity plate comprises a different material than the base plate and fins. In the heat sink, the thermal diffusivity plate provides substantial temperature uniformity to the thermal block assembly during thermal cycling.
