Abstract:
A thermocycling device (10) and method of operating in which at least one first temperature sensor (1060) monitors a first temperature condition within the sample holder (64) and is adapted to provide a first electrical signal corresponding with the first temperature condition. In addition, at least one second temperature sensor (87) monitors a second temperature condition of a component external of the sample holder and is adapted to provide a second signal corresponding with the second temperature condition. At least one control device is adapted to interface with a power supply (1010) to control the delivery of power to a first thermal cycling element (60) and a second thermal cycling element (62), (both of which may sandwich a sample holder) and optionally an air mover (54); adapted to be in signaling communication with the first temperature sensor and the second temperature sensor; is configured for analysis of signals from the first temperature sensor and the second temperature sensor and; is configured such that, based upon such analysis, the at least one control device alters the power that is delivered to one or more of the first thermal cycling element and second thermal cycling element, and/or the air mover. The device Is controllably operated to account for thermal inertia effects.
