ABSTRACT:
A system for controlling the temperature of fluidic samples includes a device having a first outer surface and a second outer surface which are parallel to one another. The interior of the device contains two or more channels suitable for accommodating samples. The channels lay on a common plane that is also parallel to the first and second outer surfaces. A temperature sensor is positioned between the channels along the common plane. A heater is thermally coupled to one of the two outer surfaces while a heat sink is coupled to the other of the two outer surfaces, thereby establishing a temperature gradient between the first and second outer surfaces. A temperature controller receives sensed temperature input from the temperature sensor and adjusts the heater in response thereto.
