Patent ID: 7841247

Claim:
A temperature controlled fluidic sample system comprising: a fluidic sample device comprising: a first substrate block having a first inner surface and a first outer surface; a second substrate block having a second inner surface and a second outer surface; a first groove formed in the first inner surface, the first groove having first and second ends opening to a peripheral edge of the first substrate block; the first and second inner surfaces of the first and second substrate blocks facing each other so as to form a first through channel between the first and second substrate, wherein: the first through channel has first and second ends opening to a peripheral edge of the fluidic sample device; the first through channel incorporates said first groove; the first through channel is located between two imaginary planes that are spaced apart by a height (h) of the first through channel, the two imaginary planes being parallel to one another and defining between them a first volume in which the first through channel resides; and at least one temperature sensor configured to measure a temperature within the first volume; a heater thermally coupled to said first outer surface; a heat sink thermally coupled to said second outer surface; and a temperature controller configured to receive temperature information from said temperature sensor and cause the heater to provide heat and the heat sink to provide cooling, such that: a temperature gradient is formed between the first outer surface and the second outer surface; and a desired temperature is maintained within said first volume.
