Abstract
This invention relates to a temperature control apparatus for generating and maintaining a differential temperature gradient across a block that may be used, for example, to conduct biological reactions. According to one embodiment of the present invention, a gradient block includes a top plate and a data storage device. The data storage device is adapted to be connected to a control unit and stores data related to the calibration of the gradient block. According to another embodiment of the present invention, an apparatus for generating a temperature gradient across a gradient block includes a gradient block and a control unit for controlling the temperature of the thermoelectric devices. The control unit includes a top plate, and at least four pairs of thermoelectric devices in thermal contact with the top plate, the pairs of thermoelectric devices being capable of independently transferring heat with the top plate and dividing the top plate into at least four heat transfer zones. The control unit contains a microprocessor capable of storing data.
