| 1. A thermocycler for processing biological or chemical samples, comprising:
a block comprising physically discrete segments, the segmented block configured to receive a plurality of sample volumes in
a standard microtiter plate;
a thermoelectric device comprising a plurality of thermoelectric elements, each thermoelectric element in dedicated thermal
communication with only one segment of the block such that each segment is aligned with a thermoelectric device; and
a plurality of temperature equalization plates, each temperature equalization plate being dedicated to provide a substantially
uniform temperature to only one segment of the block during thermal cycling such that each segment is aligned with a respective
temperature equalization plate, and each temperature equalization plate being configured to circulate a cooling medium therein.
