Abstract:
1. Apparatus for controlling temperature in a plurality of samples, said apparatus comprising: a multi-receptacle sample block, a thermoelectric module, and a heat sink block, all shaped to be capable of arrangement in a stacked configuration in which said sample block is in thermal contact with said thermoelectric module and said thermoelectric module is in thermal contact with said heat sink block, a support frame sized to receive said sample block, said thermoelectric module, and said heat sink block in said stacked configuration, a first loop-shaped gasket sized to encircle said sample block along a peripheral surface thereof and thereby form a seal between said sample block and said support frame, and a second loop-shaped gasket sized to encircle said heat sink block along a peripheral surface thereof and thereby form a seal between said heat sink block and said support frame, said sample block, said heat sink block, said support frame, and said loop-shaped gaskets thereby together forming a sealed enclosure surrounding said thermoelectric module and protecting said thermoelectric module from atmospheric moisture.
