Abstract:
1. A temperature control assembly for a multi-receptacle sample block, said assembly comprising: (a) thermoelectric means spanning a substantially flat area bounded by a perimeter; and (b) heat sink means comprising: (i) heat-dissipating fins positioned at an underside of said thermoelectric means and extending throughout and optionally beyond said flat area, and (ii) a slab of heat-conductive material positioned between, and in contact with, said underside of said thermoelectric means and said heat-dissipating fins, to transmit heat between said thermoelectric means and said heat-dissipating fins by conduction, said slab containing voids distributed across said slab within said perimeter of said flat area with a higher void density in regions surrounding a central region of said slab.
