<p>A reaction apparatus 10 for receiving a plurality of reaction vessels 12 in which chemical and/or biochemical reactions occur comprises a thermal mount 14 having a plurality of wells 26 for receiving the vessels, a thermal module 16 having a first side thermally coupled to the thermal mount, a first heat sink 18 thermally coupled to a second side of the thermal module wherein the heat sink has a body and a plurality of thermally conductive fins 32 that extend outwards from the body of the first heat sink, and a printed circuit board 54 having electronic components for controlling the thermal module, an excitation light source 62, and a light sensor 52. A first set of light waveguides 60 is provided for delivering excitation light to a reaction vessel, and a second set of light waveguides 38 is provided for receiving light from a reaction vessel and for delivering the light to the light sensor. The first heat sink comprises an interior space 5 with the printed circuit board, in which the excitation light source, the light sensor and the light waveguides are arranged.</p> |
