ABSTRACT:
An apparatus for thermally controlling and optically interrogating a reaction mixture includes a vessel [2] having a chamber [10] for holding the mixture. The apparatus also includes a heat-exchanging module [37] having a pair of opposing thermal plates [34A,34B] for receiving the vessel [2] between them and for heating/and or cooling the mixture contained in the vessel. The module [37] also includes optical excitation and detection assemblies [46,48] positioned to optically interrogate the mixture. The excitation assembly [46] includes multiple light sources [100] and a set of filters for sequentially illuminating labeled analytes in the mixture with excitation beams in multiple excitation wavelength ranges. The detection assembly [48] includes multiple detectors [102] and a second set of filters for detecting light emitted from the chamber [10] in multiple emission wavelength ranges. The optics assemblies [46,48] thus provide a multi-channel system for detecting a plurality of different target analytes in the mixture.
