Abstract:
A reaction assembly for selectively heating or cooling a reaction vessel, said reaction assembly including:a heat conductive reaction block having at least one exterior wall and a reaction vessel receiving cavity formed in said block inwardly of said exterior wall,a thermoelectric module mounted in heat transfer engagement with said exterior wall of said heat conductive reaction block,a fluid heat exchange element mounted in heat transfer engagement with said thermoelectric module,said thermoelectric module being alternately energizable to selectively remove heat from said exterior wall of said heat conductive reaction block and transfer said heat to said fluid exchange element or to supply heat to said exterior wall of said heat conductive block,said reaction vessel shaped to be received in said reaction vessel receiving cavity and being elongated with upper and lower portions,said reaction vessel receiving cavity being sized to receive only said lower portion of said reaction vessel with said upper portion of said reaction vessel extending above said reaction block,an auxiliary fluid heat exchange element having a reaction vessel receiving passage extending therethrough in alignment with said reaction vessel receiving cavity and positioned to receive an upper portion of said reaction vessel, andsaid auxiliary fluid heat exchange element having fluid passages formed therein for attachment to a fluid supply.
