Abstract:
1. A device for performing biological reactions in a nucleic acid sample, the device comprising: a reaction vessel receiving element comprising a plurality of reaction vessel holders, the plurality of reaction vessel holders comprising definable groups of reaction vessel holders; a plurality of Peltier elements, each Peltier element configured to heat and cool a group of reaction vessel holders; a gastight jacket containing a fluid changeable between a liquid state and a gaseous state, the gastight jacket being configured to provide temperature equalization among the reaction vessel holders; a cooling element having a first end facing toward the reaction vessel receiving element and a second end facing away from the reaction vessel receiving element; a heat conducting foil in contact with the reaction vessel receiving element, the heat conducting foil being disposed between the reaction vessel receiving element and each Peltier element, and further comprising heat conducting foil disposed between each Peltier element and the cooling element; and a controller configured to cycle the device through a predetermined time-temperature profile via heating and cooling.
