Abstract: A thermocycling device includes a sample holder, a thermal reference and a heating and cooling device which is arranged between the sample holder and thermal reference. The heating and cooling device is in thermally conductive contact with the sample holder and with the thermal reference. The thermocycling device further includes a reference heating and cooling device for maintaining the temperature of the thermal reference at a predetermined temperature level during cycling, and a heat sink which is in thermally conductive contact with the reference heating and/or cooling device.

Abstract: The present invention is related to a thermocycling device (10), comprising at least one sample holder (11), at least one thermal reference (12) and at least one heating and/or cooling device (13), which is arranged between said sample holder(s) and said thermal reference. Said heating and/or cooling device is in thermally conductive contact with said sample holder(s) and with the thermal reference. Furthermore, the device comprises at least one reference heating and/or cooling device (14) for maintaining the temperature of the thermal reference at a predetermined temperature level during cycling and a heat sink (15) which is in thermally conductive contact with said reference heating and/or cooling device (14).
