Temperature control block module designed for an apparatus for the thermal treatment of samples, comprising: a temperature control block, at least one temperature control element, a heat sink and an ejection mechanism that serves to lift from the temperature control block reaction vessels that have been placed on the temperature control block, wherein the ejection mechanism comprises at least a first ejection tappet and a second ejection tappet, wherein the first and the second ejection tappet are mounted in the temperature control block module in such a way that they are perpendicular to a plane in which the temperature control block is arranged and can be moved from a first position, in which they are retracted into the temperature control block module, to a second position in which they are extended out of the temperature control block module, wherein the temperature control block module further comprises a first tappet drive which has an operative connection to the first ejection tappet to drive the movement of the first ejection tappet from the first to the second position or from the second to the first position, and wherein the temperature control block module comprises a second tappet drive, which is different to the first tappet drive and which has an operative connection to the second ejection tappet to drive the movement of the second ejection tappet from the first to the second position or from the second to the first position, and wherein the movements of the first and the second ejection tappet can be driven and controlled independently of one another with a different force, a different speed and/or at different times. a temperature control block, at least one temperature control element, a heat sink and an ejection mechanism that serves to lift from the temperature control block reaction vessels that have been placed on the temperature control block, wherein the ejection mechanism comprises at least a first ejection tappet and a second ejection tappet, wherein the first and the second ejection tappet are mounted in the temperature control block module in such a way that they are perpendicular to a plane in which the temperature control block is arranged and can be moved from a first position, in which they are retracted into the temperature control block module, to a second position in which they are extended out of the temperature control block module, wherein the temperature control block module further comprises a first tappet drive which has an operative connection to the first ejection tappet to drive the movement of the first ejection tappet from the first to the second position or from the second to the first position, and wherein the temperature control block module comprises a second tappet drive, which is different to the first tappet drive and which has an operative connection to the second ejection tappet to drive the movement of the second ejection tappet from the first to the second position or from the second to the first position, and wherein the movements of the first and the second ejection tappet can be driven and controlled independently of one another with a different force, a different speed and/or at different times.
