Abstract: The invention relates to a reaction chamber system (10, 70) for processing samples, comprising a reaction chamber (12), a sample carrier (26) arranged at least in the reaction chamber (12). When in operation, said sample carrier can be displaced in relation to the reaction chamber (12) by means of a drive device (30) which is coupled to the sample carrier (26). The reaction chamber system also comprises heating means (50) for warming the samples. The invention is characterized in that the heating means (50, 54) are arranged on the sample carrier (26) and can be displaced with the sample carrier (26) when in operation.
