The efficient temperation of a sample is achieved when the sample is subject ed to centrifugation simultaneously with heating and optionally also cooling. This is achieved in a device comprising at least a rotor (1) for holding reaction vessels (2), a motor (3), connected to said rotor, means such as a processor (4) for controlling the speed of the rotor, and means (5 and 6) fo r heating and cooling the contents of the reaction vessels, wherein the means (6) for heating cover the apices of the reaction vessels for at least part o f the rotational path of said vessels and that the means for heating operate a t a temperature significantly higher than the melting temperature of the reaction vessels. The invention further relates to a method for performing chemical reactions and in particular a method for performing biochemical reactions involving thermocycling, for example PCR-reactions. |
