Abstract: The invention relates to a heated reaction chamber for processing a biochip and to a method for controlling said reaction chamber. The heated reaction chamber for processing a biochip comprises a chamber wall, constituted by a flexible circuit board (10), a circuit path (10.3) being configured on the flexible circuit board (10) and being used as the heating device. The use of a flexible circuit board as the wall of a reaction chamber allows for a low thermal capacity of the reaction chamber in the area of the heating device, thereby allowing the chamber to be heated up quickly.

Abstract: The cartridge according to the invention for analysing biological samples comprises: a reaction chamber and a biochip mounted in the reaction chamber, a filling nozzle connected so as to communicate with the reaction chamber, and a compensation chamber connected so as to communicate with the reaction chamber, wherein the reaction chamber, the compensation chamber and all lines connected thereto form a chamber sealed as far as the filling nozzle, wherein the filling nozzle forms a free passage to the reaction chamber from outside the cartridge, and a stopper is provided which fits positively and tightly in the filling nozzle in such a way that, when pressed in over a certain distance, fluid is displaced from the filling nozzle towards the reaction chamber.

Abstract: The invention relates to a cooling device for a reaction chamber for processing a biochip and to a method for controlling said cooling device. The cooling device (50) according to the invention comprises a cooling piston (51), a cooling unit (52) for cooling the cooling piston (51) and a drive (53) for displacing the cooling piston (51) or the reaction chamber in such a manner that the cooling piston can be brought into contact with a wall of the reaction chamber (5) and can be removed again. The cooling device (50) according to the invention allows high cooling rates and a high reproducibility of cooling processes. It has a simple design and can be reliably used in portable devices for examining biochips.
