Abstract: A method of filling a cartridge that includes a reaction chamber, a biochip mounted in the reaction chamber and a compensation chamber connected so as to communicate with the reaction chamber. The method includes placing a filling nozzle, which is connected so as to communicate with the reaction chamber, such that it is facing upwards, filling a liquid biological sample into the filling nozzle, pressing a stopper into the filling nozzle in order to force sample liquid into the reaction chamber, so that the reaction chamber is filled from bottom to top and an air bubble remains in the compensation chamber downstream of the reaction chamber.

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: A device for photometric measurement of several samples (12) that are exposed to radiation from a light source (14) associated therewith. The light modified by the samples (12) is intercepted by an optical device (19) and is guided as a sum of all the light radiated from all samples (12) to at least one sensor (27) for measuring the intensity and evaluation thereof in an evaluation device (32) arranged downstream. The light sources (14) are controlled individually by a control device (31) and the evaluation device (32) and the control device (31) are controlled such that the evaluation device (32) separates the light from each sample (12) from the light of the other samples. The control device (31) modulates the light source (14) with various signals, which are pre-assigned to the evaluation device (32) and used to determine the light signals of the individual samples (12) from the sum signal received by the sensor (27).
