Abstract
The invention relates to a device for carrying out tests on and analyzing biological samples with temperature-controlled biological reactions. It comprises: A reaction chamber (5) for receiving a biochip (6). The reaction chamber comprises at least one transparent window (14) so that excitation light from outside can be radiated onto the biochip (6) and fluorescence light from the biochip can be radiated outward towards a measuring device. A membrane which forms at least one wall of the reaction chamber and is formed so as to be elastic so that the window and the biochip can be pressed against each other to displace the sample solution arranged thereinbetween. The device of the invention is distinguished in that the reaction chamber communicates with a compensation chamber. This permits creating predefined pressure conditions in the reaction chamber which, on the one hand, simplify the displacement of the sample solution and, on the other hand, prevent the formation of bubbles in the sample solution with high temperatures.
