Abstract

The invention relates to a laboratory apparatus for simultaneously carrying out reactions in a plurality of samples which are arranged in an array. The apparatus includes an illumination device, which emits illumination light onto the samples, a detection device, which generates a signal dependent on the light intensity of the light coming from the samples and which forwards the signal to an evaluation device, and a monitoring device for checking the functioning of the illumination device. The illumination device has a plurality of light-emitting diodes assigned in each case to one of the samples, and the monitoring device has electrical devices which can be used to perform an electrical functional check of the light-emitting diodes. The monitoring device is adapted to generate a signal when a functional disturbance of a light-emitting diode is ascertained.
