Patent ID: 8101897

Claim:
A laboratory apparatus for simultaneously carrying out reactions in a plurality of samples which are arranged in an array, comprising: an illumination device having a plurality of light-emitting diodes, each of which is assigned to and emits illumination light onto one of the plurality of samples, a detection device, which generates signals dependent on the intensity of light coming from the samples, a monitoring device for checking the function of the illumination device, wherein the monitoring device includes electrical devices that perform an electrical, non-optical, functional check of the light-emitting diodes, and wherein the monitoring device generates a signal when a functional disturbance of one of the plurality of light-emitting diodes is ascertained, and an evaluation device that receives signals from the detection device and the monitoring device, wherein the evaluation device selectively discards a signal from the detection device for an assigned light-emitting diode whose function has been ascertained as being disturbed.
