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.

Laboratory apparatus for simultaneously carrying out reactions in a plurality of samples

An apparatus for photometrically testing several specimens each irradiated by a light source, the light altered by the specimens being detected by an optical device and analyzed, the apparatus including a light source, a plurality of sample holders configured adjacent to one another on a support, a detector that receives altered light from sample within the sample holders, the detector including a filter for eliminating interfering light, a sensor having a sensor face and a diffusing optical member located between the filter and the sensor, wherein light is diffused and shines on a greater portion of the sensor surface, and with a more homogeneous brightness as compared to when the light is not diffused.
