Apparatus and method for providing visual signals relating to a plurality of laboratory sample carriers

Abstract

There is an apparatus () and a method for providing visual signals relating to a plurality of laboratory sample carriers (). Laboratory sample carriers () are placed on corresponding carrier bays () of a tray () wherein each sample carrier () displays an identification code (). A digital image of at least part of the tray () is taken with a digital camera (). The digital image is processed with a processing device () to read the laboratory sample carrier identification codes () in the image. A visual signal emitting device () is activated to emit at least one visual signal for each occupied carrier bay () included in the image wherein the visual signal emitted for each carrier bay () is determined by the sample carrier identification code () read by the processing device () from a corresponding carrier bay part of the processed image.
