Abstract
Abstract The invention presents a system for automatically identifying labware and sample containers. Labeled sample containers are inserted into the reception slots of a labeled labware. A sample condition label is affixed below each reception slot. The sample condition label is covered by the sample container when the sample container is inserted into the reception slot. An exposed sample condition label indicates the absence of a sample container in that reception slot. The labware containing the sample containers is installed on a labware holder having a labware condition label affixed to its surface. The labware condition label is covered by the labware when the labware is installed on the labware holder. An exposed labware condition label indicates the absence of a labware on the labware holder. The label information is read by an optical reader attached to a motorized track. Both the optical reader and the motorized track are connected to a data processor. The data processor stores the label information and controls the position of the optical reader.
