The invention relates to a system (1) for locating or tracking objects (2) which can be positioned on the work table (3) of a laboratory device (4). The system (1) comprises at least: a) one central transmitter (5) which can transmit and receive radiofrequency (RF) signals, convert received RF signals and transmit the converted signals to a computer (7); b) a local unit (6) which is mounted on a surface (8) of the work table (3) and which can receive and transmit RF signals; c) radio frequency ID (RFID) tags (10) which can be fixed to the local unit (6) and to laboratory articles (15) that are to be identified and/or located or tracked; d) a work table (3) of a laboratory device (4) and a computer (7) which can be joined to the laboratory device (4) and which is connected to the central transmitter (5) by means of an interface, wherein the computer (7) can communicate with the central transmitter (5), process signals received therefrom and respond to RFID tags (10) via the central transmitter (5). The inventive system (1) can be integrated into superordinate logical systems for the treatment and analysis of any particular kind of samples.
