Patent ID: 8400306

Claim:
A laboratory device comprising: a rack holding assembly, one or more laboratory racks for holding at least one laboratory vessel, the one or more laboratory racks having a generally rectangular shape with a RFID chip applied to one side surface in a position offset as to the center axis of the laboratory rack, such that the location of the RFID chip determines the orientation of the laboratory rack and the position of the at least one laboratory vessel, and an antenna structure element for wireless coupling with the RFID chip of the one or more laboratory rack, the antenna structure element comprising a substantially flat carrier substrate with a first carrier surface and a second carrier surface opposite the first carrier surface, and comprising at least two antennas applied on the carrier substrate, wherein a first antenna of the at least two antennas is applied on the first carrier surface and a second antenna of the at least two antennas is applied on the second carrier surface, the at least two antennas positioned in a staggered manner on alternating locations on the first and second carrier surfaces offset to each other by a distance corresponding to the position of the RFID chip of the laboratory rack, wherein coupling of the RFID chips attached to the laboratory racks is independent of the direction of insertion of the laboratory rack.
