  • Patent number: 8147777
    Abstract: A sample tube holder for receiving and holding a sample tube having a cylindrical shape, a length symmetry axis and an outer diameter lying in a predetermined range. The sample tube holder comprises a solid body comprising at least one elongated chamber adapted for receiving a longitudinal portion of a sample tube, and an elastic element associated with and located outside of said chamber. When a sample tube is arranged in the chamber there is a gap between the sample tube and the side walls of the chamber, and the elastic element is in direct contact with at least three points of the outer surface of the sample tube, the elastic element thereby holds the sample tube and brings the length symmetry axis of the sample tube into coincidence with the length symmetry axis of the chamber.

  • Patent number: 8100266
    Abstract: A laboratory storage and retrieval system and a method to handle laboratory sample tubes are disclosed. The laboratory storage and retrieval system for storing sample tubes and retrieving stored sample tubes comprises a rack handler section (12) and a storage section (14), the rack handler section (12) comprising a transport system and a determination unit, wherein the transport system receives and transports incoming primary racks (PR) containing sample tubes (S) to the determination unit for determining at least one given parameter of the sample tubes (S) relating to predetermined sort criteria in order to have the transport system unload the sample tubes from the analysed primary rack (PR) and resort the unloaded sample tubes into appropriate storage racks (SR) depending on the determined sample tubes' sort criteria parameter for storage in the storage section (14) in the storage racks.

  • Publication number: 20070253284
    Abstract: A shaker device for shaking liquids in a clinical chemistry analyzer comprises an eccentric pin on a rotatable disk, a motor for rotating the disk and a movable piece having a joint for receiving the eccentric pin. The movable piece is mounted on a first movable part of a first linear motion guide having a first rail on which the first movable part can slide in a first direction (Y-direction). The first rail of the first linear motion guide is mounted on an intermediate plate which is mounted on a second movable part of a second linear motion guide having a second rail on which the second movable part can slide in a second direction (X-direction) which is normal to the first direction.
