Definitions

  • the invention concerns a sample tube rack 11 for holding a plurality of sample tubes 12, 13, the tubes having outer diameters which lie within a predetermined diameter range.
  • the invention also concerns a sample tube rack assembly for holding and positioning a plurality of sample tubes, the tubes having outer diameters which lie within a predetermined diameter range.
  • the invention further concerns an analyzer for performing medical diagnostic analysis of biological samples, the analyzer including a sample tube rack assembly for holding and positioning a plurality of sample tubes, the tubes having outer diameters which lie within a predetermined diameter range.
  • Analyzer systems for performing medical diagnostic analysis of biological samples use sample tubes for receiving the samples to be analyzed.
  • Sample tubes of different sizes are commercially available. There are sample tubes with an outer diameter which lies within a predetermined range, e.g. between 11.5 and 16.5 millimeter.
  • sample tube racks which have a plurality of receptacles for holding and positioning tubes.
  • each rack receptacle corresponds closely to the specific outer diameter of a sample tube of a particular size.
  • the disadvantage of this first type of rack is that a large number of rack types are needed for holding the sample tubes to be processed in the analyzer system, because the sample tubes received by the system have a plurality of different outer diameters.
  • each rack receptacle is slightly larger than the largest outer diameter of a sample tube to be processed in the analyzer system.
  • Adapter members inserted in the rack receptacles are used for receiving therein sample tubes which have smaller outer diameters.
  • the disadvantage of this solution is on the one hand that adapter members with different inner diameters are required which correspond to the various outer diameters of the sample tubes received by the system, and on the other hand there is the risk of mistakes when selecting the adapter member for a specific sample tube, i.e. an adapter of the wrong size may be inserted by mistake in a receptacle of a rack.
  • each rack receptacle is slightly larger than the largest outer diameter of a sample tube to be processed in the analyzer system and a leaf spring or a flexible tongue attached to the side wall of each receptacle makes it possible that sample tubes having different outer diameters which lie within a certain range can be held and positioned in each rack receptacle.
  • the disadvantages of this third type of rack are that it is on the one hand more expensive, and on the other hand less reliable in holding a sample tube in the desired position due to the flexibility and possible failure of the integrated leaf springs or tongues used.
