  • Patent number: 9945882
    Abstract: ABSTRACT The present invention lies in the field of automated analysis apparatuses and relates to a method for transferring a liquid volume from a first liquid vessel into a second liquid vessel. The method ensures increased pipetting accuracy, even from liquid vessels which have foam on the surface of the liquid.

  • Patent number: 9804180
    Abstract: An incubation device for an automatic analysis apparatus includes an incubation unit having a number of reception positions for reaction vessels, a first transfer arm having a gripping device for one or more reaction vessels, which is configured to move the gripping device into a first access region, a second transfer arm having a gripping device for one or more reaction vessels, which is configured to move the gripping device into a second access position. This allows a larger sample throughput of the automatic analysis apparatus with, at the same time, frictionless and reliable operation. To this end, the first and the second access regions do not overlap, and the incubation unit is mounted so that it can be moved in such a way that at least one of the reception positions reaches the first and the second access regions.

  • Publication number: 20120072027
    Abstract: A sample analyzer with fixed and variable indexing that is structured and arranged to align reaction vessels, e.g., cuvettes, at a pre-determined, fixed point while maintaining a positional sequence using variable indexing. Variable indexing allows cuvettes to be presented to multiple, fixed point resources at multiple occasions in a systematic progression in a highly efficient manner. The presentation of cuvettes to multiple, fixed point resources at multiple times is superior to existing indexing.
