  • Patent number: 8361387
    Abstract: A method and system for automatically processing of liquid samples involving mixing of the samples with fluids are disclosed. The system includes a storing and handling device for storing and handling of fluid containers, which includes: a storing member provided with a plurality of storing positions, adapted for accommodating the fluid containers, the storing member having at least two storing levels, each of which extending in a plane, which are being stacked in a direction orthogonally aligned to the plane; and a handler, adapted for automatically transferring the fluid containers at least with respect to the storing positions. A method for operating such storing and handling device is also disclosed, wherein individual fluid containers are transferred between storing positions of a same or different storing levels in accordance with processing of the liquid samples.
