Abstract

A laboratory sample distribution system is presented. The system comprises a number of sample container carriers to carry one or more sample containers. Each sample container carrier comprises at least one magnetically active device. The system also comprises a transport plane to support the sample container carriers and a number of electro-magnetic actuators stationary arranged below the transport plane. The electro-magnetic actuators move the sample container carriers on top of the transport plane by applying a magnetic force to the sample container carriers. The system also comprises a rotating device comprising a rotating surface and a rotating drive to cause a rotational movement of the rotating surface. The system also comprises a control device to drive the electro-magnetic actuators, such that a sample container carrier to be rotated moves on the rotating surface, and to control the rotating drive such that a rotation of the sample container carrier is caused.

Claims

1. A laboratory sample distribution system, the laboratory sample distribution system comprising:

a number of sample container carriers adapted to carry one or more sample containers, each sample container carrier comprising at least one magnetically active device;

a transport plane adapted to support the sample container carriers;
