Abstract
A tube rotator for rotating test tubes arranged in a tube rack as well as a system and process for reading information of machine-readable labels of the test tubes are disclosed. The tube rotator may comprise a pivoted lever having two lever arms, a friction wheel rotatably fixed to one lever arm and arranged to be brought in or out of contact with at least one test tube for rotating the test tube by friction. A first actuator may be rotatably coupled to the friction wheel, and a pretensioner which is capable of generating a pretensioning force may act on the lever for pivoting the lever in one pivoting direction. An eccentric may be rotatably fixed with respect to the base and arranged to roll off the other lever arm for pivoting the lever in another pivoting direction. A second actuator may be rotatably coupled to the eccentric.
