Abstract
An arrangement for balancing a centrifuge rotor during operation comprises means (5, 8) forming an annular channel (11) which concentrically surrounds the rotational axis of the rotor and in which there are arranged three separately movable balancing bodies (12). The annular channel (11) is partly defined by a slide (8) movable axially by control means (9, 14-17) to and from contact with the balancing bodies (12) for arresting and releasing them in the channel during the rotor operation.
