Abstract
A self-balancing apparatus for a centrifuge is disclosed which employs two arcuately movable counterweights. The centrifuge has a plurality of receptacles for receiving one or more assay cartridges. Control apparatus in the centrifuge determines the location and number of received cartridges. Desired counterweight positions are then calculated which will substantially balance the centrifuge. The counterweights are moved into these positions prior to the centrifuge being operated at high speeds.
