Abstract: A laboratory centrifuge for producing suspensions, sediments and the like, and for carrying out washing and similar processes, in which a motor-driven vertical shaft is arranged in a housing, said shaft carrying a shaft head on which magazines or such are pivotably mounted for receiving sample containers. The shaft head can be driven in either of two opposing directions and has two brackets arranged symmetrically to the axis of rotation the outwards extending arms of said brackets carrying an axle on which the magazines are pivotably mounted with axial play. The width of the magazines is slighter than the distance between the two bracket arms, and a locking device is present between the bracket arms and the magazines, becoming effective when the magazine abuts the respective bracket arm.

Abstract: A universal centrifuge adapted to be operated at pre-selected speeds for pre-selected time periods over a wide range of speeds to perform many different functions normally performed by different centrifuges. A safety system is included which prevents operation at high speeds unless a rotation head designed for high speed operation is mounted on the unit.
