Abstract
The invention relates to a method for the operation of a laboratory centrifuge (1), wherein a rotor (2) rotates around a horizontal rotational axis (3). It should be avoided that during the start-up of the laboratory centrifuge (1) or the deceleration of the laboratory centrifuge (1) for small angular velocities and small centrifugal forces resulting therefrom due to the gravitational acceleration the product (6) is biased by resulting components of the acceleration in vertical direction which change their sense of direction. For this purpose the acceleration of the rotor (2) is chosen such that when arriving for the first time in a reversing angular position (twelve o'clock position) there is already a centrifugal acceleration being larger than the gravitational acceleration. The corresponding applies for the deceleration of the rotor after the centrifugation.
