Method for operating a laboratory centrifuge for centrifugalising a product, the laboratory centrifuge comprising a rotor which rotates about a horizontal rotational axis and at which the product is held at a distance from the rotational axis, a) the rotor being accelerated from a resting angular position of the product wherein the product is arranged between a 3:00 o'clock position and a 9:00 o'clock position and the product has an angular velocity of zero in such a way that for the first arrival in a reversing angular position of the rotor wherein the product is arranged in a 12:00 o'clock position the rotor has reached an angular velocity which is so great that the centrifugal acceleration acting upon the product is higher than the gravitational acceleration, and/or b) the rotor being decelerated from a reversing angular position of the product wherein the product is arranged in a 12:00 o'clock position and the product comprises an angular velocity which is so great that the centrifugal acceleration acting upon the product is higher than the gravitational acceleration to the first arrival at a resting angular velocity of the rotor wherein the product is arranged between a 3:00 o'clock position and a 9:00 o'clock position to an angular velocity of zero, characterised in that c) during the acceleration and/or deceleration of the product a 6:00 o'clock position is passed and the acceleration from the resting angular position to the first arrival at the reversing angular position and/or the deceleration from the reversing angular position to the first arrival at the resting angular positon is provided over an angular region between 180° and 270°, d) the loading and unloading of the product to the rotor and from the rotor is provided in a loading and unloading position which corresponds to the 6:00 o'clock position and da) subsequent to a loading at first by the drive of the rotor with a rotation in a first sense of the rotational direction is transferred into the resting angular position from which then the acceleration is provided with an opposite second sense of the rotational direction towards the reversing angular position and/or db) during the deceleration a rotation of the rotor is provided with a first sense of the rotational direction up to the resting angular position with subsequent reversing rotation with an opposite second sense of the rotational direction from the resting angular position into the unloading position. a) the rotor being accelerated from a resting angular position of the product wherein the product is
