Abstract: The invention relates to a method and device for the automatic preparation of samples for analytical analysis in a sample tube, wherein the sample to be analyzed and the materials required for the preparation are added to the sample tube through dispensing devices, and the sample tubes and dispensing devices are displaced at least once in relation to each other before the complete addition of the sample and the materials. The device comprises an upper level that includes dispensing devices and a lower level that includes sample tubes. The lower level is displaced relative to the upper level to displace the sample tubes relative to the dispending devices.
