Apparatus for the rapid vibration of sample container tubes, e.g. containing biological samples, comprising a support plate (22) for the sample tubes and concentric bearings (28,30) for the plate mounting in a centering crown (26), which is on an elastic suspension (29) at the frame (10), where each bearing has two roller bearings within each other, is new. Apparatus for the rapid vibration of sample container tubes, e.g. containing biological samples, comprises a support plate (22) for the sample tubes and concentric bearings (28,30) for the plate mounting in a centering crown (26), which is on an elastic suspension (29) at the frame (10), where each bearing has two roller bearings, within each other and a third eccentric ball bearing (18) is at the mouthpiece of the drive shaft (20) from the electromotor (12), which has an axial movement within its bearing.
