ABSTRACT:
An apparatus for cutting up biological sample material, including a sample container, a rotary drive device separate from the sample container, and a shaft rotatably arranged in the sample container, wherein the shaft has a laterally projecting cutting device in the region of a working end and has a coupling piece in the region of a coupling end, said coupling piece being accessible from outside and being designed for coupling engagement with a coupling counterpart of the rotary drive device, wherein the shaft (14) is arranged with lateral guidance and in an axially displaceable manner in the sample container (10), the coupling piece (19) and the coupling counterpart (21) are designed for producing coupling engagement which is positive-locking in the direction of rotation (23) and permits an axial displacement, and the cutting device (16) is designed in a propeller shape in such a way that, during rotation of the shaft (14) in the working direction, it exerts a propulsive force on the latter in the direction of the coupling end (18).
