1. A device for handling a sample container having an open side, the device comprising:
a head having an inner chamber with an opening arranged at one end, the inner chamber having a constant cross-sectional shape taken perpendicularly to a longitudinal axis of the inner chamber, wherein the opening extends perpendicularly to the longitudinal axis;
a rotor part arranged within the inner chamber;
a rotor drive arranged for rotating the rotor part around the longitudinal axis;
a rotor displacer arranged to displace the rotor part along the longitudinal axis;
a piston comprising an edge part of a cross-sectional shape corresponding to the cross-sectional shape of the inner chamber; and
a piston displacer arranged to displace the piston along the longitudinal axis so that the edge part of the piston will scrape a wall of the inner chamber;
the device further comprising:
a holder arranged for supporting a sample container so that an open side of the sample container is in tight connection with the opening of the inner chamber; and
a head drive arranged for alternating an orientation of the head between a position where the opening of the inner chamber is oriented upwards and a position where the opening of the inner chamber is oriented downwards.
