Abstract

A unit (10) for the preparation of cells contained in a liquid comprises a storage chamber (20) configured to store the liquid containing the cells and to release the stored liquid via an exit opening (22) upon the application of a predetermined external force in particular a centrifugal force. A passage (30) adjacently arranged to the exit opening (22) has a cross section larger than that of the exit opening (22). The wall at the transition from the exit opening (22) to the passage (30) forms an edge (32). The unit further comprises an observation member (50) for receiving the released liquid and an absorbing means (40) arranged adjacent to the observation member (50) between the passage (30) and the observation member (50). The absorbing means (40) has an aperture (42) allowing the released liquid to travel onto the observation member (50) and removes the liquid so as to leave the cells on the observation member (50) for observation.
