The invention relates to a sample sorting, conveying and receiving device for small microspheres. Said device is provided with a first module which contains at least one microsphere receiving zone (12). Said microsphere receiving zone (12) is provided with a plurality of microsphere receiving subzones (121) subject to the geometrical characteristics of a detachable sample receiving carrier (2) with respect to number, location and dimensions of individual sample chambers (21). Said microsphere receiving subzones are arranged in such a manner that their center lines (X-X) correspond to the center lines (Y-Y) of the individual sample chambers (21) of the sample receiving carrier (2) which chambers are to be filled or evacuated. Every microsphere receiving subzone (121) has a recess (122) for receiving a microsphere (3). Said recess has a depth (t) which is chosen such that once the microsphere (3)s received, it is substantially flush with a first surface (123) of the microsphere receiving zone (12). Every recess (122) has an opening (125) in its bottom area, which opening has a diameter that is smaller than the diameter of the microsphere (3). Said opening (125) is followed by a gap (126) which extends in the direction of the second surface (124) of the microsphere receiving zone (12). These gaps can be impinged upon by a negative pressure or overpressure via one or more channels or via an interlinked chamber of the first module.
