A plurality of reagent dispensing tips (15) are inserted through frustoconical openings (28) in a cover (16) of a cleaning chamber in the form of intersecting axial bores (14) and sprayed with wash fluid from spray passages (34) in the peripheral wall (20) of the cover (16). Wash fluid from the spray passages (34) and flowing through the reagent dispensing tips (15), if hollow, can be drained from the cleaning chamber through a drain port (42). Air is drawn through the frustoconical openings (28) around the reagent dispensing tips (15) into the cleaning chamber, through filter element (64) and from a waste chamber (50) by a vacuum source (78) to remove wash fluid from and otherwise dry the reagent dispensing tips (15).
