<p>An automatic device has a pipette (46) which is movable by motors along a guided path (48) between first and second locations at which a supply and storage vial (43) and a rack (45) for carrying one or more receptacle tubes (44) are respectively positioned. The motors operate also to lower the tip of the pipette (46) into positions to aspirate liquid from the storage vial (43) and to expel the aspirated liquid into one of the receptacle tubes (44), and the pipette has associated with it an automatically operating device for drawing liquid into and expelling liquid from the pipette tip. In an alternative construction, a single location is provided in which either a supply vial or a dispensing container can be positioned. In automatic operation, all of the liquid in the vial is drawn into the pipette and is subsequently discharged in required quantities into dispensing containers placed successively in said locations. In both constructions, all essential data concerning the contents of the vial are automatically read from the vial and stored and/or displayed. Similarly essential data relating to the contents discharged into the dispensing containers is stored and/or displayed.</p> |
