- - die Befestigungseinrichtungen (12, 14) zum reversiblen Fixieren von Spritzen flansch (21) und Spritzenkolben (25) in ihren Aufnahmen (3, 9) aufweist, von denen eine den Spritzenflansch (21) hintergreift,
- - die Kolbenstelleinrichtungen zum Verschieben des Aufnahmekörpers (8) im Pipettengehäuse (2) aufweist,
- - die eine ringförmige Abtasteinrichtung (6) mit über den Umfang verteilten Sen soren (7) für eine Information über eine Spritze und/oder deren Zustand auf einem Informationsträger in Form eines am Spritzenflansch angeordneten ringförmigen Kranzes mit mehreren axial gerichteten Abtastflächen mit einer axialen Position aufweist
- - und die eine Auswerteeinrichtung für eine von der Abtasteinrichtung (6) gelesene Information aufweist,
- - daß die Spritze (19) keine Abtastflächen aufweist, so daß die Sensoren (7) der Abtasteinrichtung (6) nicht betätigt werden, wenn die Spritze (19) mit Spritzen flansch (21) und Spritzenkolben (25) in den Befestigungspositionen angeordnet ist,
- - und sich die Spritze (19) außerhalb der Sensoren (7) an der Pipette (1) abstützt.
- - In a pipette housing ( 2 ) has a receptacle ( 3 ) for the syringe flange ( 21 ) and in a receptacle body ( 8 ) has a piston receptacle ( 9 ) for the syringe piston ( 25 ), the receptacles ( 3 , 9 ) having axial openings ( 4 , 10 ) for axially pushing the syringe flange ( 21 ) and syringe plunger ( 25 ) into their mounting positions in the pipette ( 1 ),
- - fastening means (12, 14) for reversibly fixing spraying flange (21) and syringe plungers (25) in their housings (3, 9), of which the syringe flange (21) engages behind,
- - The piston adjusting devices for moving the receiving body ( 8 ) in the pipette housing ( 2 ),
- - Which has an annular scanning device ( 6 ) with sensors distributed over the circumference ( 7 ) for information about a syringe and / or its state on an information carrier in the form of an annular ring arranged on the syringe flange with a plurality of axially directed scanning surfaces with an axial position
- - and which has an evaluation device for information read by the scanning device ( 6 ),
- - That the syringe ( 19 ) has no scanning surfaces, so that the sensors ( 7 ) of the scanning device ( 6 ) are not actuated when the syringe ( 19 ) with syringe flange ( 21 ) and syringe plunger ( 25 ) is arranged in the fastening positions,
- - And the syringe ( 19 ) outside of the sensors ( 7 ) on the pipette ( 1 ) is supported.
