Abstract

Dosiervorrichtung für Flüssigkeiten mit
- einem Grundkörper,
- am Grundkörper angeordneten Mitteln zum Halten mindestens einer Pipettenspitze mit ihrer oberen Öffnung in abdichtender Verbindung mit einer Durchgangsöffnung am Grundkörper und einer im Grundkörper angeordneten Verdrängungseinrichtung mit einer Verdrängungskammer, einem darin beweglich angeordneten Verdrängungsorgan und einer kommunizierenden Verbindung mit der Durchgangsöffnung oder
- am Grundkörper angeordneten Mitteln zum Halten mindestens einer Spritze mit einem Spritzenzylinder in lagefester Beziehung zum Grundkörper und mit einem in dem Spritzenzylinder verschiebbaren Spritzenkolben und mit einem mit dem Spritzenkolbenmechanisch kuppelbaren Kupplungsmittel im Grundkörper,
- am Grundkörper angeordneten Mitteln zum Lösen der Pipettenspitze oder Spritze von den Mitteln zum Halten mit einem manuell betätigbaren Betätigungsorgan zum Betätigen der Mittel zum Lösen, ohne das dabei das Verdrängungsorgan oder das Kupplungselement bewegt werden
- einem am Grundkörper angeordneten Sensor zum Erfassen einer Betätigung der Mittel zum Lösen oder des erfolgten Lösens der Pipettenspitze oder Spritze,
- einem ansteuerbaren Antrieb, der mit dem Verdrängungsorgan oder den Kupplungsmitteln wirkverbunden ist,
- Eingabemitteln zum Steuern des steuerbaren Antriebs,
- elektrischen Steuerungsmitteln, die mit dem steuerbaren Antrieb, den Eingabemitteln und dem Sensor elektrisch verbunden sind und die so beschaffen sind, dass der steuerbare Antrieb, wenn der Sensor eine
Betätigung der Mittel zum Lösen oder das erfolgte Lösen der Pipettenspitze oder Spritze erfasst, das Verdrängungsorgan oder die Kupplungsmittel in eine Grundposition verlagert.
