Zur Zufuehrung einer Probe zu einem Verbraucher, sind koaxial zueinander ein feststehendes und ein drehbar gelagertes Teil angeordnet, die beide axial gerichtete Kanaele aufweisen, durch die eine Traegerloesung und zu dosierende Probenfluessigkeiten gefuehrt werden, wobei von den im drehbaren Teil nach aussen weisenden Enden der Kanaele jeweils Paare durch flexible Leitungen verbunden sind, so dass eine paarweise funktionsmaessige Zuordnung der im feststehenden Teil befindlichen Kanaele hergestellt wird. Der Kanal im feststehenden Teil, der die zu dosierende Probenfluessigkeit aufnimmt, steht ueber eine Druckpumpe mit einem Probengefaess in Verbindung. Von dem Verbraucher besteht sowohl eine umschaltbare Verbindung zu dem Kanal, dem durch eine der flexiblen Leitungen ein die Traegerloesung fuehrender Kanal zugeordnet ist, als auch zu einem Gefaess fuer die Traegerloesung. Mit der Erfindung wird erreicht, dass trotz verminderter Oberflaechenqualitaet der gleitenden Dichtflaechen der Eintritt von Luft in die Kanaele ausgeschlossen wird. Fig. 1
