Abstract

In einer Kolbenspritze (1) sitzt im Uebergang (8) zwi­ schen Zylinder (2) und Kanüle (4) ein ferromagnetischer Profilkörper (9) mit vielfältigen Funktionen: Beim Einsaugen einer Flüssigkeit verhindert er Turbulenzen im Uebergang (8) und die damit verbundene Bildung von Gasblasen; beim Ausstossen hilft er, Schmutz im Uebergang (8) nach unten wegzuspülen; dazwischen wirkt er durch von aussen veran­ lasste Vertikalbewegungen als Magnetrührer.
Diese Funktionen werden unterstützt durch eine schräg ansteigende Kolgenstirnfläche (13), im Zusammenwirken mit einer seitlichen Oeffnung (5), welche mit einer Entsorgungs­ einrichtung in Verbindung steht.
Hauptanwendung: Schnelles, blasenfreies und daher mengengenaues Uebertragen flüssiger Proben, z.B. Blutplas­ ma, in mehrere Prozessgefässe von Analyseautomaten.
