Der hülsenförmige Metallschraubverschluss ist gefenstert und hat einen elastischen Ring (5), der durch eine Üherwurfkappe (6) an die Pipettenwandung gepresst wird. Dadurch wird erreicht, dass eine im unteren Ende des Metallschraubverschlusses befindliche Dichtungsscheibe (7) einen sicheren Verschluss der Kapillaröffnung ermöglicht.The sleeve-shaped metal screw cap is windowed and has a elastic ring (5), which is pressed against the pipette wall by a cap (6) will. This achieves that one in the lower end of the metal screw cap The sealing washer (7) located allows a secure closure of the capillary opening.

Zur Untersuchung der Konzentration einer bestimmten Lösung wird der Becherteil mit Fällungsreagens, dem zu untersuchenden Stoff und einem Zusatz zur Einstellung eines bestimmten, gewünschten Fällungsmilieus (z. B. prj) gefüllt. Die Pipette wird am unteren Teil verschlossen und nach vollständiger Fällung in einer Labor-Zentrifuge geschleudert. Das Sediment wandert in die Kapillare.To study the concentration of a particular solution, the Beaker part with precipitation reagent, the substance to be examined and an additive for Setting of a specific, desired precipitation environment (e.g. prj) filled. the The pipette is closed at the lower part and, after complete precipitation, in a Laboratory centrifuge spun. The sediment migrates into the capillary.

Aus der Höhe der Sedimentablagerung kann rechnerisch die Konzentration eines bestimmten anorganischen oder organischen Stoffes in der zu untersuchenden Lösung ermittelt werden.The concentration can be calculated from the height of the sediment deposit of a certain inorganic or organic substance in the to be examined Solution to be determined.
