Intended Use

Der Titrations-Probenwechsler ermöglicht die Durchführung von Serien-Titrationen mit automatischem
Probenwechsel. Er ist einsetzbar für alle Proben, die in einem offenen Becherglas durchgeführt werden
können. Mit einem dafür geeigneten Titrierkopf lassen sich CSB-Titrationen in den genormten
Reaktionsgefäßen nach DIN 38 409, Teil 41 direkt durchführen. Der Probenwechsler wird über die
RS-232-C-Schnittstellen vom Computer bzw. von Titratoren gesteuert. Er besitzt einen eingebauten
Magnetrührer.
