Detaillierte Programminformation unter

Rheologische Messungen und Stabilitätsuntersuchungen mittels STEP®-Technologie gewinnen in der F&E und in der QS immer mehr an Bedeutung. Die rheologischen Eigenschaften von dispersen Systemen und die Adsorptionsvorgänge an Ihren Grenzphasen sind ausschlaggebend für deren Stabilität und Verarbeitungsverhalten.


  • Grundlagen und Anwendungen von rheologischen Messmethoden (3D-Rheologie)
  • Tensiometrie und Rheometrie von Grenzphasen (2D-Rheologie)
  • Rheooptische Methoden und Röntgenkleinwinkelstreuung
  • Stabilitätsmessung mittels STEP®-Technologie von dispersen Systemen
  • Partikelgrößenverteilung mittels dynamischer Lichtstreuung (DLS) und analytischer Zentrifugation (AC)
  • Vorträge über Anwendungen aus verschiedenen Branchen
  • Fallstudie zur Vertiefung der Grundlagen
