Puffer und Standards

Wasserstoffionenpuffer, bestehend aus einer Mischung aus schwacher Säure und ihrer konjugierten Base oder umgekehrt, dient zur Stabilisierung des pH-Werts; zudem Verdünnungsmedien, Waschlösungen und Standardlösungen für eine Vielzahl wissenschaftlicher Kalibrierungszwecke.

Die Puffer zur Kalibrierung von pH-Wert-Messgeräten können zertifiziert und/oder NIST-rückführbar (National Institute of Standards and Technology) sein. Diese Puffer können auch zur einfachen Identifizierung farbcodiert sein:

  • Rot: pH-Wert 4,0
  • Gelb: pH-Wert 7,0
  • Blau: pH-Wert 10,0
