pH-Puffer
pH-Pufferlösungen sind für die routinemäßige Kalibrierung von pH-Metern unerlässlich, um den genauen pH-Bereich einer Säure oder Base zu erfassen. Gebrauchsfertige Lösungen vermeiden den Zeitaufwand, die Kosten und die Kontaminationsrisiken beim Ansetzen von Puffern. pH-Puffer können verwendet werden, um schwache Säuren, konjugierte Basen, starke Säuren, Blut-pH usw. zu identifizieren. Mit farbigen und farblosen pH-Pufferoptionen können Forscher effizient die richtige Indikatorlösung für jeden Test auswählen. Pulverpäckchen und Beutel ermöglichen es Laboren, konzentrierte Substanzen über längere Zeiträume zu lagern, ohne beeinträchtigt zu werden.

The measurement of the pH value is one of the most frequently and universally made measurements in science.
What is often not fully understood is the fact that a large number of problems related to pH measurement is the
correct selection, care or maintenance of the electrodes with particular emphasis on the reference electrode.
