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.
