pH-Pufferlösungen
pH-Pufferlösungen werden häufig zur Kalibrierung von Messgeräten bzw. Elektroden genutzt. Sie werden zudem eingesetzt, um den pH-Wert einer Lösung während einer Messung, Reaktion oder biologischen Anwendung konstant zu halten. Im Online-Shop von Th. Geyer finden Sie pH-Pufferlösungen für verschiedenste Anwendungen. Das Sortiment enthält u.a. pH-Puffer mit und ohne Farbcodierung, in twin-neck Flaschen zur einfachen Dosierung, in praktischen Polytainern, referenziert bei 20 °C oder 25 °C, in Siegelrandbeuteln, rückführbar auf Standardrefernzmaterial von NIST oder auf DIN Normen, sowie technische Lösungen und Puffer mit höchster Genauigkeit. Ebenso finden Sie biologische Pufferlösungen.
