Buffer solutions play a substantial role in industrial and physiological processes. Buffer solutions of known and precise pH value allow to set the testing system to measure the samples of unknown pH more precisely and accurately. It is also used in the preparation of mobile phase in high performance liquid chromatography (HPLC).

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
