With a defined pH value of 9,21, it serves as a reliable reference point for checking and adjusting pH meters and electrodes in the alkaline range. The 6 x 250 ml configuration provides convenient working stock for laboratories that calibrate several instruments or renew buffer solutions frequently during daily operation.

Originating from Switzerland and offered by manufacturer Mettler-Toledo OnLine, the product forms part of the established pH buffer solution range used in chemical, pharmaceutical, food, and environmental laboratories. Individual 250 ml bottles suit open-bench calibration stations, while the six-bottle pack supports uninterrupted measurement workflows and reduces the need for frequent single-unit reorders.
