pH Calibration Buffer Solution Kit (pH 4.00, 7.00, and 10.01) APERA

The Apera Instruments AI1109 pH Calibration Buffer Solution Kit is a comprehensive three-point calibration system containing three 450 ml bottles of color-coded pH buffer solutions (pH 4.00, pH 7.00, and pH 10.01), one 120 ml bottle of 3M KCl storage solution for pH/ORP electrodes, and Apera's proprietary Cal reference guide. This integrated system eliminates confusion during the calibration process by organizing all solutions in a single kit. The color-coded buffer solutions are standardized according to NIST-traceable pH references within ±0.01 pH at 25°C (77°F). Ideal for calibrating all types of pH meters and analyzers. Since pH values are temperature-dependent, a temperature/pH reference table is provided on the bottle label for accurate reference. The included 3M KCl storage solution helps maintain the sensitivity and accuracy of pH probes during storage periods. All solutions feature dual seals, are not subject to DOT shipping restrictions, and carry a 2-year shelf life with expiration dates clearly marked on bottles. MSDS documentation is available for download.
