Product Description

The Apera Instruments AI1115 pH Calibration Buffer Solution Kit includes three 8 oz (240 mL) bottles of color-coded pH buffer solutions: pH 4.00, pH 7.00, and pH 10.01.
Each solution is standardized against NIST-certified pH references with an accuracy of ±0.01 pH at 25 °C (77 °F), making the kit ideal for the calibration of all types of pH meters, from laboratory to field applications.

Because pH values are temperature-dependent, a temperature/pH reference chart is conveniently printed on each bottle label to support accurate calibration under different conditions.

All solutions are double-sealed, non-hazardous, and designed for safe, unrestricted shipping. The solutions offer a 2-year shelf life, with the expiration date clearly marked on each bottle. MSDS documentation is available for download.
