Hanna pH 13.00 Technical Calibration Buffer (500 mL)

Hanna Instruments pH 13.00 Technical Calibration Buffer Solution is engineered for reliable and precise calibration of pH meters and electrodes. Presented in a 500 mL bottle, this buffer is NIST traceable and supplied with a Certificate of Analysis, guaranteeing batch-level quality and traceability. The solution achieves an accuracy of ±0.01 pH at 25°C, supporting even the most rigorous laboratory, research, or industrial needs.

This technical buffer features a lot number and expiration date on the label, and its tamper-proof, air-tight bottle ensures integrity and stability for up to 5 years if unopened. Each bottle is printed with a temperature-to-pH chart, allowing users to compensate for calibration changes during temperature variation. The high alkalinity pH 13.00 buffer is specially formulated for technical applications requiring elevated pH values, such as environmental testing, water and wastewater treatment calibration, electrochemical research, and industrial process control.
