Hanna pH 7.413 @ 25°C Millesimal Calibration Buffer, 500 mL - HI6074

The Millesimal pH 7.413 Calibration Buffer Solution is specifically designed for laboratories and industrial environments that demand the highest possible accuracy and precision in pH meter calibration. With a pH value of 7.413 at 25°C, this buffer ensures millesimal (0.001) resolution and an exceptional accuracy of ±0.002 pH, conforming to the stringent requirements for critical analytical procedures.

The solution is NIST traceable and comes with an authenticated Certificate of Analysis, giving users confidence in traceability and compliance. Each 500 mL bottle is securely sealed and clearly marked with the lot number, expiration date, and a temperature compensation chart for actual pH values at various temperatures. This information is vital for maintaining calibration accuracy in varying laboratory conditions. The buffer’s specially formulated composition provides an extended shelf life of up to five years when the bottle remains unopened.
