The HI70009P buffer solution is a standard calibration solution at pH 9.18 designed for calibrating pH measuring instruments. Each sachet is identified by a lot number and an expiration date to ensure complete traceability.
The HI70009P solution is formulated to offer long-term stability. Hanna standard solutions are designed for a shelf life of up to 5 years from the date of manufacture if the sachet is unopened.
The solution is manufactured according to ISO 3696 and BS3978 standards, using pure salts and demineralized water, with certified measuring equipment and Class A glassware, in a temperature-controlled environment. The reported values have an accuracy of ± 0.01 pH at 25 °C and refer to NIST standards.
Convenient disposable sachet, suitable for users who calibrate infrequently and for field use.
Each sachet contains a fresh solution, with packaging protecting the solution from UV rays that could alter the buffer value.
The sachets are designed for easy identification according to the pH value. The solution contains no dyes that could stain the reference cell of a pH electrode.
