Buffer Standard Solution is required to perform accuracy checks of pH apparatus for laboratory and field analysis.
Buffer Solution (p/n 2283561) is used to calibrate pH electrode at the pH value of 7.00±0.02 pH at 25°C for laboratory analysis. The volume of the solution is 20 L. Buffer Standard Solution is color-coded in yellow for visual identification. The solution is traceable to NIST pH scale. Bag-in-box (BiB) with collapsible inner bladder in white corrugated cardboard box is suitable for high volume pH testing in laboratories.
Storage conditions
Bag-in-box (BiB) storage conditions are between 10 °C and 25 °C protected from light. After opening, it is required to keep the solution for a maximum of 6 months.
