Singlet Single-Use pH Buffer Kit is required for pH instrument calibration for laboratory and field analysis.
pH Buffer Standard Solution (p/n 2769920) is used to calibrate pH electrode at the pH value of 4.01 & 7.00±0.02 pH at 25°C. 10 sealed foil pouches of 4.01 pH and 10 packs of 7.00 are sealed in each Singlet Single-Use pH Buffer Kit. The volume of each singlet is 20mL. The solution is color-coded and NIST-traceable. Singlet Solution Packs can be used only for laboratory and field analysis.
Storage conditions
pH Buffer Standard Solution storage conditions are between 15 °C and 25 °C protected from light.
