A prerequisite for an accurate pH calibration is the availability of suitable buffer solutions. Hamilton 11.00 DuraCal liquid buffer solution (Ref 238278) has an accuracy of +/- 0.05 pH units and a stability of 24 months. The pH value of the buffer is affected by changing temperature. The effects of temperature from 5 to 50°C is shown below in 1-degree increments.
