Temperature Influence on DuraCal pH Buffer 9.21
A prerequisite for an accurate pH calibration is the availability of suitable buffer solutions. Hamilton 9.21 DuraCal liquid buffer solutions have an accuracy of +/- 0.02 pH over 60 months. Like all aqueous solutions, 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.
