Temperature Influence on DuraCal pH Buffer 1.09 (Ref 238271)

Green circle icon with a dark navy lightbulb containing two interlocking gears, on a teal dotted background.

A prerequisite for an accurate pH calibration is the availability of suitable buffer solutions. Hamilton 1.09 DuraCal liquid buffer solution (Ref 238271) has an accuracy of +/- 0.02 pH units and a stability of 60 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.
