Temperature Influence on DuraCal pH Buffer 10.01
pH can change based on the temperature. This article lists the expected pH values from 5 to 50°C for Hamilton's 10.01 DuraCal pH liquid buffers (Refs 238321, 238223, 238923, 238187, 238898).
A prerequisite for an accurate pH calibration is the availability of suitable buffer solutions. Hamilton 10.01 DuraCal liquid buffer solutions are considered "Certified Reference Material" and are tested by a 3rd party lab - DAkkS - against primary reference solutions from PTB and NIST. 10.01 liquid buffers 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.
