pH Buffer Solutions For Calibration
The calibration of pH and Redox electrodes has never been easy. All calibration procedures assume that the labelled values of the calibration buffers are correct. But buffer values can change over time and so can your results. Hamilton guarantees DURACAL pH buffers for 5 years after the date of manufacture. The pH 9.21 and pH 10.01 buffers are even stable in air.
- Convenient 250 ml and 500 ml plastic bottle with built-in calibration compartment.
- Economical, since only about 20 ml of buffer is used per calibration.
- Actual value is determined by a DKD laboratory, accredited for pH measurement.
- First class certificate with traceability to international standards.
- Certificates available at on demand.
