Overview

High quality pH electrodes from Sirius

Our pH electrodes are manufactured to a high standard. Each electrode is tested at Sirius following rigorous procedures to assure its performance characteristics.

Electrodes for use on GLpH are tested by doing at least four hourly automated calibrations, each time rinsing the electrode in pH7 buffer, then calibrating in a second pH7 buffer, then rinsing and calibrating in pH4 and pH10. Only electrodes with slopes greater that 98% and less than 0.6mV drift in pH7 between the final two calibrations are passed for sale.

Electrodes for use on GLpKa and PCA200 are tested by doing at least two blank titrations between pH 1.8 and 12.2. Only electrodes with all parameters within our latest Four-Plus specifications are passed for sale.

Electrodes for use on Vinotrate. Vinotrate electrodes are soak-tested in our laboratories before dispatch to customers.

Accessories

Electrode Length adaptor

For use with Sirius electrodes when using partition solvents such as chloroform and dichloroethane which are denser then water. The adaptor allows the electrode to be held in a raised position in the electrode holder. This keeps the electrode bulb in the water for better results.
