The use of a separate Reference Electrode is required.
The probe is usually used with the 8-702 reference electrode in series.
Calibration is done by passing pH buffers through the two electrodes and then calibrating on the pH meter
Using any electrode in solutions containing protein requires the electrode be rinsed with an enzyme cleaning solution.
After each use, we recommend cleaning our electrodes with Terg-a-zyme (Alconox, Inc.) or a chromic/sulfuric acid glass cleaning solution by submerging the electrodes for a couple of minutes in order to remove all protein from the glass and reference junction.
This will prolong the useful life of the electrodes.
Always clean the microelectrode before storing:
- Long-term (over 2 weeks): Return the probe to its original container and prepare it in the same condition in which you received it. Usually this means simply moistening the sponge located in the bottom of the protective glass tube with pH 4 buffer.
- Short-term: The probe can be left in an acid pH buffer solution (pH 4.01).
