3. Insert and push the sleeve onto the electrode, making sure that the black O-ring is fixed
inside the electrode body. Any excess of gel will be expelled from the end of the electrode
through the junction. Use a paper to clean it.
4. Shake the electrode down as you would do with a clinical thermometer to eliminate any air
bubbles inside the glass bulb. Remove the excess of gel and the electrode is ready for use.
MAINTENANCE:
When the electrode is not in use, you must store the electrode immersed in 3.5M KCl
solution, in order to stabilise junction potential. If left to dry, pH glass will not deteriorate.
In less than an hour, the pH electrode glass usually rehydrates. Replace the refilling gel
whenever is needed.
