MERCURY DISCLOSURE: To function properly, this electrode necessarily contains a small amount of mercury. The maximum amount of mercury in this electrode is 0.3 grams. See SDS Forms tab for safety information.
Avoid using this reference electrode with the following: chloride ion, perchlorates, and non-aqueous/organic solvents
The junction at the lower end of the reference electrode is a ceramic frit that should be kept wet at all times. If frit dries out, soak overnight in distilled water. More information about care, storage, and usage can be found in the product information sheet, which you can download from the Documentation tab.
A small vial containing saturated K2SO4 electrode filling solution is included with the single junction mercury sulfate reference electrode.
