M.C. Miller Gen II Leak Stop Gel was developed for situations in which electrodes may leak CuSo4 solution in a quantity which is unacceptable. This often arises when an electrode is stored in a vehicle where the heating and cooling of night and day expands and contracts the CuSo4 liquid, forcing it through the ceramic plug. This leaves a messy residue of CuSo4 crystals behind. This situation of unwanted leaking electrodes is greatly reduced or eliminated when Gen II Leak Stop Gel is used. The gel is too thick to be forced out the end of the electrode during normal heating and cooling cycles, preventing the leakage from occurring.
New, improved Leak Stop Gel for use with any MCM electrode.
Preparation for Use
Leak Stop is a saturated CuSO4 solution. If it is desirable to verify that the solution is saturated, a few (half a teaspoon) copper-sulphate crystals may be added. This can be done immediately after Leak Stop has been added to the electrode but before hardening has started. With this done there will always be crystals visible to insure a saturated CuSo4 solution.
Removing Gel from Electrode
Replace the gel once the electrode has become used, contaminated, cloudy or varies from freshly prepared standard by 15 mV. Internal company guidelines may dictate a different millivolt variance. The Miller Gen II Leak Stop Gel behaves like a CuSo4 electrode filled with deionized water. After time and repeated use the electrode may become contaminated. When this occurs, the gel must be removed and the electrode cleaned to a bright shiny state. To remove the gel, run hot water into a bowl and submerge the electrode for 10 - 15 minutes. The Gen II Leak Stop Gel will liquefy.
The liquid Gen II Leak Stop Gel may be discarded using proper disposal methods. Rinse out the electrode tube and remove the copper element. With the rod removed, it can be sanded with brown sand paper to remove oxidation. Rinse thoroughly with deionized water and reassemble. The electrode can be refilled with Gen II Leak Stop Gel as outlined above.
Note: Leak Stop is a gel and therefore does not soak through the ceramic tip as much as a normal copper-sulphate solution. The side effect of this gain is that the ceramic tip when used in a very arid condition may dry out. This problem is easily overcome by submerging the ceramic tip of the electrode into a cup of tap water for 5 seconds. This will re-wet the tip and the electrode will work as desired.
