ELECTRODE MAINTENANCE
PREPARATION
The FC 301B fluoride electrode is shipped dry to
prolong its life. The HI 5313 reference electrode
instead should be maintained wet with storage solu-
tion in the protective cap.
Remove the protective cap from the HI 5313 reference
electrode.
Any salt deposit around the bottom of the electrode is
normal and it will dissolve if rinsed with water.
If the junction of the HI 5313 reference electrode is
dry, soak the tip in HI 7082 solution for at least one
hour prior to operation.
If the bulb of the FC 301B fluoride electrode is dry, soak the tip in
HI 70702 (10 mg/L fluoride) solution for at least three hours
before using it.
STORAGE
The FC 301B fluoride electrode must be stored dry to prolong its life.
After use, rinse it with deionized water, dry it attentively with a non-
abrasive cloth and store it dry.
The HI 5313 reference electrode should be kept wet for a rapid
response. After use, rinse the electrode with deionized water and
store it with a few drops of HI 7082 solution in the protective cap.
PERIODIC MAINTENANCE
Periodically check electrodes and cables. The cables should be intact
and show no sign of wear and tear. The electrode bulb and stem
should present no cracks (in which case it, must be replaced). The
connectors must be clean and dry. Rinse the reference electrode with
deionized water to wash away any salt deposits that there might be.
REFERENCE ELECTRODE CLEANING
General:
immerse the reference electrode in HI 7061 general
cleaning solution for about one hour.
Protein: immerse the reference electrode in HI 7073 pro-
tein cleaning solution for about 15 minutes.
Oil and fat: rinse the electrode with HI 7077 cleaning solution.
