General description
RE-5B Ag/AgCl (3M NaCl) Reference Electrode with Flexible Connector
TESTING THE PERFORMANCE OF Ag/AgCl
REMOVING THE SHEATH: Every Ag/AgCl reference electrode is shipped with a yellow plastic sheath that covers the porous frit and slows drying. Immediately remove the sheath upon receipt and store electrode in appropriate solution. It’s recommend soaking the tips in the 3M salt solution for about an hour after removing the protective cover. Please check that there are no bubbles on the electrode frit. If there are bubbles on the frit on the inside of the electrode, you will need to flick or tap the side of the electrode near the frit to dislodge the bubbles so that they rise to the top of the electrode. Bubbles on the frit can cause an unsteady signal and damage the electrode. The redox potential for the Ag/AgCl (3M NaCl) Reference Electrode is +0.209 V (vs. NHE). Be extremely careful when removing the plastic sheath from the reference electrode. DO NOT roll the plastic down and pull off. The best method is to cut the length of the plastic sheath with scissors and peal the sheath off the electrode. Start with a small cut at the upper edge of the sheath, pull to the side, and continue to cut and peal to the tip. A scalpel may be used, but there is greater chance of damaging the heat-shrink tubing.
DISLODGING BUBBLES: Bubbles lodged in the tip may prevent electrical contact with the electrolyte and may damage the working electrode. Bubbles can be dislodged by holding the top of the electrode with one hand and tapping the electrode near the frit tip until the bubbles rise to the top.
REGENERATING THE
STORING REFERENCE ELECTRODES: After the sheath is removed, store the electrode tip in 3 M NaCl or 3M KCl solution. We do recommend storage vial for efficient storage. Only the tip needs to be immersed in the storage solution; the connecting pin needs to be kept dry to minimize corrosion. The reference electrodes are easily ruined by drying and will naturally change with use due to the ion and solvent transport across the porous frit. This rate of change is a function of the difference in composition between the sample solution vs. the filling solution and the amount of time not immersed in the storage solution.
