Maintenance of reference electrode

Reference electrode with c(KCl) electrolyte for cyclic voltammetric stripping

Here you will learn all about the maintenance of your reference electrodes with the ordering numbers 6.0728.x30 and 6.0728.x40.

Double-junction ag/AgCl reference electrode voltammetry
The electrodes with the ordering numbers 6.0730.x00 are maintenance-free. However, the gel filling must not dry up. If the gel reference electrode is not used, store it in the supplied storage vessel filled with c(KCl) = 3 mol/L.


  • My reference electrode has dried out. Can I regenerate it again?

  • Until now, I have always used diluted H2SO4 as a bridge electrolyte. Can I use another electrolyte instead of KNO3?

  • How often do I need to change the reference electrolyte?

  • How often does the bridge electrolyte need changing?
