pH Electrode Filling vs Storage Solution: What Goes Where?

Not sure which pH electrode solution goes inside the probe and which belongs in the storage cap? This simple English guide explains filling solution vs storage solution with clear diagrams, bottle checks and manufacturer examples. Learn how to identify refillable and sealed gel-filled electrodes, why KCl concentration and solution codes matter, and what to do if the wrong liquid was used. We also cover calibration buffers, rinse water, recovery checks and shared-lab labelling.
