You can make your own ph pen probe storage solution (3 molar KCL) with ph 4 buffer solution + potassium chloride.
Mix 1g potassium chloride (KCL) per 100ml ph buffer 4 solution to make 3 molar kcl storage solution. The gel dries out quickly if left in open air or is stored in reverse osmosis or tap water leeches potassium chloride ions as the probe tries to make equilibrium. Storing the probe submerged in 3 molar kcl storage solution is best (better than few drops in cap) for years of life out of the ph pen. Change the storage solution every 2-3 months. Not a scientist or student but a grower using common sense.

Electrodes should always be stored in aqueous and ion-rich solutions. This ensures that the pH-sensitive gel layer which forms on the pH glass membrane remains hydrated and ion rich. This is necessary for the pH membrane to react in a reliable way with respect to the pH value of a sample. Short term storage: In between measurements or when the electrode is not being used for brief periods of time, it is best to keep the electrode in a holder contain­ing its inner electrolyte solution (e.g. 3 mol/L KCl), or in a pH 4 or pH 7 buffer. Ensure that the level of solution in the beaker is below that of the filling solution in the electrode. For long term storage: Keep the electrode wetting cap filled with the inner electrolyte solution, pH buffer 4 or 0.1 mol/L HCl. Make sure that the fill­ing port for reference and combination electrodes is closed to avoid loss of the electrolyte solution through evaporation, which can cause the formation of crystals within the electrode and junction. Never store the electrode dry or in distilled water as this will affect the pH-sensitive glass membrane and thus shorten the lifetime of the electrode.

Are you using the terms "diaphragm" and "junction" interchangeably?

[@METTLERTOLEDOLaboratory]

Hi,
Yes, junction and diaphragm have been used interchangeably in the video because both serve the same purpose of allowing the outflow of reference electrolyte into the sample compartment.
