This clever LDPE bottle is designed to be filled with a storage solution and then fitted to your electrode where it seals around the base. This ensures the electrode is correctly stored and the membrane is kept hydrated, to keep your electrode in great condition so it is ready to use as soon as you need it.
We recommend a mixture of 3 molar KCl solution and pH 4 buffer (non-coloured), or a pH electrode storage solution such as the Reagecon brand solutions.
