Electrodes should be stored in electrode storage solution (025 192) between readings and for short–term storage. If storage solution is not readily available, liquid–filled electrodes can be stored in pH 4.0 buffer solution. To return an electrode to long term storage, prepare it in the same condition in which you received it; usually, this means simply moistening and replacing the end cap of gel–filled electrodes to PROTECT and keep the sensing membrane active. To store liquid–filled REFERENCE and combination electrodes, refill with electrolyte, COVER the FILL hole, and moisten and replace the protective plastic cap.

Important note: Never store an electrode in distilled or deionised water. This may lead to SLOW, sluggish response.
