element and reference junction must not dry out. Always clean the

electrode before storing it.

Short-term storage (up to one week): Soak the electrode in pH

electrode storage solution, Cat. No. 910001. To prevent crystallization

of the filling solution, cover the fill hole whenever the electrode is being

stored and open the fill hole when calibrating and measuring.

Long-term storage (more than one week): Fill the electrode

and securely cover the filling hole. Cover the electrode with the

protective glass tube containing a few drops of storage solution. Before

returning the electrode to use, prepare it as a new electrode.

• Used in gels or smaller sample volumes
