MI-403 Double Junction Dip-type Reference Electrode

These electrodes are designed for use with any pH or ion-selective electrode.  They utilize Ag-AgCl internal reference electrodes with 3M KCl filling solution.  They may be used for many weeks before refilling is required.  Each reference electrode includes 2 inner reference barrels and a bottle of 3M KCl.

  • CALIBRATION

    This is a Ag/AgCl reference half-cell probe. The calibration is done in combination with the ion-specific probe used.

     

     

     

  • CLEANING

    Using any electrode in solutions containing protein requires the electrode be rinsed with an enzyme cleaning solution.

     

    After each use, we recommend cleaning our electrodes with Terg-a-zyme (Alconox, Inc.) or a chromic/sulfuric acid glass cleaning solution by submerging the electrodes for a couple of minutes in order to remove all protein from the glass and reference junction.

     

    This will prolong the useful life of the electrodes.

  • STORAGE

    Always clean the electrode before storing:

     

    • Long-term (over 4 weeks): Drain the solution and rince with DI water

     

    • Short-term: The probe can be left in any solution to keep the tip from drying out.
