MI-401F Reference Electrode with Glass Barrel and Frit Junction
MI-401F Reference Electrode with Glass Barrel and Frit Junction
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 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 to 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 2 weeks): Return the probe to its original container and prepare it in the same condition in which you received it. Usually this means simply moistening the sponge located in the bottom of the protective glass tube with pH 4 buffer.
- Short-term: The probe can be left in an acid pH buffer solution (pH 4.01).
