pH Calibration

These electrodes are standardized in two pH buffers. Follow the procedure recommended by the manufacturer of your pH meter for calibrating your pH meter with our electrodes.

Optimum Response Time: Optimum response time will be obtained after the probe has been exercised in two buffer solutions. Place a pH 4.01 buffer or equivalent in a beaker and a pH 6.86 buffer or equivalent in a second beaker. Immerse the electrode in the pH 4.01 buffer allowing 15-20 seconds for equilibration. Rinse the electrode with distilled water and immerse in the pH 6.86 buffer in the same manner. Do this several times.

Handling

Although the electrode may appear to be indestructible, always handle the electrode with the same care you would use with other glass electrodes.

Cleaning

Clean the electrode well after each use. When using the electrodes in solutions containing protein, they should be rinsed with an enzyme cleaning solution such as Terg-a-zyme (Alconox, Inc.) or a glass cleaning solution after each use for a couple of minutes to remove the 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 electrode 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 distilled water.

Short-term: The electrode can be left in an acid pH buffer solution, e.g. pH 4.01.

In addition, we can supply these probes with either a titanium sheath and incorporate temperature sensors. We can supply them to any reasonable length. Ideal for automation applications including ChemSpeed systems.
