    Comments about Cole-Parmer pH electrode, combination, double-junction, gel filled:

    Adequate pH probe for use in soil solutions. Seems to be fairly rugged and probably will serve well as a good probe for student use.

    Comments about Cole-Parmer pH electrode, combination, double-junction, gel filled:

    Works fine, calibrates easily. With heavy use I have had to replace the probe about every 9-12 months but the probe is used mulitple times daily.
    I would highly recommended it.

        The perfect electrode for routine use in the lab or field. I really appreciate having the electrode shipped pre-filled and pre-wetted so that i could open the box, plug the electrode into my meter and begin calibrating and measuring within 1 minute. The electrode is stable and durable and a great value.

          • Q:

            I need micro pH electrode to measure solutions in eppendorf 500ul microtube.
            How can I find out which one is fit, the tip should be 3.5-4mm in diameter.

            Thank you, Natalia

          • Q:

            We have been using the Cole-Parmer SKU# 05997-10 electrode. They aren't very sturdy and have to be replaced often. The most recent one was put into use on 1/6/16 and has never worked correctly. LOTS of drift. The electrode is used daily with water based biocides. Is the double-junction, gel-filled electrode a better fit for us? We have the Oakton 510 pH meter.

            Thanks!

              A:

              Yes, double junction electrodes are longer-lasting, sturdier electrodes when compared to the single junction electrodes. For a more accurate recommendation, please contact us.

              A:

              A double junction electrode will last longer than a single junction electrode. When the pH probe is not in use, it should be in storage solution. This will allow for a longer probe life.

          • Q:

            This electrode was left out in the open air for a year. Is it still good? Do I need to "recondition" it somehow?

            • STAFF EXPERT

              A:

              Conditioning the electrode would be my first step. Remove the protective cap or rubber boot from the bottom of the sensor and rinse the electrode with distilled or deionized water. Place the electrode in a beaker containing one of the liquids listed below (in order of ionic ability to condition the electrode). Soak for 20 minutes in either a 3.8 M or 4.0 M KCL, 4.0 pH buffer, or 7.0 pH buffer. Note: Never condition a pH electrode in distilled or deionized water. Long term exposure to pure water will damage the special glass membrane. After conditioning the sensor for 20 minutes, rinse the electrode with distilled or deionized water. The electrode is now ready for calibration and to measure pH.

            • STAFF EXPERT

              A:

              When used with a meter, the meter sends its own excitation signal. That signal depends on the meter being used.

              You ideally want to keep it in electrode storage solution or pH 4 Buffer when not in use.

            What is the difference between a single junction and double junction PH probe and what would dictate their different applications?

            • STAFF EXPERT

              A:

              Single junctions are primarily used in pure aquatic substances where there is little concern for contamination. Double junction electrodes tend to be used in "dirtier" applications where there is concern of clogging. Double junctions also tend to be more stable.
