8-720 Flow-thru Carbon Dioxide Electrode with 1/8" Fittings

These miniature electrodes are ideal for monitoring Carbon Dioxide flow such as water, blood, urine, physiologic fluids, etc. They feature fast response and require less than a drop.  Each electrode is supplied with 6 assembled membranes and a bottle of electrolyte solution.

  • CALIBRATION

    Calibration is done with two standard gases bubbled through a liquid. Typically 5% and 10% CO2 balanced Nitrogen. The probe responds slugishly to low CO2 levels, so to help with repsonse time, the amount of exposure to ambient should be limited in use.

  • 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.)  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).
