  1. GroLine Electrode Storage Solution
    $24.20

    Please note - All prices are inclusive of GST and not all items are stock items, if you require an immediate solution please contact us today.

    HI70300-023 is a GroLine storage solution prepared with reagent grade chemicals that can be used to ensure optimum performance of your pH and ORP electrodes. It is necessary to store a pH electrode in a solution in order to keep the glass membrane of the pH electrode hydrated. Ideally a storage solution should be used; never store an electrode in distilled or deionized water. The Hanna Instruments storage solution is specifically formulated to minimize microbial growth and to prevent any diffusion/osmotic effects from storing a probe in a solution with the highly concentrated inner reference electrolyte. Storing your pH and/or ORP electrodes in a storage solution will also keep the junction clear. Maintaining the hydrated layer and clear junction will help to ensure a fast and reliable measurement. In the case of cleaning your pH electrode in one of our cleaning solutions, we recommend soaking the electrode in the HI70300-023 GroLine storage solution for at least one hour before taking measurements.

  6. HI8093
    $138.33

    Please note - All prices are inclusive of GST and not all items are stock items, if you require an immediate solution please contact us today.

    HI8093 is a pH and ORP electrode fill solution that is supplied in a FDA compliant bottles. Each bottle contains 3.5M KCl + AgCl, which is specifically made for single junction electrodes. The electrolyte level in refillable electrodes should be checked before performing any measurements. If the level is low, refill with the proper electrolyte solution to ensure optimum performance. This simple maintenance helps guarantee adequate head pressure to promote the flow of reference electrolyte into the sample being measured.
