Description
HI-70300-050 Storage solution for pH and ORP electrodes, 500ml – Groline Range
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 deionised water. The Hanna Instruments storage solution is specifically formulated to minimise 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 HI-70300-050 GroLine storage solution for at least one hour before taking measurements.
* Never store pH or ORP electrodes in distilled or deionised water. Doing so will shorten the life of the sensor.
