How’s best to store a Redox electrode?

Like pH electrodes, redox electrodes are stored with the electrode tip submerged in 3.0 Molar KCL (potassium chloride). The TRUEscience redox electrodes are shipped with a soaker bottle around the tip of the electrode, keep this for long term storage and make sure it is topped up with electrode storage solution when in use.
For electrode storage on a laboratory bench whilst attached to the TRUEscience SMART Cap, use the electrode storage stand to keep the electrode well conditioned when not in use. The SMART Clip will hang the Cap and electrode on the stand, and suspend the tip of the probe in the storage solution. This ensures the electrode does not get damaged by hitting the bottom of the container. The unique stand will keep the glass bulb in conditioned use with minimal storage solution wastage.
Dirty, contaminated electrodes will slow down the response rate and may cause the readings to drift. Make sure your redox electrodes are thoroughly rinsed before and after use to make sure no contamination accumulates. There are a range of different cleaning solutions which can be applied to the electrode based on contaminant for example 0.1 molar HCL can be used for oil and grease deposits, pepsin or HCL can be used for blockage due to proteins. ORP/Redox electrode tips (Platinum rods or discs) may need additional cleaning from time to time with Crocus (mild abrasive) paper.
