Description
The SS-25 solution is specifically designed as an electrode storage solution for pH and ORP electrodes.
- Purpose: Its primary function is to keep the sensitive glass membrane and reference junction of pH and ORP electrodes hydrated when the probe is not in use. This prevents the electrodes from drying out, which can cause irreversible damage and lead to inaccurate measurements or premature failure.
- Composition: The SS-25 solution is a clear, colourless aqueous solution primarily composed of Potassium Chloride (KCl). It’s typically a concentration of less than 4M KCl. This composition helps maintain the proper ionic environment around the electrode membrane.
- How it’s Used: It’s used to dampen the sponge located within the probes storage cap. A few drops of SS-25 solution should be applied to the sponge each time the cap is removed and replaced, ensuring the sponge remains moist.
- Importance: Consistent use of SS-25 solution for storage is crucial for:
- Maintaining Electrode Performance: Ensures the electrodes remain responsive and accurate.
- Extending Electrode Lifespan: Prevents damage that can occur from drying out, thereby prolonging the useful life of the pH and ORP sensors.
- Ensuring Ready-for-Use State: Keeps the electrodes conditioned so they are ready to provide accurate readings as soon as the probe is deployed.
- Safety Information: As with any chemical solution, it’s advised to handle SS-25 with care and follow any provided safety data sheets (MSDS). General precautions include avoiding inhalation, skin, and eye contact, and rinsing thoroughly with water if contact occurs. It’s considered generally safe when handled according to good laboratory practices.
In essence, SS-25 is a vital maintenance item for your electrode, directly contributing to the longevity and accuracy of your pH and ORP measurements.
