Hanna Electrode Storage Solution - HI 70300 - For pH Electrode Preservation

Keep Your pH Electrode Ready for Fast, Accurate Readings Every Time

Hanna HI 70300 Electrode Storage Solution is formulated to keep the glass bulb and junction of your pH electrode properly hydrated between uses. Storing your electrode dry causes the glass membrane to dehydrate, which slows response time and degrades measurement accuracy. A few drops of HI 70300 in the protective cap maintains the electrode in peak condition and ensures a fast, reliable response from the first measurement.

Key Features & Benefits

• Prevents junction clogging - Proper storage in HI 70300 minimizes the risk of junction drying and clogging that leads to sluggish or inaccurate readings.
• Maintains fast response time - Hydrated glass bulb and junction deliver quick, stable pH readings at the start of each measurement session.
• Extends electrode lifespan - Correct storage dramatically reduces glass membrane degradation and extends the functional life of your pH electrode.
• Simple to use - Add a few drops to the electrode's protective cap before capping - no mixing or preparation required.
• Compatible with Hanna pH 7 buffer as an alternative - HI 70300 or pH 7 buffer solution can both be used for short-term electrode storage.

Who Should Use This

All users of Hanna pH electrodes and probes who want to maintain measurement accuracy and extend electrode service life. An essential part of any proper pH electrode maintenance routine.

Compatibility

Designed for use with Hanna pH glass electrodes and probes. Compatible with the protective storage caps supplied with Hanna electrodes. Use HI 70300 or Hanna pH 7 buffer solution for electrode storage.

Frequently Asked Questions

How do I use the electrode storage solution?

Add a few drops of HI 70300 to the protective cap of your pH electrode before capping for storage. This keeps the glass bulb and junction moist until the next use.

Can I use pH 7 buffer solution instead?

Yes - Hanna recommends storing electrodes with either HI 70300 storage solution or pH 7 buffer solution in the protective cap.

What happens if I store my electrode dry?

Dry storage dehydrates the glass membrane and junction, leading to slower response times, inaccurate readings, and accelerated electrode aging.

How often should I change the solution in the storage cap?

Replace the solution in the cap when it becomes discolored or depleted - typically every few weeks under regular use conditions.
