Hanna GroLine Storage Solution – 500 mL (HI70300-023) | For pH & ORP Electrodes
Extend the life and accuracy of your pH and ORP electrodes with the Hanna GroLine Storage Solution (HI70300-023). Specially formulated with reagent-grade chemicals, this 500 mL electrode storage solution is designed to keep your pH and ORP probes in optimal condition when not in use.
Unlike distilled or deionized water—which can damage the sensitive glass membrane and shorten sensor life—GroLine Storage Solution maintains hydration of the glass sensor and keeps the reference junction clear. Its unique formula also helps prevent microbial growth and minimize osmotic/diffusion effects, protecting the internal electrolyte and ensuring consistent, fast readings.
Key Features:
- Maintains Electrode Performance: Keeps pH and ORP electrodes properly hydrated
- Promotes Fast, Reliable Readings: Prevents drying and junction clogging
- Microbial-Resistant Formula: Minimizes contamination and osmotic effects
- Easy to Use: Ideal for long-term storage or post-cleaning rehydration
- Secure Packaging: Airtight seal, lot number, and expiration date for quality assurance
Best Practices:
- Never store electrodes in distilled or deionized water—this damages the sensor
- After cleaning with a pH electrode cleaning solution, soak in HI70300-023 for at least 1 hour before taking measurements
- Store electrodes by filling the cap with storage solution or placing the probe in a clean container filled with HI70300-023
