Ideal for professionals who demand reliable calibration and probe longevity, this solution supports optimal electrode performance with traceable quality assurance. ## Description pH/ORP electrode storage solution. To minimize clogging and ensure fast response time, always keep the glass bulb and the junction of your pH electrode moist. Store the electrode with a few drops of HI70300 storage solution in the protective cap. Size: 500ml. Pack of 1. Review: Overall quality beyond doubts—well worth adding to your calibration routine! - Keeps the glass membrane hydrated, prevents microbial growth, and protects the reference junction—crucial for fast and accurate readings. I use it after cleaning or during idle periods; soaking for an hour reactivates sluggish probes reliably. The bottle is sealed with expiration and lot info for traceability Review: Nice - Works great. I use this to store my electrode in between uses because the electrode is to never go dry. If you don't use the electrode for a long time and let it dry out, soak it in this solution for about an hour or more, then calibrate. No biggie. It will mold and grow bacteria in solution after awhile. I've found that rinsing the electrode in between uses helps keep this to a minimum. ## Features - pH/ORP electrode storage solution - To minimize clogging and ensure fast response time, always keep the glass bulb and the junction of your pH electrode moist - Store the electrode with a few drops of HI70300 storage solution in the protective cap - Size: 500ml - Pack of 1 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01J5F1U3G | | Best Sellers Rank | #63,937 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #10 in Electrolyte Solutions | | Date First Available | January 7, 2008 | | Department | mens | | Is Discontinued By Manufacturer | No | | Item Weight | 1.1 pounds | | Item model number | HI 70300L | | Manufacturer | Hanna Instruments | | Product Dimensions | 50 x 50 x 50 inches | ## Images ![Hanna Instruments HI70300L pH/ORP Electrode Storage Solution, 500mL Bottle - Image 1](https://m.media-amazon.com/images/I/61wTUyxGBBL.jpg) ## Questions & Answers **Q: whats the difference between this and their GroLine storage solution?** A: I use Skunk Labs Potassium Chloride solution . it's cheaper **Q: After a few days, the solution becomes crystallized and chunky. What am I doing wrong?** A: Not sure. Mine lasted for weeks and only became crystallized of left uncapped or in the open air . Cld be bad to begin with if only a cpl days . Try gettin a refund or a new order and see what happens .. **Q: How much of this are we supposed to use on the ORP meter tip? Just pour some into the basin that the tip slides into?** A: Well Hanna says not to store the unit in that cap for what reason idk at least on my ph 55 meter but I use those packets it comes with to store it in and use just enuff to cover the electrode then change it once a week or so not sure what ph meter u have but you could most likely use the cap I used it on the last unit I owned so ur call **Q: This is probably an obvious answer but I thought I'd be careful; Can this storage solution be used for an Oakton pH meter? This is way cheaper.** A: I'm sure its universal just one thing when I used it, it got crusty on me so I just use ph 4 or 7 solution to store mine in and use the cleanin solution once a week on it is all but it would work for your meter if you wanna try it out for yourself and see. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Overall quality beyond doubts—well worth adding to your calibration routine! *by S***L on August 1, 2025* Keeps the glass membrane hydrated, prevents microbial growth, and protects the reference junction—crucial for fast and accurate readings.
