The storage solution should work with all meters. I would contact Extech and confirm with them to be 100% certain. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Must have these if you own a pH pen *by A***E on 10 September 2025* ### ⭐⭐⭐⭐⭐ GOOD *by T***. on 10 February 2025* ### ⭐⭐⭐⭐⭐ I trust this company. *by D***. on 16 April 2025* ## Frequently Bought Together - Apera Instruments, LLC-AI1109 8oz. pH Calibration Buffer Solution Kit (pH 4.00, 7.00 & 10.01), plus 4oz 3M KCL Storage Solution for pH/ORP Electrodes - Apera Instruments AI311 Premium Series PH60 Waterproof pH Pocket Tester Kit, Replaceable Probe, ±0.01 pH Accuracy, Lcd display - Apera Instruments 3M KCL Storage Soaking Solution (8 oz.) for pH and ORP Electrodes --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/712551634-apera-instruments-llc-ai1109-8oz-ph-calibration-buffer-solution-kit](https://www.desertcart.in/products/712551634-apera-instruments-llc-ai1109-8oz-ph-calibration-buffer-solution-kit) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-04-23*
