The second time we used the solution, there were black globes of mold growing in it. The standard was wildly off when we attempted to use it (silly to try this) and the solution was within the use date (hadn't expired yet). We stored the solution according to the label and we handled the calibration solution using gloves and on a clean surface. I have used many conductivity solutions and have never had this issue. Maybe it was just a one off, but I will be using a different conductivity solution from here on out. We can't afford to use poor quality calibration solutions to calibrate thousand $$ instruments while in remote places ## Frequently Bought Together - Oakton AO-00653-18 Oakton Conductivity and TDS Standard, 1413 Μs; 500 mL - Oakton AO-00606-10 Oakton Conductivity and TDS Standard, 12,880 Μs; 500 mL - Oakton AO-00653-16 Oakton Conductivity and TDS Standard, 84 Μs; 500 mL --- ## 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.jp/products/40520537-oakton-ao-00653-18-oakton-conductivity-and-tds-standard-1413](https://www.desertcart.jp/products/40520537-oakton-ao-00653-18-oakton-conductivity-and-tds-standard-1413) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-24*
