Some require acidic soil and other more alkaline. I had some old calibration buffers in plastic containers ... but since they were old and the plastic doesn't prevent water loss and changes in concentrations I couldn't use them. I made up new buffers from the packets and was able to calibrate my pH meter. It was a lot cheaper than buying several different 500 ml of buffer solution. I store the new buffer solution in GLASS containers. Since the remaining packets are dry powder, I don't have to worry about adverse changes that might occur in solutions held for years. ### ⭐⭐⭐⭐⭐ Worked as it should *by T***S on July 26, 2019* Allowed easy calibration of my ph meter. Don't forget to save the solution for future use. ### ⭐⭐⭐⭐⭐ Excellent! *by J***O on July 17, 2016* Excellent products. They all worked as advertised. No problems whatsoever. When I haven't used my pH meter for several months, it has to be re-calibrated with these buffer solutions. I keep the solutions in air tight containers and they last a long time. --- ## 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.pe/products/71738310-digital-aid-ph-calibration-solution-powder-4-00ph-6-86ph](https://www.desertcart.pe/products/71738310-digital-aid-ph-calibration-solution-powder-4-00ph-6-86ph) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-04-24*
