I use this to balance the number to where I want. ofcourse youll want to be in the lower ranges but they work great. Containers are well built and dont leak. I checked the pH with some strips and the levels were bang on. I thought for the price it was worth it. ### ⭐⭐⭐⭐⭐ Good Product *by J***B on 19 January 2026* Seems to work well ### ⭐⭐⭐⭐⭐ Good value for pH references *by T***P on 10 October 2025* These are the go-to reference solutions for testing the acid levels in wine. This brand has a 2-year expiration date. The coloration of these references makes it easy to not mix them up. ## Frequently Bought Together - Apera Instruments AI1113 pH Calibration Buffer Solution Kit (7.00, 4.00), 8 oz.
