General information about our pH buffers / calibration:
Available grades:
Technical Quality
The buffer solutions of HANNA instruments include solutions from pH 1.00 to pH 13.00 and allow calibration over the entire pH scale with an accuracy of ± 0.01 pH. The buffer solution series is particularly suitable for pH measurements that require high accuracy. All solutions with certificate of analysis.
Millesimal Quality
Accuracy of ± 0.002 pH for calibration of measuring instruments with 0.001 resolution. All solutions in opaque packaging with certificate of analysis.
Standard Quality
Accuracy of ± 0.01 pH in different packaging, with or without a certificate of analysis.
Available packages: Bottle: 230ml – 500ml – 1L Can: 3.78 L (gal) Individual portions – and virtually always fresh & no contamination risk Shelf life up to 5 years
