Application
The buffer solution is used as a standard in analytical procedures for the calibration of pH measuring instruments or pH electrodes and as a control for the measurement of pH of other solutions.
It may be used to calibrate a pH benchtop meter to study the designing of hydrophobic eutectic mixtures for the extraction of volatile fatty acid extractants (VFAs)

General description
The citric acid/sodium hydroxide/hydrogen chloride certified buffer solution is gravimetrically prepared using high-quality reagents at a registered calibration laboratory. Its pH value of 2.00 at 25 °C is measured using a combined glass electrode following a 5-point calibration method. The measurement is made following DIN 19268 using reference buffer solutions compliant to DIN 19266, NIST, IUPAC, Ph. Eur, and USP. The pH value of the buffer strongly depends on the temperature and therefore a constant temperature must be maintained during its use.
