The calibration curve of CDR WineLab for determination of pH in wine, obtained using reference methods, confirms the excellent linearity of the system over the whole testing range.
Composition of the Kit and Reagents
Code *300310: The kit, designed for 10 tests, comprises:
1) R1: pre-filled cuvettes with reagent.
pH measures the dissociation grade of acids present in wine. This parameter influences the vinification and conservation of wine. The range of pH value is approximately 3.00 – 4.00. There is not any legal limit.
pH is determined through acid-base colorimetric reaction in which a phenol derivative, for addition of wine, undergoes a decoloration. The entity of this decoloration, measured at 630nm, is correlated to pH in the sample.
