The calibration curve of CDR CiderLab for determination of pH in cider, obtained using reference methods, confirms the excellent linearity of the system over the whole testing range.
Reagent test Kits
The reagents are packaged in foil pouches containing 10 tubes useful to perform 10 analyses.
This is the minimum package that allows the use of CDR systems even to those who need to make a few analyses, thus not wasting reagents.
There are also boxes of 100 tests, however, packaged in 10 bags of 10 tubes containing the reagent.
Code *300310: The kit designed for 10 tests
Code *300305: The kit designed for 100 tests
The reagents have a shelf-life of 6 months.
pH measures the dissociation grade of acids present in cider. This parameter influences the vinification and conservation of cider. 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 cider, undergoes a decoloration. The entity of this decoloration, measured at 630nm, is correlated to pH in the sample.
