With CDR CiderLab, device for cider analysis, is possible to determine Total Acidity in cider with a simple photometric reading of a sample of cider as is dispensed in a cuvette that is prepared with the reagent and already provided.
It is not necessary to resort to the tritation that is required from the OIV reference method. The results are correlated with the ones obtained with OIV reference method.
The Analyzers CDR CiderLab for determining Total Acidity in Cider
The system is supplied pre-calibrated and ready for use.
Results are expressed in accordance with the reference method.
The reagents have a shelf-life untill 18 months
The analytical methods are simple: the system does not require an equipped laboratory or skilled staff.

Test type: End Point.
Time testing: one test 1 minute – 80 Test/Hour.
Are possible test sessions with several samples, up to a maximum of 16.
The calibration curve of CDR CiderLab, obtained using reference methods, potentiometric titration, 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 *300320: The kit, designed for 10 tests
Code *300315: The kit, designed for 100 tests
The reagents have a shelf-life of 6 months.
Total acidity in cider is the sum of the titratable acidities; it is determined for addition of an alkaline solution titrated until reaching pH 7. The carbon dioxide is not included in the total acidity.
