CDR WineLab® validation by an important reference laboratory
The CDR WineLab® wine analysis system has been validated by the ISVEA reference laboratory. Comparative assays between the method exploited by the CDR WineLab® analyzer and the reference methods were carried out using sequences of samples made up of different types of wine in order to verify the reliability of the results obtained with the CDR WineLab® system.
Reference methods used for the validation:
Glucose and fructose – HPLC method
Malic acid – HPLC method
Volatile Acidity – Titration after distillation method EEC regulation 2676/1990 17/09/1990 ECC OJ L272 03/10/1990, Exhibit point 14, OIV MA-F-AS313-02-ACIVOL 2006
Total sulphur dioxide – Titration after distillation method EEC regulation 2676/1990 17/09/1990 EEC OJ L272 03/10/1990, Exhibit point 25 par 2.2
The reference institute concluded that the tested CDR WineLab® methods are to be considered substantially valid. In fact, the reference methods are statistically equivalent (95%) to CDR WineLab® methods.
CDR WineLab® for the correct management of alcoholic fermentation
In extreme climatic conditions, in addition to the usual analysis of sugar, total acidity, pH and acetic acid, yeast assimilable nitrogen and gluconic acid are the fundamental parameters available to the oenologist to better manage the fermentative process, an essential starting point to obtain a quality wine.

With the CDR system, you can perform your tests in total autonomy
Neither skilled staff nor a dedicated external laboratory is needed to use our systems. CDR FoodLab® optimizes
traditional testing methods, making them faster and easier, while guaranteeing accuracy standards in line with
the reference methods.
CDR FoodLab® Analysis Systems use disposable pre-vialed reagents specifically developed by the research
laboratories of CDR. The use of pre-vialed reagents and the analytical procedures allow:
a sample preparation that is quick and easy, when needed at all;
making analytical procedures extremely fast and easy;
removing all needs for complex calibration procedures.
Reagents come in aluminum packages containing 10 test tubes each to perform 10 tests (or packages for 100
tests containing 10 single packages of 10 test tubes each).
Just a few steps and results are yielded right away
Just a few steps will suffice to carry out your analysis in a rapid way in total autonomy. The system is composed
of both the analyzer based on photometric technology and a kit of low toxicity, pre-vialed reagents, developed by
CDR FoodLab® is cost-effective because it does not require the use of expensive equipment and does not
entail maintenance, assistance or calibration costs. Find out how it works
