How is CDR WineLab® System composed?

Instruments

CDR WineLab® Analysis System uses an analyzer based on photometric technology, available in two versions, and a dedicated kit of pipettes.

The ease and reliability of the system is based on exclusive technical features:

CDR WineLab® is the all-inclusive intuitive system to perform chemical analyses for qualitycontrol of eggs and egg products.

  • reading cells are equipped with state-of-the-art LED emitters;
  • reading and incubation cells are thermostated at 37 ° C;
  • the analyzer is supplied pre-calibrated, no further calibration or maintenance is required;
  • instruments can be equipped with a printer or PC connection.

Reagent Kits

CDR WineLab® Analysis Systems use low toxicity disposable pre-vialed reagents, specifically developed by the research laboratories of CDR.

The use of pre-vialed reagents and dedicated analytical procedures allows:

CDR FoodLab® Analysis Systems use disposable pre-vialed reagents specifically developed by the research laboratories of CDR.

  • 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;
  • removing all needs to handle toxic or carcinogenic agents;
  • making the amount of chemical waste generated only a fraction of the waste generated by standard methods.

Reagents come in packages containing 10 test tubes each, to perform 10 tests (or packages for 100 tests containing 10 single packages of 10 test tubes each).

Save your time

CDR WineLab®  allow performing several analyses at the same time on the same sample or sixteen different assays for the same parameter on a batch of different samples.

Furthermore, CDR WineLab® Multitasking Mode allows to manage the determination of several analytical parameters at the same time, even on different wine samples.

For example, the Multitasking Mode enables to quickly determine the complete analytical profile of a wine. In a single testing session, in just 10 minutes, CDR WineLab® can determine:

  • Acetic acid
  • L-malic acid
  • L-Lactic acid
  • Sugars
  • pH
  • Total acidity
  • Free SO2
  • Total SO2
  • Alcohol by volume

The Multitasking Mode allows the system to process one analysis and to start another one at the same time, with the possibility to go back to the first one at any moment.

Validation and Studies

CDR WineLab® validation by an important reference laboratory

CDR WineLab® wine analysis system has been compared with the reference methods 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.

Features of Analytical Methods

Wine is analyzed as it is, while must just requires an easy and rapid preparation developed by CDR.

Analytical procedures and dedicated pre-vialed reagents specifically developed by the research laboratories of CDR allow:

  • making analytical procedures extremely fast and easy;
  • not to get in touch with toxic or carcinogenic compounds;
  • to avoid using extractor hoods;
  • not to wash either containers or traditional glassware.

CDR WineLab® Reduces Waste Costs: the amount of chemical waste generated is only a fraction of the waste generated by standard methods.
