• 3 years warranty

6. Features of the analyzer
• System: 4 wavelenghts and 12
incubation cells designed to
heat samples at a temperature
of 37°C
• Measurement: based on the
reading of absorbance
• Photometric range: 0.0-2.3
Abs; (0.0-4.0 Abs) ampl.
• Hardware and Software:
designed and manufactured by
CDR S.r.l.
• Maintenance: not necessary
periodic calibration

10. ISVEA validation
● CdR – WineLab system is validated by ISVEA
● This system doesn't need calibration. It is already
calibrated and well correlated to the official methods

13. Glucose and fructose in wine
CdR-WineLab's advantages
● Determination of assimilable sugars! Pentose sugars are excluded
● You have a detection limit of 0.1 g/L! You can know with high
precision, in the alcohol fermentation, when the sugars are finished,
to avoid any risk of acetic acid.
●
You can do up to 30 analysis/hour.

CdR-WineLab's advantages
● You can check separately the amount of inorganic nitrogen and
organic nitrogen.
●
The test is not affected by proline and hidroxy-proline
interference.
●
You can do up to 30 tests/hour.

18. Users
Thanks to its simplicity and reliability, WineLab can be used by:
User Advantages
•carry out independently the most
important analysis on wine
Small and medium
•affordable analyzer price
wineries
•lower test price compared to
laboratories
•carry out analysis on a small samples
quantity without using expensive and
Big wineries
complicated automatic analysis
systems
•check the most important parameters
Enological consultants during wine production in the wineries
•create a “portable laboratory”

19. The NEXT NEW TEST
TOTAL POLYPHENOL INDEX
● It is available by the beginning of june
● The polyphenol index is a reading of absorbance at 280nm. So you
can do this without using an UV lamp and without quarz cuvettes
● You can use this test in the mixture of wines to control and keep the
right polyphenols level

20. WineColor
• WineColor is a complementar analyzer to do Colour
Intensity and Tonality reading the absorbance at 420,
520, and 620 nm
• You can do these analysis without dilution of the
sample
• You can control and correct the colour of the wine

21. Summarizing....
● WineLab is a rapid simple and reliable system. This analyzer is able
to control each step of the vinification from grapes to wine in bottle
● The winery is autonomous for the analysis and you can have
a result in real time without waiting for the result from external
laboratory
● WineLab gives an enological consultant the opportunity to
work without opening a laboratory
