System overview WineLab system is constituted by:• A thermostated analyzer based on photometric technology which uses solid-state emitters• Kits with pre-filled cuvettes and reagents, developed by our research laboratory, ready to use• Pipettes• Print Manager, a software which enables to connect the analyzer to the PC• Users manual• Illustrated data sheets• 3 years warranty
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

Glucose and fructose in wine CdR-WineLabs 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.
Free sulfur dioxideStep 1: taking and incubation of the sample
Free sulfur dioxideStep 2: addition of the R2 and reading of the sample

Yeast Assimilable Nitrogen CdR-WineLabs 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.
UsersThanks 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 parametersEnological consultants during wine production in the wineries •create a “portable laboratory”
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
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
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
