ENOLOGICAL ANALYSER - QUICK
Completely automatic oenological analyzer be used together with the Gibertini electronic distilling unit DEE and the steam generator VADE
(according to EEC Regulation N. 2676/90) to determine:
On the distillate:
- the gross and correct volatile acidity
- the total sulphur dioxide content
On the wine:
- the total acidity
- the free sulphur dioxide on white, rosé and red wines: these are measured after treatment with SO2 BUBBLE accessory
Advantages
- completely automatic system
- System operates independently of the operator’s subjectivity
- Time saving compared to manual systems
Technical characteristics
Repeatability
- for the volatile acidity: 0.04 g/l
- for the total sulphur dioxide: 6 mg/l
- for the total acidity: 0.07 g/l
- for the free sulphur dioxide: 2 mg/l
Operation
Automatic colorimetric titration: the instrument records the colour changes of the indicators defining the end-point of the titration.
Time of analysis
Distillation or bubble processes not included - indicative values depending on the sample
- Correct volatile acidity: 5-6 minutes
- Gross volatile acidity: 3-4 minutes
- Total sulphur dioxide: 4-5 minutes
- Total acidity and free sulphur dioxide: 2-3 minutes
Working capability
Indicated values have been evaluated as per maximum values established by the EEC legislation on wines.
- Volatile acidity (maximum limit for red wines 1.20 g/l): about 60 analysis
- Total sulphur dioxide (maximum limit for white and rosé wines 210 mg/l): about 30 analysis
