GENERAL DESCRIPTION
An automatic distillation unit designed for distillation of wines, spirits and beers for determination of
alcohol content.
The measured quantity of sample, (100 or 200 ml for alcohol content), is placed in the distillation
chamber, together with the reagents. Reagents are added to neutralise the sample and to make a
conductive solution.
The distillate is collected in a volumetric flask mounted on a precision balance arm. The balance will stop
the distillation when a preset volume has been collected.
The SUPER DEE can be used for determination of other analytical parameters of the wines (e.g. sorbic
acid, total sulphur dioxide). For further informations see the book
“Analysis methods of wines and
alcoholic beverages”
Gibertini – current Edition.
The SUPER DEE has an ecologic device for the waste water : the water passes through the cooling coil
only during the distillation, and it cleans the drainage basin.
The SUPER DEE complies with the directives 2006/42 EEC and 85/375/EEC for the safety of the
analysts. The instruments are also in accordance with the directive 2004/108 EEC (electromagnetic
compatibility).

COMPARISON WITH THE OFFICIAL METHODS
The instruments are in conformity with OIV methods as prescribed by Regulation n. 606/2009 EEC, both
for the Alcoholic Strength by Volume (ASV) and for volatile acidity.
2.3.1 Alcoholic strength by volume (ASV)
For the wines, the current regulations permit the use of any model of apparatus for distillation or
extraction with a steam current on condition that it satisfies the following test:
Distil 5 times in succession a 10 % vol water-alcohol mixture. After the last distillation, the
distillate should present an Alcoholic Strength by Volume of almost 9,9 % vol. In other words,
during each distillation, the instrument does not lose a quantity of alcohol higher than 0,02 %
vol.
For spirits, the following test must be satisfied:
Distil 200 ml of water-alcohol solution, with well-known tritre near 50 % vol. The instrument does
not lose a quantity of alcohol higher than 0,1 % vol.
