For the Determination of Titratable Total Acidity in Wine
Acids occur naturally during the growing process of grapes and as a
part of the fermentation process. In proper proportion, acids are a
desirable trait and give the wine character.
Total acidity
(titratable acidity) is the sum of the fixed and volatile acids. In the
U.S., total acidity is expressed in terms of tartaric acid.
Tartaric acid directly affects the color and flavor of wine and,
depending on the wine, is sought in a perfect balance of sweet and
bitter components. Too much acidity makes wine tart and sharp; too
little makes it flat and uninteresting. Proper acidity in wine is what
makes it refreshing and an ideal accompaniment to food.
· Microprocessor-based automatic titrator specially designed for the determination of total acidity measurements in wine analysis
· Titrator, magnetic stirrer, electrode holder and reagent holder in 1 compact unit
· Pre-programmed analysis method for wine samples; results are displayed in g/L as tartaric acid
· Simple to operate - results in minutes
· High accuracy piston driven dosing system
· Automatic stirrer speed control – maintains consistent stirring speed at approximately 600 rpm regardless of viscosity of solution
· Real time graphing with exportable data
· Log on demand – log data on up to 200 samples
· GLP feature, to view calibration data for titrator and pump
· Can also be used as a pH/mV meter
