GENERAL TIPS FOR AN ACCURATE MEASUREMENT
The instructions listed below should be carefully followed during testing to ensure
best accuracy.
• Use the supplied plastic pipette for adding the exact amount
of wine sample (15 mL) or reagents A or B (up to the 20 mL
mark) to the graduated glass vials. The liquid in the vial
forms a convexity on the top; the bottom of this convexity
must be at the same level of the mark.
• To transfer the supernatant organic solvent from the vials to
the cuvets use two different clean 1 mL pipettes, one for the zero and one for the
sample.
a) squeeze the bulb of the pipette;
b) insert the plastic pipette into the supernatant organic solvent and release the
bulb slowly, paying attention not to transfer the wine sample too;
c) fill a cuvet with organic solvent by squeezing the bulb of the pipette.
