GENERAL TIPS FOR AN ACCURATE MEASUREMENT
The instructions listed below should be carefully followed during testing to ensure
best accuracy.
• For dosing the wine sample and the reagent, we
recommend to use the supplied Milwaukee
automatic pipettes
Mi0026
(200
P
L)
and
Mi0024
(1000
P
L).
For a correct use of the Milwaukee automatic
pipettes, please follow the related Instruction Sheet.
• All the reaction times reported in this manual are referred to 20°C (68°F). As a
general rule of thumb, they should be doubled at 10°C (50°F) and halved at 30°C
(86°F).
USING VIALS
• Never insert hot vials into the instrument, or the cuvet holder may be damaged.
• In order to avoid reagent leaking and to obtain
most accurate results, it is recommended to
close the vial tightly with the supplied cap after
addition of reagents or sample.
• Whenever the cuvet is placed into the
measurement cell, it must be dry outside, and
completely free of fingerprints, oil or dirt. Wipe
it thoroughly with
Mi0004
(tissue for wiping
cuvets, see chapter ACCESSORIES) or a lint-
free cloth prior to insertion.
