FLOATERS INTERCHANGEABLE IN MASS AND VOLUME
Particular care must be paid in the construction and calibration of floaters.
They are all interchangeable in mass and in volume in order to facilitate utilization; for
example to determine the specific gravity of a must or a given wine and the relative
ASV, 2 separate floaters can be used without problem to avoid contamination
(preliminary check of the compensation factor; see chapter 4.3).
To obtain the above both the suspension

wire and the surface of the glass have been
subject of many studies in order to resolve the problems caused by surface tension,
from the volume of wire and from electrostatic charges.
