10.2 Density determination (Hydrostatic weighing)
Density is the relationship of weight [g] : volume [cm
3
]. The weight is determined by
weighing the sample in air. The volume results from the ascending force [g] of the
sample dipped in a liquid. The density [g/cm
3
] of that liquid is known (principle of
Archimedes).
The density is determined with help of the underfloor weighing device.
10.2.1 Density determination of solids
Prepare the balance as follows:
Switch off the balance
Remove the weighing pan and carefully turn over the weighing balance.
Screw-in hook for underfloor weighing (option)
Place weighing balance over an opening
Hook-in the sample support
Fill measuring liquid in a vessel e.g. beaker) and temper it.
