Density Determination Of Solids - KERN YDB-04 Operating And Installation Instructions

4 Density determination of solids

For the determination of the density of solids, the sample is first weighed in air and
then in the aid liquid, whose density is known.
The buoyancy results from the weight difference.
In KERN EMB 200-3V the balance calculates automatically the density and displays
it.
For models without density calculation function the density must be calculated
according to the following formula.
ρ
Density of sample
A Weight of the sample in air
B Weight of the sample in the aid liquid
ρ
Density of the aid liquid
o
The air buoyancy is not considered in the formula.
In most cases distilled water or ethanol are used as aid liquid.
Preparation:
 Install density determination set, see chap. 3.1.2
