5 Density determination of solids
For the determination of the density of solids, the solid is first weighed in air and then
in the aid liquid, whose density is known. From the weight difference results the
buoyancy from where the software calculates the density.
As aid liquid, usually distilled water or ethanol is used, see density table chapter 8.
Prepare balance as described in chapter 3 "Installation of density determination set".
 Place the retainer of the immersion basket on the cone of the weighing plate.
 Place the platform for glass containers in a way that it does not touch the
retainer of the immersion basket.
 Place beaker in the centre of the platform Make sure that it has no contact with
the retainer or with the immersion basket.
 Hang the immersion basket on the retainer. Make sure that it is centred in the
recess.
 Fill the aid liquid into a glass beaker. Fill in so much liquid that the solid matter
after immersion remains at least 1 cm under the liquid level. Immerse
thermometer
 Bring aid liquid / instruments / sample to the right temperature until you
achieve a constant temperature. Observe the warm-up time of the balance.
 Connect balance to power supply, the balance will carry out a self-test. Switch
on using the ON/OFF button and wait until the gram display appears.
