5.3.3 Determine density of sinking solid bodies (d >1 g/cm
3
)
1. Remove the immersion basket and place the glass beaker filled with the auxiliary
liquid in the centre of the platform. Filling height should be approx. ¾ of the
capacity. Make sure that it has no contact with the frame.
Remount the immersion basket. Make sure that it does not touch the glass
beaker. Set balance to zero.
Press the
UNIT key repeatedly, until the balance is in mode of density
determination of solid material.
2. Place sample of solid material in the upper sample dish, see fig. 1, chap. 5.1.2.
The weight of the „sample in air“ is displayed.
3. Wait for stability display ( ), then press the CAL key.
4. Place sample of solid material in the lower sifting bowl, see fig. 2, chap. 5.1.2..
For this remove the immersion basket out from the frame. Always ensure that,
when re-immersing into the liquid, no additional bubbles adhere; it is better to use
pincers or alike to place the sample directly on the sifting bowl. Make sure that the
sample is at least 1 cm immersed.
The weighing balance will first determine then display the sample’s density.
5. If you connect an optional printer you can print the result.
6. Remove the sample. To carry out further measuring, press the CAL -key and start
with step 2.
To avoid corrosion, don't leave the density set immersed in liquid for a long time.
