Sartorius la series Operating Instructions Manual page 74

Practical Example
Displacement: Determine the Density of Samples of a Solid Using the Displacement Method.
Reference Liquid: Ethylene glycol. Temperature: 23°C (73.4 °F). Set the density at 20°C (68°F) to 1.113 g/cm
the volume expansion coefficient at 20°C (68°F) to 0.00064 grd
Settings (changes in the factory settings required for this example):
Setup: App: Application 1: Density: Method: Displacement
Setup: App: Application 1: Density: Liquid for buoyancy: User-definable
Step
1. Delete previously stored values
if necessary
2. Change configurations:
Temperature: 23.0
Density of ref. liquid: 1.113
Expansion coefficient: 0.000640
3. Place the container with the
reference liquid on the balance
4. Tare the balance
5. Determine the weight of the
sample in air: place sample
on the weighing pan
6. Store weight value
7. Determine the weight of the
sample in liquid: place sample
in the sample holder
8. Store weight
Density of sample is displayed
