The “Density” application
120
After you have tared the sample you are prompted to immerse the gamma sphere in the
sample substance.
The weight of the substance which is displaced by the gamma sphere is displayed in the
bottom left corner of the window.
Press “OK” to accept the weight value.
The balance now determines the density of the pasty substance and displays the result.
Either the compensated result, the uncompensated result, or both is/are displayed depend-
ing on the settings you made for the result display (see section 10.3.5).
If a printer is connected, you can press the «F» key to print out a report of the density
determination result according to your specifications (section 10.3.8). The result is saved
until the next density determination using the same method has been completed, so it
can be printed out again if required.
10.4.4 Determining the density of liquids using a pycnometer
A pycnometer – a glass container with a known capacity and net weight – is often used for determining the density of liquids. The liquid
is poured into the pycnometer and weighed.
In the application-specific settings, select “Pycnometer” as your method (section
10.3.2).
Activate the appropriate function keys and information fields (sections 10.3.6 and
10.3.7). The example shown here illustrates practical settings for determining the density
of liquids using a pycnometer. Note: The “Temp. AL” function key in the example shown
here, and the information field with the same name are not required for this method of
density determination. You can, nevertheless, use these function keys to enter the current
ambient temperature. This will in turn also be included on the printouts, and indicates the
temperature at which the density was determined.
Press the “Wgt. Pycno” function key and enter the weight of the pycnometer (in this
example, 43.83 g).
Press the “Vol. Pycno” function key and enter the volume of the pycnometer (in this
example, 50.331 cm³).
Press the “Start”, function key to start the density determination. You will then be prompted
to place the filled pycnometer (the selected weight of the pycnometer appears in the lower
left-hand corner of the window with a minus sign).
Place the filled pycnometer on the pan. The net weight of the sample appears in the lower
left-hand corner of the window. Press “OK” to accept the weight value.
