For the density determination of solids, use the low glass beaker (4) and one of the two holders for
solids which sink (6) or float (7).
Density determination kit for Excellence XP/XS analytical balances
Prepare the balance for the density determination (install draft
shield element, bracket, equalizing washer and platform) as
described in Section 2.
Suspend the supplied thermometer (8) from the edge of the
low beaker (4). Place the beaker on the pan and fill it with
auxiliary liquid (liquid of known density ρ
water or ethanol). Add enough liquid to ensure that the solid
is covered by at least 1 cm liquid after immersion.
Suspend the suitable holder (6) or (7) for solids which sink
or float from the bracket (the adjacent illustration shows the
holder for solids which sink).
Ensure that no air bubbles adhere to the immersed part of the
holder (remove any air bubbles by moving the holder or by
means of a fine brush).
Close the draft shield doors and tare the balance.
Place the solid in one of the two weighing pans of the bracket
(2). Wait until the weight display of the balance is stable (sta-
bility detector fades) and note the displayed weight A (weight
of sample in air).
Note
When solids with a weight greater than 0 g are weighed
in air, place in the pan at the top of the holder (above 20 g
cornerload errors may appear on one arm in the weighing).
