Performing the density determination

Note: These instructions explain how to work with the density determination kit. They describe the
procedure for performing a density determination manually.
If you need information about operating your XP/XS balance, please refer to the Operating Instructions
which you received with the balance. The Operating Instructions include instructions for working with
the density determination software which is built into the XP/XS balance.
For the density determination of liquids use the high glass beaker (5) and the optional sinker (10).
ρ = Density of liquid
A = Weight of sinker in air
B = Weight of sinker in the liquid
V = Volume of sinker
ρ
= Air density (0.0012 g/cm
L
α = Balance correction factor (0.99985), takes air
buoyancy of the adjustment weight into account
P = Weight of displaced liquid (P = A–B).
Prepare the balance for the density determination (install the
support plate, bracket, and pan) as described in Section 2.
Place the empty high beaker (5) on the pan and suspend the
thermometer supplied (8) from the edge of the beaker.
