Performing the density determination of liquids

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 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 balance.
For the density determination of liquids use the high glass beaker (7) and the optional sinker (13).
Density determination kit for Excellence XP/XS precision balances
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
platform, bracket, and pan) as described in Section 2.
Place the empty high beaker (7) on the pan and suspend the
thermometer supplied (11) from the edge of the beaker.
