Density
Purpose: The density of solids can be determined using the buoyancy method. The density
is determined using Archimedes' Principle. The upward buoyant force exerted on
a body immersed in a fluid is equal to the weight of the fluid the body displaces.
Calculation Basis for Density Determination
Density determination using the buoyancy method is based on the following
formula:
Density of sample (rho)
Density of buoyancy liquid
fl
W Weight of sample in air
a
W Weight of sample in liquid
fl
Buoyancy: = (W / (W

Prerequisites: A Sartorius density determination kit is required for this function:
– for analytical balances YDK03
– for precision balances YDK04.
Mount the density determination kit on the balance and prepare it as described in
the kit instructions.
