The density kit is used together with a balance. A glass body of defined volume is weighed in air (M1), dipped into the sample and weighed again in the sample (M2). The difference between M1 and M2 (buoyancy) divided by the volume of the glass body is the density of the sample. A special holder can also be used to measure density of solids, using a reference liquid (water, ethanol or user defined).

Advantages:	Disadvantages:	Main applications:
no manual reading	long and difficult thermostating	density of solids
GLP printout	large sample volume required	density of porous materials
just an accessory to a balance, therefore relatively inexpensive		density of viscous material (using a gamma sphere)
