Gravimetric Buoyancy

VWR Analytical Balance
Mass Range: 10mg - 160g
Precision: 0.1mg (0.0001g)

The MILL has a scale sensitive to +/- 0.0001 grams.  It is useful for determining density by Archimedes method and can be used to take measurements over time.  For example, it could be used to measure the rate at which a liquid evaporates.
