Application note: Easy density determination for consistent plastics quality

Density determination of solids on an analytical balance is a straightforward quality control test

Density determination is essential for consistent plastic quality. The Archimedes principle states that a body immersed in fluid experiences an apparent loss in weight equal to the weight of the fluid it displaces. This ancient principle, from around 200 BC, is precisely what is used nowadays to determine density gravimetrically. It is what Mettler-Toledo's MS-TS, ML-T and ME-T balances make use of in the modern world to test the completeness of molded plastic parts to ensure consistent product quality. Density determination involves weighing the object to be tested in air and then in a liquid of known density (usually water or ethanol).

This application note describes how the density of solid plastic parts can be easily determined using the integrated application on a MS-TS, ML-T or ME-T analytical balance with a Density Kit.
