Lab weighing density determination in plastics
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.

Topic world Weighing
Precise weighing is critical in laboratory and industrial environments. From accurate dosing of chemicals for research experiments to mass production of products, precise weight determination is often the first and most critical step. Modern balances and weighing instruments are sophisticated, offer impressive precision and are resilient to external influences such as temperature and humidity.
