Measuring Density with Laboratory Balance
Use Your Balance and a Density Kit to Determine the Density of Solid, Liquid and Viscous Substances
Measuring density of a sample is an important quality parameter of both raw materials and finished products. Various techniques enable the density of solid, viscous and liquid materials to be accurately determined e.g. metals, plastics, chemicals, lubricants and food.
Density for Quality Control
A variation in a raw material, indicated by a change in the density, may have a detrimental outcome on the functioning or quality of the final product. Density measurement of raw materials can be used to confirm the purity of the material. If a substance has been adulterated with a cheaper alternative, the measured density of the composite material will be different from the pure substance.
