Density balances / Balances for density
Density balances determine the density in liquid and solid materials according to the lift gain theory l. Density balances are mainly electronic and very accurate. Density balances are very useful to know the density in plastics, rubbers, frit metals, ceramic, glasses as well as other non-metallic materials. The way to determine the density is highlighted by the high accuracy and the fast taking of weight results. Density in liquids is measured in relation to the lift gain theory with a glass element. On the other hand, the density in solid materials is obtained with the weight and volume of a sample. The weighing unit in density balances determines the weight. The volume is obtained in relation to the pressure of the sample when it is introduced in a liquid, so the density of that liquid must be previously known.

An easy process to calculate the density at laboratory consists on determining the mass and volume of an element and then making the calculation according to the density formula: density [kg/m³] is equal to the mass [kg] divided by the volume. Volume in liquids is measured according to the usual procedures to determine volume. The use of flasks, cylinders and Pasteur tubes will be necessary for determining volume in liquids. Regarding solid materials the case of solid materials volume can be calculated in relation to their shape, as in the case of cubes. With more complex formulae you have the option of introducing the object inside a cylinder filled with water. The increase in the level of water will determine the real volume of the object.

Density calculation with hydrostatic balances
According to Archimedes Principle an object completely immersed in a fluid (liquid or gas) displaces a volume of fluid exactly equal to the volume of the object. The weight of that volume of displaced fluid is the buoyant force acting on the object. Besides, the principle states that the buoyant force acting on an object placed in a fluid is equal to the weight of the fluid displaced by the object.
