analytical balance

An analytical balance is a highly precise instrument used primarily for quantitative chemical analysis. It is a type of balance, a measuring instrument designed to compare the weights of two bodies to determine their mass difference.12

While the exact origin of the equal-arm balance dates back to ancient Egypt, the development of modern mechanical balances was significantly advanced by the invention of knife-edges in the 18th century. By the late 19th century, balances had become some of the most precise measuring devices globally. In the 20th century, electronic balances emerged, utilizing electrical compensation instead of mechanical deflection for measurement.2

Balances are fundamental in various laboratory measurements, including density determination, which involves measuring the ratio of mass to volume.3
