ANALYTICAL BALANCE Meaning and
Definition
-
An analytical balance, also known as a laboratory balance or precision balance, is a highly sensitive measuring instrument used in scientific laboratories to determine the mass of objects with extreme accuracy and precision. It is specifically designed to measure small quantities of substances, usually in the range of a few milligrams to several grams, and is commonly used in pharmaceutical, chemical, and biological research.
The construction of an analytical balance involves a pan or platform where the substance to be weighed is placed, and a beam or electronic sensor system that measures the displacement caused by the substance's mass. The balance uses various mechanisms, such as magnetic damping or air currents, to ensure stability and minimize external influences that could impact the accuracy of the measurement.
To achieve the utmost precision, analytical balances are typically enclosed in a glass casing to protect the apparatus from drafts and other environmental factors that could affect the measurements. They are also equipped with a level and leveling screws to ensure proper setup and alignment.
The accuracy of an analytical balance is determined by its readability or smallest increment of measurement, which can range from micrograms to milligrams, depending on the model. Most modern analytical balances have a digital display that shows the weight value, and some can even be connected to computers for data logging and analysis purposes.
Overall, analytical balances are indispensable tools in scientific research and quality control, enabling researchers to obtain accurate and reproducible measurements for experiments, formulations, and quality assurance procedures.

Etymology of ANALYTICAL BALANCE
The word "analytical" comes from the Greek word "analytikos", which means "able to analyze" or "dissolving". The term "balance" has Latin roots, deriving from the word "bilanx" (bi, meaning "two" and lanx, meaning "dish" or "scale"). Thus, the etymology of "analytical balance" reflects the combination of these two terms, referring to a weighing instrument that is capable of precise analysis or measurement by utilizing a system of two dishes or pans on a scale.
