Analytical balances are a type of laboratory balance that are used to accurately measure the mass and ratio of chemical and pharmaceutical substances in small quantities. These scales are very sensitive and can measure masses with an accuracy of 0.0001 gram (0.1 mg).

Analytical balances are commonly used in laboratories to measure chemical substances such as drugs, chemicals, food testing materials, and environmental pollutants. They are an important tool in various industries, such as pharmaceuticals, chemical industry, medicine, research and development.

Analytical balances are sensitive to temperature, humidity, vibration and static electricity, and therefore must be used under special conditions often found in laboratories, including stable temperature, relative humidity and protection against vibration.

There are several types of analytical balances, including electromagnetic, electrostatic, and electrochemical balances. Electromagnetic scales use magnetic forces to measure mass, while electrostatic scales use electrostatic forces. Electrochemical balances use electrochemical reactions to measure the mass of substances. Analytical balances are a key tool in many laboratory procedures and significantly affect the quality and reliability of research and production.
