An analytical balance is a highly precise laboratory instrument used to measure the mass or weight of samples with high accuracy and precision. It is commonly used in analytical chemistry, pharmaceuticals, and other scientific fields where precise measurements are required. Analytical balances typically have a readability of 0.1 milligrams (0.0001 grams) or less and are designed to minimize external factors that may affect the measurement, such as air currents and temperature fluctuations. They often use a draft shield to protect the sample from external influences and have a built-in calibration system to ensure accurate readings. Analytical balances can be operated manually or electronically, and some models are equipped with advanced features such as automatic calibration, data storage, and connectivity to a computer or other devices.
