Lab mechanical balances are precision weighing instruments used in scientific research, quality control, and educational settings. They are designed for measuring small to medium-sized samples with high accuracy and reliability. These balances use a system of levers and counterweights to balance the weight of the sample against a known standard, allowing for precise measurements of mass. They are commonly used in chemistry, biology, physics, and other fields where accurate measurements are critical. Lab mechanical balances are available in a range of models with varying capacities and sensitivities to suit different applications.
