Analytical Weighing Balance

An analytical weighing balance is an instrument used to measure mass to a precise degree of accuracy. Often used in laboratory settings, this industrial balance consists of a rigid beam horizontally suspended by a friction support at its center, with weighing pans or scales hung at each end. One of the pans contains an unknown or undetermined weight while the other pan contains weight that is increased by known amounts until the beam becomes motionless or level. Weighing pans are located inside a transparent acrylic-type enclosure equipped with doors to prevent the collection of dust or air currents that can affect accuracy of the measurement. The use of the safety enclosure, which is designed with acrylic airfoils, allows a smooth airflow that prevents fluctuations in the balance or loss of the materials being measured. A slight change in airflow can cause fluctuations in balance, resulting in a compromised final result. Analytical weighing balances are designed with sophisticated electronic technology to allow for accurate weighing of small and lightweight materials. Traditional weighing devices measure weight of objects, while weighing balances measure the gravitational mass of an object.

Analytical weighing balances are used to determine the mass of an object, usually in powdered or crystallized form, to an extremely high degree of accuracy and precision. Extremely small substances are normally placed in a container or on a sheet of weighing foil or paper. The weight of the container or weighing paper must be subtracted in order to obtain exact measurements. Analytical weighing balances must be used in draft-free environments, as the measurements can be influenced by changes in outdoor temperatures, barometric pressure, gravity and humidity. Modern analytical balances are equipped with electronic calibration systems in order to prevent human error and provide consistently accurate results. Modern analytical weighing balances are equipped with high-contrast electronic keypads, display panels and parts-counting features. Measurements can be calculated in several weight modes, including milligrams, kilograms, ounces, pounds, grains, troy ounces, pennyweight and carats.

Analytical weighing balances, with innovated technology and sensitivity, are widely used in industrial and commercial applications, as well as in laboratory and research facilities. These balances are efficient instruments for use in pharmaceutical companies, universities, forensic laboratories, hospitals and scientific research laboratories. Analytical weighing balances are routinely used in chemical laboratories as they are designed to withstand abrasive and hazardous chemicals and solvents, such as ethanol and acetone. The extremely sensitive nature of analytical balances can detect the mass of a single grain of a chemical substance, vital in developing and testing medical compounds. Additional applications include environmental analysis, such as soil, rock and sand testing. Mining companies and metallurgy firms use analytical weighing balances to determine accurate and exact measurements, usually calculated in carat weight. Jewelry manufactures can ascertain gemstone clarity and carat weight with exactitude.

Forensic laboratories rely on analytical weighing balances to assist in evidence collection, analysis of bodily fluids, tissues and substances in determining causes of death. Numerous scientific disciplines, including pathological laboratories and hospitals use weighing balances for diagnostic purposes and biological material testing in determining the causes and extent of suspected diseases. Analytical weighing balances are effective devices used for industrial, agricultural, environmental and energy analysis.
