Analytical Balance
An Analytical Balance is a highly precise measuring tool used in laboratories to weigh very small amounts of materials with extreme accuracy. Think of it as a super-precise digital scale that can measure things as light as a grain of salt. Laboratory technicians and scientists use these instruments daily for tasks like preparing samples, conducting quality control tests, and doing research. Other names for this equipment include "precision balance" or "laboratory balance." Understanding this term is important because it shows that a candidate has experience working with sensitive laboratory equipment and following exact measurement procedures.
