LABORATORY BALANCE Meaning and
Definition
-
A laboratory balance refers to a highly accurate and specialized weighing instrument used in scientific research, experimentation, and quality control measures. It is designed to accurately and precisely measure the mass or weight of substances or samples within a laboratory setting.
A laboratory balance typically consists of a weighing pan, on which the sample to be measured is placed, and a load cell or balance mechanism that senses and measures the weight. These balances often employ sensitive sensors and sophisticated technology to ensure accurate and precise measurements.
Laboratory balances are calibrated to function optimally in controlled environments, such as within enclosed laboratory cabinets or chambers, to minimize the effects of external factors like air currents, temperature variations, and moisture, which may interfere with the measurement accuracy. Substances used in the laboratory, such as powders, liquids, or solids, are carefully placed on the balance pan using appropriate handling tools to prevent contamination and ensure accurate readings.
Laboratory balances come in various types and capacities based on the specific measurement requirements. These may include analytical balances, which offer high precision for measurements of small sample sizes, and precision balances, which provide comparably lower precision but higher capacity for larger samples. Many modern laboratory balances also come equipped with additional features like touchscreen displays, built-in calibration functions, and data communication capabilities, facilitating ease of use and data integration with other laboratory equipment and systems.
Etymology of LABORATORY BALANCE
The word "laboratory" comes from the Latin word "laboratorium", which means "a place of labor". It originated from the Latin word "laborare", meaning "to work".
The word "balance" comes from the Latin word "bilanx", which means "double-scaled". It is derived from the combination of "bi-" meaning "two" and "lanx" meaning "dish" or "scale".
Therefore, the term "laboratory balance" refers to an instrument used in a "place of labor" or a laboratory that employs a double-scaled mechanism to measure the weight or mass of substances accurately.
