Definition

Noun: A highly precise weighing instrument, specifically a type of beam balance, designed for determining mass with extreme accuracy, typically used in quantitative chemical analysis and other scientific applications requiring exact measurements.

Usage

The term "analytical balance" refers to the specific instrument itself. It is used as a countable noun. * The chemist weighed the sample on an analytical balance. * Proper calibration of the analytical balance is essential for accurate results. * Our laboratory has several analytical balances in the preparation room.

Examples

• To determine the exact concentration, the precipitate was dried and its mass measured using an analytical balance.
• The sensitivity of a modern analytical balance can reach 0.1 milligram.
• Before beginning the titration, ensure the analytical balance is on a level, vibration-free surface.

Advanced Usage

• "to use/tare an analytical balance": Refers to the operation of the instrument, including using the tare function to reset the display to zero with a container in place.
  • Remember to tare the analytical balance with the weighing boat before adding the powder.
• The instrument is often associated with controlled environments to prevent interference from air currents, dust, or static electricity.

Variants and Related Words

• Balance (n): A broader term for any instrument that measures mass. An analytical balance is a specific, high-precision type of balance.
• Microbalance (n): An even more sensitive balance capable of measuring masses smaller than those typically measured by a standard analytical balance.
• Scale (n): A more general term for a weighing device, which may be less precise than an analytical balance (e.g., a kitchen scale).

Synonyms

• Precision balance: A synonym emphasizing the key characteristic of the instrument.
• Laboratory balance: A broader term that can include analytical balances and other balances used in lab settings.

Related Phrases

• Quantitative analysis: The primary field of use for this instrument, where determining exact amounts is crucial.
• Weighing by difference: A common technique used with analytical balances where the mass of a substance is found by weighing the container before and after transferring the substance.
