Analytical balance

Meaning in chemistry, with examples

nounCommon term

In chemistry, analytical balance means: A very sensitive electronic scale, usually reading to 0.1 mg, kept inside a glass draft shield so that air currents do not disturb the reading.

In Turkish: analitik terazi, hassas terazi

How it is used

Used to weigh samples and standards accurately. You tare or zero the balance, weigh by difference, close the doors and wait for the reading to settle. In English you 'weigh' a sample; the 'balance' is the instrument.

Example sentences

  1. Weigh about 0.2 g of the standard accurately on the analytical balance.

  2. Close the doors of the analytical balance before you note the mass.

Common collocations

  • tare the balance
  • weigh by difference
  • top-pan balance
  • four-place balance
  • standard solutionA solution whose concentration is known accurately. It is used to find the concentration of other solutions in titrations or to build calibration curves.
  • volumetric flaskA pear-shaped flask with a long narrow neck and a single line marked on it. Filled to that line, it holds one exact volume, so it is used to prepare standard solutions.
  • molar massThe mass of one mole of a substance, usually given in grams per mole (g/mol). For water it is about 18.02 g/mol.
