Definition of Weighing

What is Weighing?

Analytical balances are accurate and precise instruments to measure weights.

They require a draft-free location on a solid bench that is free of vibrations.

Modern balances have built-in calibration weights to maintain accuracy.

Older balances should be calibrated periodically with a standard weight.

A few weighing tips follow:

  • Do not bump or place objects on the bench after zeroing the balance.
  • Weigh powders on weighing paper or in weighing dishes. Handle objects with tongs, gloves, or weighing paper to prevent fingerprints.
  • Let hot objects cool before weighing.
  • Weigh hygroscopic materials rapidly since they will absorb water during weighing.
  • When making repetitive weighings always use the same procedure.
