How To Use a Precision Balance Scale

how to use a balance scale

There are several types of scales and balances for different needs. A precision balance scale is used for exact mass measurement. Its accuracy is not affected by gravity, unlike spring scales. One such precision scale is the analytical balance or a chemical balance, which is a high-precision beam balance used in quantitative chemical analysis.

Pocket scales are small portable scales used by jewelers and chemists to weigh fine items and powders in circumstances where a laboratory scale is not available.

Gram scales measure the weight of an item in grams instead of ounces, pounds or kilos. A beam balance is composed of a level with two equal arms and a pan suspended from each arm while an ordinary balance is a scale for weighing that is affected by gravitational pull.

An analytical balance is very sensitive. It can measure the mass of a single grain of substance. It should be used in a draft-free environment and placed on a solid bench or table that is free of vibrations.

When you need exact weight measurements, then you need a precision balance scale. Let us see the steps in using a precision balance scale in a laboratory setting.

  1. Before you weigh anything on an analytical balance, it has to be tared or recalibrated to read 0.0000 g. Press and release the Tare button to recalibrate.
  2. Make sure that you do not bump the balance once you have done your recalibration.
  3. Chemicals and other substances to be weighed should be placed on paper or dishes.
