Answer:

  • using subtraction to determine the volume dispensed.
  • making sure that you read the volume with the liquid inside the pipette at eye level.
  • ensuring that air bubbles are not in the column of liquid inside the pipette.

Explanation:

The pipette is a widely used laboratory material, and its main function is to transport precise quantities of liquid material. They are used, for example, in various medical examinations and in the study of molecular biology. There are several types, such as the graduated pipette, the volumetric pipette, the automatic pipette and also the micropipettes (for very small amounts of liquid). Using a pipette requires careful attention not to use wrong volumes of liquid to be used. For this reason, it is correct to say that when handling a pipette we must:

  • using subtraction to determine the volume dispensed.
  • making sure that you read the volume with the liquid inside the pipette at eye level.
  • ensuring that air bubbles are not in the column of liquid inside the pipette.
