Micropipettes are routinely used in biology and chemistry labs to transfer small volumes of liquids. Other instruments can also be used to measure liquids in the lab, but the micropipette is best to transfer very small quantities such as .001 mL (one microliter or 1 L.) You will save time and energy as well as gain confidence by completing the exercises that follow before you come into lab.
