Cleaning the pipet
Prepare a solution of soapy water in a beaker. Draw the solution
into the pipet, and wet the walls. Do not get the mouth of the
pipet wet! Drain the wash water.
Put distilled water into another beaker. Draw distilled water
into the pipet and rinse out the soapy water. Rinse several times
to remove all soap residue.
DO NOT attempt to fill the pipet by running water from the
tap directly into the mouth of the pipet.
