Explain how a Pipette is used.

Explain how a Pipette is used.

A pipette is used to measure small amounts of solution very accurately. A pipette bulb is
used to draw solution into the pipette.

Start by squeezing the bulb in your preferred hand. Then place the bulb on the flat end of
the pipette.
Place the tip of the pipette in the solution and release your grip on the bulb to pull solution
into the pipette. Draw solution in above the mark on the neck of the pipette. If the volume
of the pipette is larger than the volume of the pipette bulb, you may need to remove the
bulb from the pipette and squeeze it and replace it on the pipette a second time, to fill the
pipette volume completely.
Quickly, remove the pipette bulb and put your index finger on the end of the pipette. Gently
release the seal made by your finger until the level of the solution meniscus exactly lines up
with the mark on the pipette. Practice this with water until you are able to use the pipette
and bulb consistently and accurately.
