Pipetting is used to quantitatively transfer a liquid from one container to another.
The volumetric pipette has a single graduation that allows it to deliver one specific volume accurately. There are many different sizes of volumetric pipette (1-, 5-, 10-, 25-, 50-, and 100-mL volumetric pipette are common). A volumetric pipette is accurate at the temperature at which it has been calibrated. The temperature where the volume is accurate is usually printed on the neck of the pipette. If you are working at a different temperature, the volumetric pipette should be calibrated.
