The glass pipette


There are two types of glass pipettes: graduated pipettes and volumetric pipettes.

Graduated pipettes can be used to collect a given volume with medium precision. Volumetric pipettes are used to transfer a fixed volume, with excellent precision; there are different volumes (usually 1.0 - 2.0 - 5.0 - 10.0 - 20.0 - 25.0 mL).


Pipettes are used to collect liquids and prepare solutions. It is necessary to use either a rubber pipette filler, or a pipette pump, to withdraw the desired volume with a glass pipette.
