Burettes and Pipettes are the most commonly used science laboratory equipments. These are mainly used in Chemical/Chemistry laboratories. They are mainly used for the titration purposes in the chemical industry.
Burette is a glass cylinder that is long and open at the top with a stop cock at the bottom to prevent the liquid filled in it from escaping from the burette. The tube has volumetric markings to allow the user to take only as much liquid as is desired in a particular chemical process. There are different size burettes to allow different quantities of liquid to be used.
Pipettes, also called pipets or chemical droppers, are small tubes of glass or plastic used to transfer a measurable amount of liquid from one container to another. They come in two forms: volumetric pipettes, used to transfer a single specific volume of liquid, and measuring pipettes, used to transfer varying, measured volumes.
- Pipette is smaller than burette.
- Release mechanisms are different in pipettes and burettes; burettes have a stop cock at the bottom while a pipette has a dropper like system that releases liquid in desired amount by lessening the vacuum.
- Pipettes are believed to be more accurate in releasing liquid in smaller quantities than burettes.
