Burette vs. Pipette: What's the Difference?
A burette is a graduated glass tube with a tap for delivering known volumes of a liquid, while a pipette is a slender tube for transferring or measuring small volumes of liquid.
A burette is a long, cylindrical glass tube with graduation marks and a valve or stopcock at the bottom, allowing controlled liquid release. A pipette, in contrast, is typically a slender glass or plastic tube, sometimes with a bulb, used for transferring or measuring small liquid amounts.
Burettes are designed for dispensing variable, but precise, volumes of liquid, often used in titrations where accuracy is critical. Pipettes are used for accurately measuring and transferring fixed volumes, essential in many laboratory procedures.
In a laboratory, a burette is commonly used in quantitative chemical analysis, especially titration, to determine unknown concentrations. Pipettes are used in various laboratory applications, from chemistry to biology, for transferring precise volumes of liquids.
There are different types of burettes, like straight and digital burettes. Pipettes come in several forms, including volumetric, graduated, and Pasteur pipettes, each serving specific purposes.
Operating a burette involves adjusting the valve or stopcock to control liquid flow. Pipettes require the use of a pipette filler or a bulb to draw and release liquid.
