Burette

Meaning in chemistry, with examples

/bjʊˈret/nounCommon term

In chemistry, burette means: A long, graduated glass tube with a tap (stopcock) at the bottom, used to add a liquid gradually and measure exactly how much was added, mainly in titrations.

In Turkish: büret

How it is used

A standard titration tool. You rinse, fill, clamp and read a burette, record the initial and final readings, and read it at eye level at the bottom of the meniscus. The US spelling is 'buret'.

Example sentences

  1. Rinse the burette with a little of the NaOH solution before filling it.

  2. The burette reading was 23.45 mL at the endpoint.

Common collocations

  • burette reading
  • fill the burette
  • burette stand
  • burette tap
  • 50 mL burette
  • titrationA method for finding the unknown concentration of a solution by adding a solution of known concentration from a burette until the reaction between them is just complete.
  • pipetteA thin glass or plastic tube used to measure and transfer a precise volume of liquid. Volumetric types deliver one fixed volume; micropipettes handle microliters.
  • endpointThe point in a titration where the indicator changes color or the signal changes sharply, showing that the reaction is complete and you should stop adding titrant.
  • standard solutionA solution whose concentration is known accurately. It is used to find the concentration of other solutions in titrations or to build calibration curves.
