burette
C2Technical/Scientific
Definition
Meaning
A graduated glass tube with a tap at one end, used in chemical laboratories for delivering known volumes of a liquid, especially in titrations.
Beyond its core definition, 'burette' can refer to similar precision liquid-dispensing devices in other fields, such as pharmacy or industrial quality control.
Linguistics
Semantic Notes
Exclusively a piece of laboratory equipment. It is a specific type of volumetric glassware, distinguished from a pipette or measuring cylinder by its tap/stopcock and its function of adding a titrant dropwise.
Dialectal Variation
British vs American Usage
Differences
Spelling: 'Burette' is the standard British spelling. American English uses both 'buret' and 'burette', with 'buret' being more common in technical/scientific contexts, while 'burette' is recognized and sometimes used.
Connotations
No difference in connotation; purely a technical term. The choice of spelling may subtly signal adherence to UK or US scientific publishing conventions.
Frequency
The word is very low-frequency in general language but standard and frequent within chemistry laboratory contexts in both varieties.

Examples
By Part of Speech
verb
British English
- The chemist will burette the sodium hydroxide solution into the acid.
American English
- After standardizing, she buretted the HCl into the sample.
adjective
British English
- The burette clamp was secured firmly to the stand.
American English
- He checked the buret reading under the meniscus.
Examples
By CEFR Level
- In the chemistry lab, we used a burette to add acid to the alkali drop by drop.
- Make sure the burette is clean and the tap moves freely before you start the experiment.
- The endpoint of the titration was determined by a persistent colour change after the careful, dropwise addition of titrant from the calibrated 50 ml burette.
- Prior to use, the burette was rinsed with three aliquots of the titrant solution to prevent dilution errors.
Learning
Memory Aids
Mnemonic
Think: 'You BET you need a BUREtte to measure liquids with precision in a lab.' It rhymes with 'bet' and is a precise tool you can bet on.
Conceptual Metaphor
Often conceptualised as a 'precision tap' or a 'measuring syringe' for scientists.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid confusing with 'пипетка' (pipette, dropper). A burette has a tap and is for delivering variable volumes; a pipette is often for transferring a fixed volume.
- Avoid associating it with the unrelated French word 'bureau' (desk, office).
Common Mistakes
- Mispronouncing it as /ˈbjʊərɪt/ or /ˈbɜːrɪt/. The stress is on the second syllable.
- Misspelling as 'burrette' or 'buerette'.
- Confusing it with a 'graduated cylinder' (which has no tap).

FAQ
Frequently Asked Questions
Both are accepted. 'Burette' is the standard British English spelling, while 'buret' is common in American English technical writing.
A burette has a tap (stopcock) at the bottom to deliver variable, measurable volumes of liquid. A pipette (like a volumetric pipette) is typically used to transfer a single, fixed volume of liquid, often by suction.
In British English: /bjʊəˈrɛt/ (byoo-RET). In American English: /bjʊˈrɛt/ (byoo-RET) or /bəˈrɛt/ (buh-RET). The stress is always on the last syllable.
Almost exclusively in chemistry—specifically in analytical chemistry, titration experiments, laboratory manuals, and scientific research papers. It is not a word used in everyday conversation.
