buret
Noun: A buret is a laboratory instrument used for precise measurement and dispensing of liquids. It consists of a long, graduated glass tube with a stopcock (a tap or valve) at its bottom end. Its primary function is to deliver variable, measurable volumes of a liquid, most commonly during the analytical procedure known as titration.
The word buret is used as a countable noun. It refers to the specific piece of laboratory glassware. * Always ensure the buret is clean and properly calibrated before use. * The chemist carefully read the meniscus on the buret to record the initial volume. * A 50-milliliter buret is standard for many acid-base titrations.
- Noun:
- She clamped the buret vertically to the ring stand.
- The buret's stopcock allows for very controlled addition of the titrant.
- Accurate results depend on correctly reading the graduations on the buret.
- "To deliver from a buret": This is the standard phrase for dispensing a liquid using this instrument, emphasizing the act of measurement.
- The student delivered 22.5 mL of sodium hydroxide solution from the buret into the flask.
- Burette: This is a common alternative spelling, especially in British English. The meaning is identical.
- Titration: (n) The analytical technique for which a buret is most essential.
- Stopcock / Tap: (n) The controllable valve at the base of the buret.
- Meniscus: (n) The curved surface of a liquid in a tube, which must be read correctly for accurate volume measurement.
- Graduated Cylinder: (n) Another piece of glassware for measuring liquid volume, but it is for a single volume, not for precise dispensing.
- Measuring tube: A more general, descriptive term.
- Titration buret/burette: A more specific term highlighting its primary function.
Note: There are no specific idioms or phrasal verbs associated with the highly technical noun "buret."
