1. a graduated glass tube with a tap at one end, for delivering known volumes of a liquid, especially in titration
Usage: also spelled burette (British English); commonly used in chemistry and laboratory settings

Examples

• The student carefully filled the buret with the standard solution before beginning the titration.
• A buret allows chemists to measure and dispense precise volumes of liquid.
• The buret's fine graduations make it ideal for accurate quantitative analysis.
• She opened the stopcock on the buret to release drops of the reagent into the flask.
• In the lab, we used a buret to deliver exactly 25 mL of the acid solution.
