Burette: Types, Uses, Advantages, Limitations - Science Info
2024年2月2日 · A burette is a laboratory instrument designed for the accurate dispensing of small volumes of liquid or gases. It consists of a long, graduated glass tube equipped with a valve, typically located at one end, allowing precise control of the liquid flow.
Burette - Wikipedia
A burette (also spelled as buret) [1] is a graduated glass tube with a tap at one end, for delivering known volumes of a liquid, especially in titrations. It is a long, graduated glass tube, with a stopcock at its lower end and a tapered capillary tube at the stopcock's outlet.
Burette | Definition, Description, & Facts | Britannica
Burette, laboratory apparatus used in quantitative chemical analysis to measure the volume of a liquid or a gas. It consists of a graduated glass tube with a stopcock (turning plug, or spigot) at one end. On a liquid burette, the stopcock is at the bottom, and the precise volume of the liquid.
