A burette is a graduated glass or plastic tube with a stopcock at the bottom, used in chemistry to precisely measure and dispense variable volumes of liquid, most commonly in titrations. It enables accurate control and measurement by reading the difference between the initial and final volume markings.

Key Features and Uses
Design
An elongated, narrow, graduated tube (volume markings), with zero at the top, equipped with a stopcock valve at the bottom for precise flow control.
Function
Designed to dispense variable amounts of liquid, unlike a pipette which typically delivers a fixed volume.
Primary Use
Widely used in analytical chemistry, especially for titrations to determine an unknown concentration by reaching the equivalence point with high precision.
Types
- Standard manual burettes (glass or plastic)
- Digital burettes (piston-based or automated)
