buret

Graduated glass cylinder

A buret is a graduated glass tube with a valve at the bottom, used in chemistry to dispense precise volumes of liquid.

The device is essential for titration, where you add measured amounts of one solution to another until a reaction completes: She read the buret to determine exactly how much acid had been dispensed.

Also spelled burette.
