A burette is a laboratory equipment used to deliver precise amounts of liquid over a certain period of time It is calibrated in milliliters and is commonly used to conduct titrations, a laboratory technique used to measure the volume of one solution that is necessary to react with the other. A burette is composed of a graduated glass tube with a stopcock at the lower end and an open top. The stopcock or valve is usually made of a material like Teflon or PTFE, which are inert and do not react with the liquid, and allows for a smooth and controlled flow of the liquid. The burette is calibrated according to the volume of liquid that it holds and typically ranges from 1-50 mL.
