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 clamp is a scientific equipment which used specifically to hold and secure a burette on a stand, so that a burette is fixed and more convenient for the experiment. [1] Burette clamps can be made with many materials such as plastic and cast iron. However, an iron clamp with a rubber knob to hold the burette are usually more durable.
