Burettes
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. The flow of liquid from the tube to the burette tip is controlled by the stopcock valve.
There are two main types of burette; the volumetric burette and the piston burette. A volumetric burette delivers measured volumes of liquid. Piston burettes are similar to syringes, but with a precision bore and a plunger. Piston burettes may be manually operated or may be motorized.[2] A weight burette delivers measured weights of a liquid.[3]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.
