Burette

We are offering Burette. a burette (also buret) is a vertical cylindrical piece of laboratory glassware with a volumetric graduation etched permanently on its full length and a precision tap, or stopcock with plug and bore, on the bottom. the commonly used stopcocks can be a ground-glass barrel or a plastic plug made of ptfe, depending on the liquid to be carried. it is used to dispense known amounts of a liquid reagent in experiments for which such precision is necessary, such as in a volumetric analysis. burettes are extremely accurate, and have very small accuracy tolerances.
