burette, laboratory apparatus used in quantitative chemical analysis to measure the volume of a liquid or a gas. It consists of a graduated glass tube with a stopcock (turning plug, or spigot) at one end. On a liquid burette, the stopcock is at the bottom, and the precise volume of the liquid dispensed can be determined by reading the The burette is typically used in titrations, a common analytical technique employed in chemistry to determine the concentration of a substance in a solution. With its remarkable precision, the burette allows scientists to add the titrant gradually until the endpoint of the reaction is reached. The chaos and production of small bubbles (right) is often capable of driving out all bubbles from the nozzle. If that doesn't work, immerse the nozzle of the buret in a small beaker of titrant and while using the bulb to reverse the flow of titrant, open the valve (right). During a Titration, keep the liquid flowing normally until a few mL from the endpoint (the point at which the color changes). Around the endpoint, allow the liquid to flow drop-by-drop. After reaching the endpoint, rinse and dry the tip of the burette. burette close burette A piece of apparatus used to add varying but measured volumes of solution during a titration. pipette close pipette A piece of apparatus used to measure accurate and If the burette is not completely dry by the time you use it, the remaining traces of water on the inside will make your titrant more dilute and thereby change its concentration. Consequently, if you don't rinse your burette with titrant and there really is some water remaining inside, the titrant you dispense will be more dilute than it should be. A burette is used to accurately measure the volume of liquid that has been allowed to pour out of it. A burette is a volumetric measuring glassware which is used in analytical chemistry for the accurate dispensing of a liquid, especially of one of the reagents in a titration. The burette tube carries graduated marks from which the dispensed volume of the liquid can be determined.
