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. [4] The burette tube carries graduated marks from which the dispensed volume of the liquid can be determined. [5]

Feb 2, 2024 · What is Burette? A burette is a laboratory instrument designed for the accurate dispensing of small volumes of liquid or gases. It consists of a long, graduated glass tube equipped with a valve, typically located at one end, allowing precise control of the liquid flow.

Dec 13, 2024 · A burette is one of the most precise and indispensable tools in laboratories, playing a crucial role in experiments involving titration and other volumetric analyses. Though simple in design, its functionality requires a keen understanding to ensure accurate results.

Aug 21, 2023 · You must be at eye level with the bottom of the meniscus (curved surface of liquid) to read the burette. Reading from above or below the meniscus will result in a parallax error. In order to better read the meniscus, keep a dark piece of paper behind the buret.

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.

Une burette est un instrument de laboratoire permettant d'ajouter au goutte-à-goutte un réactif dont le volume (de l'ordre de 1 à 25 mL) doit être connu. C'est le cas lors d'un titrage volumétrique.

Dec 13, 2024 · A burette is a laboratory equipment used in chemistry to measure the volume of a liquid or a gas with high precision. It is a long, narrow tube with a stopcock at one end and a calibrated scale on the other end, allowing for accurate measurement of small volumes of …

Nov 14, 2024 · Burette is used to add titrant to the titrated solution and it has a scale on the side, so that you can precisely measure volume of the added solution. Burette is similar to the pipette, as it is designed to measure volume of the delivered liquid, but it …

A burette is a precise volumetric glassware used to dispense controlled amounts of liquid, typically during titrations. It features a long, narrow tube with a tap at the bottom, allowing for accurate measurement of liquid volumes to be added dropwise to a solution.

Apr 4, 2005 · Elle peut être effectuée à l'aide d'une pipette jaugée ou graduée, d'une burette graduée ou d'une fiole jaugée. Nous allons montrer dans cette séquence comment utiliser une burette graduée pour délivrer un volume précis de liquide.
