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.

Aug 1, 2016 · make sure the jet space in the burette is filled with the solution and air bubbles are removed. If the jet space in the burette is not filled properly prior to commencing the titration it will lead to errors if it then fills during the titration, leading to a larger than expected titre reading. Read the bottom of the meniscus on the burette

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.

The signs of a dirty burette are a flat meniscus and poor draining with solution droplets clinging to the side of the glass. These droplets should have been delivered from the burette. The easiest solution is to get another (clean!) burette. Air bubble in jet. This may well fill during the titration and increase the reading on the burette.

Dec 13, 2024 · What Is a Burette? A burette is a graduated glass or plastic tube with a stopcock at its lower end, used to deliver precise volumes of liquid during titration experiments. Its design ensures controlled release of liquid, allowing researchers to measure volume changes accurately, often to the nearest 0.01 milliliter (mL). Key Features of a Burette:

Jul 7, 2024 · Burettes, long glass tubes with volume markings and a stopcock at the bottom, provide precise control over liquid flow. Chemists commonly use burettes to accurately dispense liquids for titrations, determining the concentration of a solution.

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.

Jun 17, 2023 · A buret is a glass apparatus for delivering precise, variable volumes of solution. It is primarily used for titration to determine the concentration of an unknown solution by adding a solution of known concentration.

Burette: Devices commonly used in an analytical laboratory to dispense variable, measured amounts of a chemical solution. A volumetric burette delivers measured volumes of liquid.

The Burette How to use it 1. Fix the burette into the burette holder, taking care that it is vertical and stable. Place a beaker underneath the burette. 2. Close the tap, and run some de-ionised water into the top of the burette. Let the water clean the inside of the burette. Open the tap, and allow the water to drain out. Repeat. 3.
