Home / Burette, With Straight Bore Glass Stopcock
A burette is a laboratory equipment used in analytical chemistry for accurate dispensing of a measured volume of liquid. It is a long, narrow, cylindrical glass tube with a stopcock at the bottom and a graduated scale along its length. The stopcock controls the flow of the liquid and allows the user to dispense precisely measured volumes of the liquid.
Burettes are commonly used in titrations, where a solution of known concentration (the titrant) is added to a solution of unknown concentration (the analyte) until the reaction is complete. By measuring the volume of titrant added, the concentration of the analyte can be determined.
Burettes come in various sizes, with the most common sizes being 10 mL, 25 mL, and 50 mL. They can be made from various materials, such as glass or plastic, depending on the requirements of the experiment.
To use a burette, it is first filled with the liquid to be dispensed, with the meniscus at the zero mark on the scale. The stopcock is then opened and the liquid is allowed to flow until the meniscus reaches the desired volume on the scale. The stopcock is then closed to stop the flow of the liquid.
