A burette is a long, graduated glass tube with a stopcock at the bottom used in analytical chemistry for accurately measuring and dispensing liquid solutions. It is commonly used in titrations to measure the volume of a liquid added to a reaction mixture. The burette allows for precise control and measurement of the volume of liquid being dispensed, making it a valuable tool in quantitative analysis.

Burette is a laboratory equipment used in volumetric analysis to accurately measure and dispense known volumes of liquid.
Uses:
- Precise Liquid Measurement: Burettes are used to measure the volume of a liquid precisely. They are calibrated with a high degree of accuracy, allowing for precise measurements in analytical chemistry and titration experiments.
- Controlled Liquid Dispensing: Burettes can be used to dispense precise volumes of liquids over time. This feature is essential in titrations, where small increments of reagents need to be added to the reaction mixture.
- Titrations: Burettes are the primary tool used in titrations. They are used to deliver a known volume of titrant (the solution whose concentration is known) to the analyte (the solution whose concentration is being determined).
- Acid-Base Titrations: Burettes are used to measure the exact amount of base or acid added to neutralize the analyte in acid-base titrations. This allows for the determination of the concentration of the unknown solution.
- Redox Titrations: Burettes are used to dispense reducing or oxidizing agents in redox titrations. They help quantify the amount of oxidizing or reducing agent in a sample.
- Complexometric Titrations: Burettes are used to deliver ligands that form complexes with metal ions in complexometric titrations. This allows for the determination of the concentration of metal ions in a solution.
- Microbiological Analysis: Burettes are used to dispense precise volumes of media, reagents, and bacterial cultures in microbiological analysis.
- Other Volumetric Analysis: Burettes can be used in various other volumetric analysis techniques, such as precipitation reactions and gravimetric analysis.
