burette

A burette is a piece of laboratory equipment that is used to measure and dispense small amounts of liquid.

A burette is a long, graduated tube with a stopcock at the bottom. The stopcock is a valve that controls the flow of liquid from the burette. The graduations on the burette allow you to measure the volume of liquid that has been dispensed.

Burette is used in titrations, which are a type of chemical analysis. In a titration, a known volume of a solution of known concentration is added to a solution of unknown concentration until the reaction is complete. The volume of the known solution that is added is used to calculate the concentration of the unknown solution.

Burette is a safe piece of equipment when used properly. However, there are some safety precautions that should be taken when using a burette. These precautions include:

• Always wear safety goggles when using a burette.
• Never leave a burette unattended.
• Turn off the stopcock when you are finished using the burette.
• Do not point the burette at yourself or other people.
