Burettes are essential laboratory equipment used for delivering precise volumes of liquids. They consist of a long, graduated glass tube with a stopcock at the bottom for controlling the flow of liquid. Burettes are commonly used in titration experiments to measure the volume of a solution that has reacted completely with another.
Types of Burettes
There are two main types of burettes: the Mohr burette and the automatic burette. Mohr burettes are manually operated and require the user to control the flow of liquid by turning the stopcock. On the other hand, automatic burettes have a piston mechanism that allows for more precise control over the dispensing of liquids.
How to Use a Burette
When using a burette, it is important to first rinse it with the liquid that will be dispensed to ensure accurate measurements. The burette should be mounted securely on a stand with the stopcock at the bottom. Fill the burette with the liquid, making sure there are no air bubbles. Slowly open the stopcock to dispense the liquid until you reach the desired volume.
Maintenance and Calibration
Proper maintenance of burettes is crucial to ensure accurate measurements. They should be cleaned regularly with appropriate solvents and stored in a safe place to prevent breakage. Calibration should be done periodically to verify the accuracy of the burette's graduations and markings.
Burettes are precise instruments that are used in various laboratory applications, particularly in chemistry experiments. They provide accurate measurements of liquids and are essential for titration procedures. By understanding how to use and maintain burettes properly, scientists can ensure reliable results in their experiments.
Burettes Examples
