What is pipette and burette?

The burette is a long glass cylinder with an open top and a stopcock at the bottom to prevent internal liquid from escaping the burette. The tube has volumetric markings to allow the user to extract only the amount of liquid needed for a specific chemical process.

In addition, there are burettes of different sizes, which allow us to use different amounts of liquid. If using a 5 ml burette and dosing the liquid drop by drop by releasing the stopcock, the amount used is determined by subtracting the final value from the 5 ml burette.

A pipette is a laboratory tool; We often use it in chemistry, biology, and medicine to transport a measured volume of liquid, usually as a media dispenser. In some fields of study, such as molecular biology and analytical chemistry, we need to dose the smallest amounts of liquid. There are devices that help to dispense just the amount of liquid we need. One such device that gives you complete control is an eyedropper. It’s like a syringe in a laboratory; that’s why we also call it a chemical dropper.

Pipettes and Burettes  are analytical tools. However, the main difference between the burette and the pipette is in the triggering mechanism. Thus, the burettes have a tap at the bottom, while the pipette has a dropper-type system that dispenses the liquid in the desired amount, reducing the vacuum.

What are the pipette and burette for? What are the pipette and burette experiment?

Both are used for titration.

Titration or titrometry is a common laboratory procedure used in the quantitative analysis of an analyte (a chemical substrate), which is usually acidic in acid-base titration.

Titrant: A solution of known concentration is called a titrant. The burette contains the titrant which is slowly released into the analyte in the Erlenmeyer flask.

Titration: The chemical substrate with an unknown concentration is called titration. The titleholder is on the ball.

Endpoint/equivalence point: The endpoint or equivalence point is the point at which complete neutralization of the ethic acid with the base occurs. To measure the endpoint, various color-changing indicators are used. The color change is called the endpoint.

Why Burette And Pipette Is Rinsed?

The burette and pipette are rinsed to avoid contamination and thus maintain test accuracy.
