A pipette is a laboratory tool used to transport a measured volume of liquid. It typically consists of a slender tube with a bulb or plunger at one end, allowing for precise control of liquid transfer. Pipettes are essential in various scientific fields, including chemistry, biology, and medicine, where accurate measurements are crucial. There are different types of pipettes, such as manual pipettes and automated pipettes. Manual pipettes require the user to operate them by hand, while automated pipettes can dispense liquids with minimal user intervention. Both types are vital for experiments, ensuring consistency and accuracy in liquid handling.
