A pipette is a laboratory tool used to measure and transfer small volumes of liquids accurately. It typically consists of a slender tube with a bulb at one end, allowing users to draw liquid into the tube by creating suction. Pipettes come in various sizes and types, including manual pipettes and electronic pipettes, making them versatile for different scientific tasks. In research and medical labs, pipettes are essential for experiments, sample preparation, and testing. They help ensure precision when working with tiny amounts of liquids, which is crucial in fields like biology, chemistry, and medicine. Proper use of pipettes can significantly impact the accuracy of results.
