A micropipette is a laboratory tool used to measure and transfer small volumes of liquid, typically in the range of 0.1 to 1000 microliters. It consists of a plunger, a barrel, and a disposable tip, allowing for precise and accurate liquid handling. Micropipettes are essential in various fields, including biology, chemistry, and medicine, where accurate measurements are crucial for experiments and analyses. These devices come in different types, such as single-channel and multi-channel micropipettes, which can dispense multiple samples simultaneously. Proper use and calibration of a micropipette are vital to ensure reliable results in scientific research and clinical applications.
