A pipette is a laboratory instrument designed for measuring and transferring precise volumes of liquids. It typically consists of a slender tube with a narrow opening at the tip, which allows for accurate liquid handling. Pipettes can be manual, where the user controls the aspiration and dispensing of liquid, or electronic, which offer automated functions for precision. Different types of pipettes, such as micropipettes for small volumes and serological pipettes for larger volumes, are used depending on the requirements of the experiment. Pipettes are crucial tools in many scientific applications requiring precise liquid measurement and handling.
