Manual pipettes are laboratory tools used to transfer precise volumes of liquids. They consist of a slender tube with a plunger that creates suction, allowing users to draw liquid into the pipette and dispense it accurately. Manual pipettes are commonly used in scientific research, medical testing, and educational settings. These devices come in various sizes and types, including micropipettes for small volumes and serological pipettes for larger amounts. Proper technique is essential for accuracy, and users often calibrate their pipettes to ensure reliable measurements. Manual pipettes are essential for experiments that require precision in liquid handling.
