A pipette is a laboratory instrument used to measure and transfer precise volumes of liquids. It consists of a narrow tube with a tapered tip and a piston or plunger mechanism. Pipettes come in various types, including micropipettes, which measure volumes in microliters (µL), and serological pipettes, which measure volumes in milliliters (mL). They are essential tools in biology, chemistry, and medical laboratories for tasks such as dispensing reagents, preparing samples, and conducting experiments with high accuracy and precision. Pipettes are available in single-channel and multi-channel configurations, offering versatility and efficiency in liquid handling tasks. Proper calibration, technique, and maintenance are crucial for accurate and reproducible results.
