A pipette is a laboratory tool used to measure and transfer small volumes of liquid, generally in milliliters or microliters. Micropipettes are a specialized type of pipette designed for very precise measurement and transfer of tiny liquid volumes, typically in the microliter range. They often feature adjustable volume settings, disposable tips for contamination prevention, and can be single-channel or multi-channel types for handling multiple samples simultaneously.

Pipettes broadly come in different forms such as glass, plastic, manual, or electronic devices used in various laboratory settings for accurate liquid handling. Micropipettes are essential in molecular biology, biochemistry, and clinical labs where precision in small volume liquid transfer is crucial. They can be fixed or variable volume types and operate by air displacement or positive displacement mechanisms, sometimes with electronic assistance for ease and accuracy.
