A micropipette is a versatile laboratory instrument used to transfer small volumes of liquid, typically in the microliter range. Single-channel micropipettes are commonly employed in fields like molecular biology, microbiology, immunology, and cell culture, while multi-channel micropipettes are better suited for high-throughput processes such as ELISA testing, molecular screening, and DNA amplification. Proper selection of micropipette tips is essential for achieving accurate results in liquid handling.
