What is the importance of micropipettes?

• A. To measure large volumes
• B. To grind solid samples
• C. To transfer very small and exact volumes of reagents
• D. To incubate samples at high temperature

Answer: (C)

Micropipettes are designed to transfer very small and exact volumes of liquids. In experiments, working with tiny amounts in the microliter range means that even small errors can drastically change concentrations and the outcome of a reaction. The ability to set an exact volume and use disposable tips helps ensure precision, accuracy, and contamination prevention between steps. Proper technique—pre-wetting tips, smooth pipetting, and avoiding air bubbles—further improves reliability, which is crucial when handling reagents that are potent or costly. The other tasks described don’t fit what a micropipette does: measuring large volumes requires larger tools, grinding solids uses a mortar and pestle, and incubating at high temperatures is done with a heat source or incubator, not a pipette.
