Which instrument is used to measure small volumes of liquid?

Explanation:
When you need to handle small amounts of liquid with precision, you use an instrument that can set and deliver an exact volume. A pipette does exactly this: you set the volume, draw liquid into a tip, and dispense that precise amount. This makes it much more accurate for small volumes than other tools. Beakers are for rough measurements and mixing, rulers measure length, and a graduated cylinder is good for larger volumes but not as precise for tiny amounts. So, the pipette is the best choice for small-volume measurements.
