Which instrument is used for measuring and transferring small volumes of liquids?

• A. Desiccator
• B. Pipette
• C. Beaker
• D. Volumetric flask

Answer: (B)

A pipette is designed to measure and transfer small, controlled volumes with high precision. It works by drawing a specific amount of liquid into a calibrated tip or reservoir and then dispensing that exact amount into another container, which is essential for accurate measurements in experiments and sample prep.

Desiccators are used to keep items dry, not for measuring liquids. Beakers are general-purpose containers with rough volume markings and are not precise enough for small-volume transfers. Volumetric flasks are calibrated to contain a precise volume when filled to a mark, making them ideal for preparing standard solutions, but not for delivering small, measured portions directly from the source.
