Which instrument is designed to transfer a small volume of liquid?

• A. Burette
• B. Beaker
• C. Graduated cylinder
• D. Transfer pipette

Answer: (D)

Transferring a small, precise amount of liquid is best done with a transfer pipette. Its tiny tip and suction-capability let you pick up a defined, small volume and move it to another container with minimal leftover liquid, which is essential when you’re preparing dilutions or adding an exact aliquot to a reaction.

A beaker is a general-purpose container used for holding, mixing, or rough measuring, not for precise transfers. A graduated cylinder is designed to measure volume accurately, not primarily to transfer a small amount. A burette is built for delivering controlled volumes during titration, not just for transferring a small amount. So the transfer pipette specifically serves the purpose of moving small volumes.
