Which disposable item is used to transfer very small volumes of liquid, often for single use?

• A. Beaker
• B. Florence Flask
• C. Bottle
• D. Disposable Pipette

Answer: (D)

Transferring very small volumes cleanly and with minimal risk of contamination is what disposable pipettes are designed for. They are slender plastic tools used to draw up and release tiny amounts of liquid, and being disposable means they’re used once and discarded, which helps prevent sample carryover and maintains accuracy.

The other items don’t fit this usage: a beaker is for holding and pouring larger amounts and isn’t precise for small volumes; a Florence flask is designed for heating or mixing with a rounded body and narrow neck; a bottle is mainly for storage. So the disposable pipette is the best choice for small-volume transfer.
