Which disposable item is used to transfer small volumes of liquid?

• A. Beaker
• B. Disposable Pipette
• C. Bottle
• D. Centrifuge

Answer: (B)

Transferring small volumes with accuracy requires a tool that can aspirate and dispense precise amounts. A pipette is designed for this task, and disposable variants are ideal because they’re single-use and reduce contamination between samples. In lab practice, pipettes (especially micropipettes) handle tiny volumes very precisely, from microliters up to a few milliliters, making them the go-to choice for small-volume transfers. By contrast, a beaker is a general-purpose container for holding, measuring larger volumes and for mixing or heating; a bottle is used mainly for storage; and a centrifuge is a device for spinning samples to separate components, not for transferring liquids. Therefore, the disposable pipette is the best choice for moving small amounts of liquid.
