What is a pipette?

• A. A glass or transparent plastic tube used to accurately measure small amounts of liquid
• B. A device used to mix chemicals
• C. A device for weighing solids
• D. A thermometer

Answer: (A)

A pipette is a lab tool designed to accurately transfer small volumes of liquid. It’s typically made of glass or clear plastic and has markings to read the exact amount you’re drawing and releasing. The emphasis is on precision—you can draw up a specific volume and dispense it so the amount moved is exact, which matters a lot in experiments. There are different forms, from simple glass pipettes used for transferring liquids to adjustable micropipettes that can set precise volumes across a wide range. This tool is about careful liquid handling, not about mixing substances, weighing solids, or measuring temperature, which are done with other instruments.
