Which item is a very fine pipette for measuring, transferring, or injecting very small quantities of liquid?

• A. Microcentrifuge
• B. Pipette-Aids
• C. Micropipetter
• D. Petri Dish

Answer: (C)

Precise handling of very small liquid volumes is done with a micropipette. This instrument is built to measure, transfer, or even inject tiny amounts by letting you set a calibrated volume and use a disposable tip to aspirate and dispense with control and accuracy. It’s designed for repeatable measurements, which is essential when you’re working with microliter quantities in experiments. The other items aren’t meant for precise small-volume work: a microcentrifuge is meant for spinning samples to separate components, not for measuring; pipette aids help guide or assist pipetting but don’t provide the actual precise measurement; a Petri dish is used for growing or inspecting cultures, not for measuring or transferring liquids. So the tool designed for very fine, accurate liquid handling is the micropipette.
