Which item is a very fine pipette used for measuring small quantities?

• A. Micropipetter
• B. Pipette-Aids
• C. Microcentrifuge
• D. Inoculating Loop

Answer: (A)

Measuring tiny amounts with precision is what a micropipette is built for. It lets you set an exact volume and draw that amount into a disposable tip, delivering very small quantities in microliters with high accuracy. This precision is crucial in experiments where even small volume changes can alter results, such as preparing reagents or running PCR. The other tools aren’t used for measuring small volumes: pipette aids help you handle a pipette but don’t measure volumes themselves; a microcentrifuge is for spinning samples to separate components; an inoculating loop is for transferring microorganisms, not for precise liquid measurement.
