Which item is a tiny disposable tip used with automated pipettes?

• A. Microcentrifuge Tubes
• B. Micropipette Tips
• C. Peg Rack
• D. Petri Dish

Answer: (B)

The concept here is about the consumable that attaches to automated pipettes to enable precise, contamination-free transfer. The tiny disposable item described is a micropipette tip—the small plastic cone that fits onto the end of a pipette to draw up and dispense exact volumes. These tips come in different sizes to match the pipette’s volume range and can be filtered or non-filtered to reduce aerosol carryover. They are typically sterile and discarded after each use to prevent cross-contamination between samples. Microcentrifuge tubes are used for holding samples during centrifugation, peg racks organize tubes, and Petri dishes are used for cultivating cultures. So the item described is the micropipette tip.
