Which instrument is the most basic pipet?

• A. Pipette Controller
• B. Burette
• C. Micropipette
• D. Glass Pipet

Answer: (D)

The idea here is understanding how pipetting tools differ in complexity and precision. A glass pipet is the most basic option because it’s just a plain glass tube used to transfer liquids, typically without any calibrated marks or internal mechanisms. It relies on simple manual suction and estimation, so it offers no precise volume control. In contrast, a micropipette is designed for accurate, small-volume measurements with calibrated settings and a precise plunger mechanism. A pipette controller is merely a device to help create suction for a pipette, not a pipet itself. A burette is a separate instrument used for titration with detailed volume graduations, not a pipet. So, the glass pipet is the most basic pipetting instrument.
