What can be called a 'graduated pipette'

• A. Transfer Pipet
• B. Serological Pipette
• C. Test Tube Brush
• D. Stoddard Clamp

Answer: (B)

A graduated pipette has measurement marks along its length, allowing you to read and deliver a specific volume with precision. The serological pipette is designed with graduations extending all the way to the tip, which enables precise measurement of the liquid you dispense, making it a classic example of a graduated pipette. A transfer pipet, on the other hand, is typically ungraduated and used mainly to move droplets or very small volumes without precise measurement. The test tube brush and the Stoddard clamp are not pipettes at all; they are a cleaning tool and a lab support clamp, respectively.
