_____ pipettes are used for performance monitoring and should be ______

• A. Volumetric, Class A
• B. Serological, Class 1
• C. Mohr, NSF Approved
• D. Buchner, Class 1

Answer: (A)

For performance monitoring, you need a tool that delivers a known, exact volume with the highest possible accuracy. Volumetric pipettes are built to transfer one precise volume, and when they are Class A, they meet the tightest tolerances used in quality control. This combination provides the most reliable, repeatable results for verifying instrument performance. Other pipette types are less suited for this purpose. Serological pipettes can deliver varying volumes and carry looser tolerances, Mohr pipettes are designed for approximate delivery rather than a single fixed volume, and Buchner items are used for filtration rather than precise volume transfer. Certification like NSF approval relates to compliance, not the precision class needed for performance monitoring.
