volumetric pipette vs graduated cylinder

  • Differences Between Volumetric Pipettes and Graduated

    However there are differences in accuracy demarcation styles and volume capacity. Graduated pipettes can generally allow for different measurements of liquid to be transferred from one place to another. A volumetric pipette allows for only a specific or fixed amount of solution to be transferred.
