What are the key differences between a serological pipette and a volumetric pipette in terms of their accuracy and precision in measuring liquid volumes?

Serological pipettes are generally more accurate and precise than volumetric pipettes when measuring liquid volumes. Serological pipettes have graduations along the entire length, allowing for more precise measurements, while volumetric pipettes have a single graduation mark, which can lead to slightly less accuracy. Additionally, serological pipettes are typically calibrated to deliver a specific volume, while volumetric pipettes are calibrated to contain a specific volume.
