What are the differences between a volumetric pipette and a serological pipette in terms of their design and usage in laboratory settings?

A volumetric pipette is designed for precise measurement of a specific volume of liquid, typically with a single graduation mark. It is used for accurate transfer of liquids in laboratory settings. On the other hand, a serological pipette is designed for general liquid transfer and has multiple graduation marks for different volume measurements. It is commonly used for less precise measurements and general liquid handling in the lab.
