What are the key differences between a pipettor and a pipette, and how do these differences impact their functionality in a laboratory setting?

A pipettor is a device used to dispense precise volumes of liquid, typically electronically controlled, while a pipette is a glass or plastic tube used to transfer specific volumes of liquid manually. The key difference is the method of operation, with a pipettor offering more accuracy and consistency in volume dispensing compared to a pipette. This impacts their functionality in a laboratory setting by allowing for more precise and reliable measurements when using a pipettor, which is essential for experiments requiring exact volumes of liquids.
