What is more accurate than a pipette?
a pipette is more accurate than a graduated cylinder due to allowing a greater amount of control on how much fluid you want. With a graduated cylinder, you pour the fluid into it, and risk accidentally pouring in too much or not enough, causing you to have to pour some out or add still more. With a pipette, the control mechanism (depends on type of pipette), allows far greater control over how much and how fast you want to add fluid. Any errors therefore, tend to be smaller and easier to remedy.
