a pippete is used to add a few drops of a solution (no measurement) whereas a burette is used to add accurate quantity of solution

let me clear that

Burette- A long glass tube with a tap on the end. The tube is marked every 1 cm3 with smaller graduations of 0.1cm3. It is used in titrations to accurately measure small volumes (upto 50cm3) of liquid.


Pipette-A piece of glassware used for measuring  and transferring a fixed volume of liquid.

and godfather there r pipettes that measure 50cm3too. I've seen them in my lab. And actually we have used  25cm3 pipettes for our practical experiments.

kam the dropper is also called a teat pipette. that's a teat pipette
