How does a normal pipette work?

Hello guys,

 

This might seem a basic question but my physics is not that good. So in a normal pipette when you squeeze the top bit, do you create an area of high pressure there, and then when you put in a flask with liquid and release it the air escapes, and then the atmospheric air pushes on the liquid and fluid comes into the pipette. Is that what happens? Thanks :)

When you squeeze the top bit it pushes out all the air, so when you release the bulb it creates a vacuum inside it which sucks up the liquid.
