Etymology
Origin of pipette
From French, dating back to 1830–40; see origin at pipe 1, -ette
Explanation
One of the tools in a chemistry lab is a pipette, a glass tube used to move liquids. If you were examining a chemical under your microscope, you'd use a pipette to put a drop on your slide. Some pipettes are used for measuring small amounts of liquid, but the most common use is transporting them from one place to another. When you squeeze a small bulb attached to the pipette, the vacuum you've created sucks fluid up into the slender glass instrument. Think of an eye dropper, the most commonly-used type of pipette. The word comes from Middle French, in which it means "tube."
