Pasteur Pipette
Pasteur pipettes, also known as teat pipettes or droppers, are plastic or glass pipettes used to transfer small amounts of liquids, but are not graduated or calibrated for any particular volume. Transfer pipettes, also known as Beral pipettes, are similar to Pasteur pipettes. However, they are made from a single piece of plastic and their bulb can serve as the liquid-holding chamber.
A commercial variant of the pasteur pipette is the disposable pipette which is often made of plastic and intended to be used to administer medicine into the eye or ear of a patient (see image).

“There does not exist a category of science to which one can give the name applied science. There are science and the applications of science, bound together as the fruit of the tree which bears it.”
