A smaller, less accurate version, known as a teat pipette is made of plastic and is filled by squeezing a plastic bubble at the top.
A pipette used for the delivery of small fractions of a milliliter of a liquid is called a micropipette.
Piston-driven air displacement pipettes, or 'micropipettes', are the most accurate and precise pipettes. They handle liquid in the microliter scale, and are used in biology and biochemistry,
