Pipette
Pipette (pronounced: pi-pet) is a laboratory tool commonly used in chemistry, biology, and medicine to transport a measured volume of liquid.
Etymology
The term "pipette" comes from the French word pipette, which is a diminutive form of pipe, meaning a small tube.
Description
A pipette is often a slender tube attached to a bulb or piston at one end, which is used to draw up and dispense precise amounts of liquid. There are several types of pipettes, including volumetric pipettes, graduated pipettes, and micropipettes, each designed for specific tasks and volumes.
Usage
In medicine, pipettes are often used in laboratory tests and experiments to handle small amounts of liquids. They are essential in procedures such as DNA sequencing, PCR, and cell culture. In chemistry, pipettes are used to accurately measure and transfer liquids in experiments and analyses.
