pipet
Definition
Noun: A pipet (also spelled pipette) is a laboratory tool. It is a slender, usually transparent, tube. It is used to accurately measure and transfer a specific, often small, volume of liquid from one container to another. This is done by drawing the liquid up into the tube using suction.
Usage
A pipet is a fundamental instrument in scientific and medical laboratories. It is used when precise liquid handling is required, such as in chemistry experiments, biology assays, or medical tests.
Examples
- Noun:
- The chemist used a glass pipet to add exactly 5 milliliters of the reagent to the test tube.
- For this procedure, you will need a sterile plastic pipet to avoid contamination.
- She carefully released the liquid from the pipet drop by drop.
