pipet

A scientist uses a pipet to transfer a clear liquid into a test tube.

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.
Advanced Usage
  • "To pipet" (verb, derived from noun): The act of using a pipet to transfer liquid.
    • You must pipet the sample into the well very carefully.
  • "Pipetting": The technique or action of using a pipet.
    • Proper pipetting is essential for obtaining accurate results.
Variants and Related Words
  • Pipette: The more common alternate spelling of "pipet." The meanings are identical.
  • Micropipette (n): A very precise type of pipet designed to measure and transfer extremely small volumes, typically in the microliter (µL) range.
  • Dropper pipet (n): A simple pipet with a rubber bulb used to transfer liquids in drops.
  • Volumetric pipet (n): A pipet designed to deliver one specific, highly accurate volume.
Synonyms
  • Liquid dispenser: A general term for a device that dispenses liquid.
  • Dropper: A simpler device for transferring small amounts of liquid, but typically less precise than a laboratory pipet.
Related Phrases
  • Pipet filler (n): A device (often a rubber bulb or mechanical pump) attached to the top of a pipet to create the suction needed to draw up liquid.
  • Pipet tip (n): A disposable plastic tip attached to the end of certain pipets (like micropipettes) to hold the liquid, preventing contamination of the main instrument.
