    For optimal usage, every pipette supplier offers a broad range of different capacities, commonly including 2, 10, 20, 100, 200, and 1000 μL capacity pipettes. [citation needed] A small volume range of a pipette like 10–100 μL results in a much higher accuracy than a broad range from 0.1–1,000 μL per pipette.

It is used to accurately measure and transfer a volume of liquid from one container to another. [1] It is made from plastic or glass tubes and has a tapered tip. Along ...

  6. Positive displacement pipette - Wikipedia

    en.wikipedia.org/wiki/Positive_displacement_pipette

    Positive displacement pipettes are a type of pipette that operates via piston-driven displacement. [1] [2] Unlike an air displacement pipette, which dispenses liquid using an air cushion in the pipette tip, the piston in a positive displacement pipette makes direct contact with the sample, allowing the aspiration force to remain constant. [3]
