A variable volume micropipette is a laboratory equipment used for transferring a precise volume of liquid. It is a type of micropipette that allows the user to adjust and dispense a specific volume of liquid, typically ranging from 0.5 μL to 10 mL. The volume is adjustable by a mechanical or electronic mechanism and can be set to a desired value for each use.

Variable volume micropipettes are commonly used in laboratory settings for tasks such as adding a specific amount of reagent to a solution, dispensing a varying volume of a sample, or performing serial dilutions. They are widely used in molecular biology, genetics, and other scientific fields that require precise and accurate liquid handling.
