A fixed-volume micropipette is a laboratory equipment used for transferring a precise and fixed volume of liquid. It is a type of micropipette that is designed to dispense a specific volume of liquid each time it is used, typically ranging from 0.5 μL to 10 mL.
The volume is set and fixed by a mechanical or electronic mechanism and cannot be adjusted. Fixed-volume micropipettes are commonly used in laboratory settings for tasks such as adding a specific amount of reagent to a solution, dispensing an exact 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.
