A pipette is used to very accurately displace a volume if liquid. Pipettes can suspend volumes from 1 µl (= 0,001 ml) accurately. They are therefore irreplaceable and of crucial importance in a lab.

Vacuum
In order to displace or move microbes, or just simply suspend a very small volume of liquid, you need a specialized device: the pipette. This device is used in every microbiology and medical laboratory. By pressing on the button on the top with your thumb, a vacuum is created inside the device, through which the liquid is sucked up into the so-called pipette tip. On the pipette you can adjust the exact volume (µl, one thousandth of a milliliters) of liquid you want to suck up. Once in the pipette tip, the liquid with microbes for example, can be easily displaced.
1 tot 1000 microliters
The volume of liquid that can be displaced is dependent on the pipette as well as the pipette tip. Pipettes that pipet 1 to 1000 µl are called micropipettes. Pipettes that work with larger volumes of liquid are called macropipettes. Pipette tips are also available in variable sizes, and will have a maximum volume of liquid it can take up. This is why it is important to select the correct pipette and pipette tips for a specific task.
