A pipette is a laboratory device for precisely measuring volumes of liquid between 1-25ml. In this video Justine Siew and Glorianna Tarlton describe how to use a pipette with pro-tips and warnings to help you use a pipette like a pro. They also describe how pipettes were used to help scientists study tiny "bacterial swords" in bacteria that can only grown in tiny amounts of oxygen!
