Abstract
A displacement device for displacing a displacement volume is disclosed. The device has a first fluid space and a second fluid space. A first piston is arranged in a movable manner within the first fluid space. The first fluid space is connectable to a pipetting device. The first piston is actuatable by an actuation volume of air or of liquid provided by the pipetting device. A second piston is arranged in a movable manner within the second fluid space. The second piston is constructed to displace a displacement volume of a fluid located within the second fluid space when the second piston is actuated. The second piston is actuated in dependence on the first piston that is actuated by the actuation volume. The actuation volume is different from the displacement volume, and a pipetting system has a displacement device and a method of displacing a displacement volume.
