Positioning system and method for a liquid transfer device

摘要

Disclosed is the positioning of at least one of a well plate (10) and a liquid transfer appliance (20A) relative to each other. The liquid transfer appliance (20A) and the well plate (10) are moved towards each other and a current is detected caused upon contact between the liquid transfer appliance (20A) and a first electrically conductive element (30) of the well plate (10). The position of the well plate (10) relative to the liquid transfer appliance (20A) is determined at the point of time of contact, and the determined position is used as a reference position for further positioning at least one of the well plate (10) and the liquid transfer appliance (20A).
