Abstract: The invention relates to a device for measuring a volume of a liquid, said device comprising: - a receptacle for receiving said liquid, said receptacle comprising an inlet opening and an outlet opening, and - a capillary channel having capillary action, which capillary channel has a predetermined internal transverse cross-section, wherein an inlet opening of the capillary channel at an first end thereof is in liquid through flow connection with the outlet opening of the receptacle and wherein the other, second end of the capillary channel comprises an opening; wherein: - the inlet opening of the receptacle has a larger transverse cross-section than the inlet opening of said capillary channel, and - a length of a liquid slug in the capillary channel is a measure for said volume. The invention further relates to a method for measuring a volume of a liquid using such a device, a method for calibrating a liquid dispensing system using such a device, a calibrating system for calibrating a liquid dispensing system using such a device and a support for supporting a plurality of such devices.
