    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.

    Abstract: The invention relates to a device (20), comprising: a liquid container (21) for containing a liquid; a capillary-stop valve (22) that is in medium through flow connection with said liquid container (21) for stopping said liquid in said container from flowing out of said container via said capillary-stop valve (22); a first electrode (7) being arranged such that in use said first electrode is in contact with said liquid in said liquid container; a second electrode (2) that is spaced apart from said capillary-stop valve by an electrically insulating medium gap (24), and a voltage source (V) connected to said first and second electrode which is activatable for applying an electric potential difference at the first and second electrode such that the liquid in the liquid container is attracted in the direction of said second electrode so as to allow the liquid to overcome the stopping effect of the capillary-stop valve for discharging liquid from said liquid container via said capillary-stop valve. The invention also relates to a method for activating a capillary-stop valve of a device.

    Abstract: The invention relates to a method for manufacturing and testing microfluidic chips having at least one capillary for through-flow of a fluid. The method comprises the following steps: - providing a starting material; - forming at least one shared capillary in the starting material; - arranging a plurality of functional elements in or over the shared capillary, thus forming a plurality of chips; - testing the chips by supplying a test fluid to the shared capillary; and - dividing the starting material into separate chips. The invention further relates to a device for testing microfluidic chips having at least one capillary for through-flow of a fluid. This device comprises a material holder for holding a starting material in a fixed position during testing, and an inlet connector for connecting a shared capillary formed in the starting material to a test fluid supply.
