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.
