Device and system for a leak test of a container and method for same

A device for a leak test of a container comprising:

• a first electrode;
• a second electrode that is arranged at a distance from the first electrode so that a space for the arrangement of the container is provided between the electrodes;
• a power supply that is adapted to apply a voltage between the first electrode and the second electrode;
• and
• at least one analysis unit that is adapted to analyze a current progression that is adopted on a presence of the container to be tested for its leak tightness between the first electrode and the second electrode to detect a leak tight or leaking container on the basis thereof,
• wherein
• the power supply is adapted to apply a DC voltage between the first electrode and the second electrode that is in the range from 500 V to 50 kV so that a static inhomogeneous electrical field is formed between the first and second electrodes while applying the DC voltage, and
• a device for rotating the container about an axis is provided between the first electrode and the second electrode in the space for the arrangement of the container so that the at least one analysis unit is able to analyze the current progression during a rotation of the container, during at least one rotation of the container, and wherein
• the first and second electrodes are field electrodes for generating the electrical field between the electrodes, wherein the electrodes are arranged so that when a container passes through the electrical field, a change of current flow is measured between the two electrodes with the analysis unit, and wherein the current flow is indicative for a leak of the container.
