Seidenader Maschinenbau of Germany has introduced a high voltage inspection module for vials and pre-filled syringes.
The company's new approach to leak detection syringes is a precise handling system that presents the containers at an angle of 90-110° to a minimum of four high voltage electrodes, which detect cracks that fully penetrate the glass, while ignoring surface scratches.
The high voltage inspection module is integrated in the Seidenader VI and MS families of inspection machines allowing camera inspection before high voltage inspection. Only products that pass all camera inspections undergo a final high voltage check for cracks. Seidenader says the module can be quickly dismantled and easily cleaned for changeover.
Extensive comparative testing based on validation samples from production has shown a clear advantage in finding cracks in sidewall, bottom and closure zones of vials, the company says.
