High Voltage Leak Detection (HVLD) technology provides a reliable way to inspect liquid-filled pharmaceutical containers for defects. The method applies a controlled electrical charge across the container, allowing the system to detect flaws such as cracks, pinholes, or faulty seals. HVLD works particularly well with injectable drug packaging including glass vials, ampoules, and prefilled syringes. As a deterministic technique recognized within USP , it delivers highly sensitive detection without damaging the product. By identifying even minor container defects, HVLD helps pharmaceutical manufacturers maintain sterility, comply with regulatory requirements, and protect patient safety.
