Suitable for leak testing for prefilled syringes; focuses on identifying micro-holes and cracks in the barrel, especially around joint lines and the plunger area. This leak tester is also suitable for prefilled syringes and other injectable containers that require high-sensitivity CCI (Container Closure Integrity) evaluation. The testing process ensures thorough inspection of both the sealing zones and the syringe body without compromising the contents or packaging.
Prefilled syringes are first aligned onto the feed screw via a dedicated transport track. A rotary mechanism then positions each syringe accurately for inspection across multiple stations. Each point uses high-voltage discharge technology to evaluate specific sections of the syringe, such as the body, flange, and tip, according to user-defined parameters. Once inspection is complete, a rejection wheel automatically separates defective syringes from those that pass the leak test.
High Voltage Leak Detection (HVLD) operates by measuring conductivity changes when a defect is present. If a leak exists, resistance in the testing path drops, allowing a higher current to flow. This current is then evaluated against a defined threshold to determine if the syringe is compromised. The entire process is deterministic and non-destructive, making it ideal for pharmaceutical packaging integrity.
Integrating an HVLD-based tester in the production line ensures that each prefilled syringe meets safety and compliance requirements. It eliminates the risks associated with manual inspection, reduces waste from destructive testing, and minimizes the chances of product recalls. Ultimately, it helps pharmaceutical companies deliver safe, precisely dosed medications to patients.
Yes, the testing system uses low-energy pulses and brief exposure times, keeping qualified syringes insulated during inspection. Since the voltage does not come into direct contact with the liquid and has no chemical or physical impact, the process preserves both container integrity and product safety.
