HVLD Technology Pre-Filled Syringe Inspection

Pre-filled syringes are a widely used format for delivering pharmaceuticals, from small-molecule drugs to advanced biologics. Ensuring their sterility and integrity is critical for patient safety, yet traditional inspection methods like dye ingress or visual checks often fall short due to high false-negative risks. MicroCurrent High Voltage Leak Detection (HVLD) offers a deterministic, non-invasive solution that addresses these challenges. By applying dynamic multi-zone inspection and specialized probes, HVLD can detect breaches at critical interfaces such as the plunger-barrel seal. This technology identifies microchannel defects caused by debris, ensuring robust and reliable integrity testing across all product fills.
