VisionScan 3D is a non-destructive, tool-less leak test for blisters including all foil types. The Sepha VisionScan 3D is a blister leak test solution that takes non-destructive leak testing to a new level. The next generation machine is built around our new 3D measurement technique to test the integrity of pharmaceutical blister packs. The 3D technology is used in combination with differential pressure and vacuum and enables the machine to detect leaks in individual blister pockets as low as 5μm (pack and material dependent). The new technology can be applied to all foil types, matt or gloss. Different text patterns can be tested with one test method, making it ideal for production lines with multiple language print variations. The system is designed to allow for easy calibration, quick set up times and a streamlined validation process across different foil types. The system requires no tooling, while the large test area of 297x210mm enables multiple blister packs to be tested simultaneously. It is ideal for operations where multiple product changes are required. The machine utilizes the principle of vacuum deflection according to ASTM standard test method F3169-16. Compared with previous models (including the Blister Scan and VisionScan) this test principle has not changed. It is the new measurement technique, the 3D sensor that now creates the profile. The VisionScan 3D offers pharmaceutical manufacturers a flexible, reliable, deterministic and cost saving alternative to a destructive leak test for blisters. The method does not affect the integrity of the blister pack, allowing packs that have passed the test to be returned onto the production line.
