VisionScan Max is a non-destructive, automated and tool-less blister pack leak test machine

The automatic blister leak tester has been developed to test the integrity of blister packs. The machine is capable of detecting defects in individual blister pockets, channel leaks and weak seals down to 7μm*.

VisionScan Max

The Sepha VisionScan Max is a smart alternative to the traditional blue dye leak test as the non-destructive method enables product to be returned to the production line. The machine is installed with an automated feed magazine for minimal operator involvement and offers pharmaceutical blister pack manufacturers the ability to automatically leak test full production batches with minimal operator input at speeds of up to 8 packs per minute (recipe dependent).

The Sepha VisionScan Max enables pharmaceutical manufacturers and packagers to meet the stringent quality control requirements of the industry while reducing waste and costs. The blister leak tester generates accurate, reliable pass/fail results and its tool-less design improves efficiency where multiple product changeovers are required.

  • Vacuum Deflection

    How does Vacuum Deflection testing work?

    To conduct a vacuum deflection test, a blister pack is placed inside a vacuum test chamber. The surface of the blister pack is scanned by a laser or vision system, to provide data points for subsequent deflection measurement. A vacuum is applied, and the pack surface is scanned a second time. The vacuum level is then reduced, and the pack is scanned once more.

    Deflection refers to the difference in the height of the foil of a cavity under vacuum compared to the first data point when the cavity was not under pressure. A cavity with a large hole will show no difference in the foil, as the hole allows the pressure inside the pocket to equalise to the applied vacuum inhibiting foil movement. If there is no hole present in the cavity, the lidding foil will move, and the second scan will show a large deflection as the cavity expands as a result of the applied vacuum.

    Cavities with small holes will initially expand because of the applied vacuum. The third scan is required to identify small holes. The variation in the average height at full vacuum and reduced vacuum is referred to as collapse. If the collapse is greater than normal, a small hole is present. This occurs as the air slowly escapes through a small defect, allowing the pressure inside the pocket to equalise with the applied vacuum.
