The VisionScan non-destructive leak tester is a new alternative to Blue Dye tests, which destroy good packages during testing. Using the latest in camera imaging technology, the VisionScan offers pharmaceutical manufactureres a flexible, reliable, objective, and cost saving alternative to destructive tests. With typical blue dye tests, all tested packages, good or bad, are destroyed. The VisionScan does not harm the blister package so good packages can be put back into the line. Blue dye tests also rely on a visual inspection by the operator so can be subjective. The VisionScan produces a quantifiable, objective result and shows you exactly which cavity has a leak.
