VisionScan: a tool-less, non-destructive leak detection device for pharmaceutical blister packs. Using high resolution imaging technology, it offers pharmaceutical manufacturers a flexible, reliable, objective and cost saving alternative to destructive test methods.

Sepha has developed the world's first tool-less, vision-based leak detection machine for blister-packs. VisionScan has been designed to meet growing demand from pharmaceutical manufacturers for a low cost yet accurate and modern leak detection alternative to the blue dye test that can be integrated into their quality control systems.

VisionScan uses high resolution camera imaging technology to detect micron holes, channel leaks and weak seals in individual blister pockets in less than 60 seconds. Because it is tool-less, 21 CFR Part 11 compliant and capable of detecting defects down to 15 micron, it is ideal for both pharmaceutical manufacturers as well as contract and generic manufacturers where speed, accuracy and multiple product change over is required.

VisionScan is a non-contact and non-destructive test method which helps organizations to reduce waste by allowing good packs and their contents to be returned to the production line. All results are completely objective and displayed as a pass or fail removing any uncertainty of operator interpretation.


Since its launch at Interpack 2011, Sepha’s VisionScan has received an overwhelming response and has been demonstrated at exhibitions in USA, Europe, China and India. There are now several VisionScan machines operating in sites throughout North America, South America, Asia and Europe.
