The industry standard of blue-dye testing the seal integrity of blisterpacks is not as accurate as Sepha’s proprietary Blisterscan technology.
Dr Dorian Dixon, of the University of Ulster, compared the ability of Blisterscan and the blue dye test to detect defective pockets in blister packs.
The most widely used industry method for testing blister pack integrity is blue dye testing. The Sepha Blisterscan is a dry, non-destructive technique which uses a laser to measure changes in the pack profile which result from applying a vacuum.
In some cases, the difference in accuracy between the two methods in finding a defective blister pack could be as much as 10%, with consequent impacts on quality control and cost reduction, it is claimed.
