Henderson Biomedical are able to supply the Ink Test PRO by Hawo. This consists of a box of 30 disposable sachets, each one filled with blue dye. Users take one sachet and seal it inside a paper/film pouch. Then the user bursts the sachet and allows the liquid to run down all four sides of the pouch. Any defections or gaps in the seal become instantly visible.
The Ink Test PRO is clean and easy-to-use. It avoids hands and work spaces becoming messy with the dye. You can see how it work by watching this video.
