Dye leak detection method

摘要: An improved method for testing the integrity of containers and closures same is disclosed which simple, easy to perform, possesses a high degree sensitivity. The comprises immersing container (whose walls are substantially transparent in liquid stored) into solution dye under conditions will favor passage through any leaks present or closure liquid. then placed path laser beam emitting wavelength approximates fluorescent excitation frequency dye. If color transmitted that characteristic fluorescing dye, leak system indicated.
