Denatonium Benzoate creates an unmistakable bitter taste that indicates a breakthrough in the respirator fit. Denatonium Benzoate has been found safer than Sweet (Saccharin) fit tests while producing identical results. Disposable glass ampules make pouring solution into nebulizers easier and reduces the chance of contamination.
