The Bitrex Fit Test Kit offers qualitative OSHA-complaint fit testing for
disposable and reusable dust and mist respirators. Bitrex creates an
unmistakable bitter taste that indicates break through in the respirator fit.
Bitrex has been found safer than saccharin tests while producing identical
results. Disposable glass ampules make pouring solution into nebulizers easier
and reduces the chance of contamination.
