The Allegro RK-2041-12K Bitter Test Solution Ampules contain the denatonium benzoate agent used during the qualitative respirator fit test challenge step, where the wearer must not detect the bitter taste while under respirator seal. These pre-measured glass ampules simplify loading into the nebulizer and support consistent aerosolization for OSHA-compliant fit testing. Designed for use with the Allegro 2041 Bitter Fit Test Kit, the solution provides a reliable challenge indicator to confirm whether a respirator achieves an adequate seal. Packaged in convenient boxes of six, these ampules are ideal for routine fit testing programs in industrial, healthcare, and field-service environments.
