The Allegro RK-2041-11K Bitter Sensitivity Solution Ampules provide the required solution used during the qualitative sensitivity screening step of an OSHA-compliant respirator fit test. Formulated with denatonium benzoate, the solution produces a distinct bitter taste that allows users to verify they can detect the agent before conducting the actual fit test. Each glass ampule contains pre-measured liquid to simplify loading into the nebulizer and reduce the risk of contamination. Packaged in convenient boxes of six, these ampules ensure consistent, accurate preparation for routine respirator fit testing in industrial, healthcare, and field-service environments.
