Moldex Bitrex Sensitivity Solution

The Moldex Bitrex Sensitivity Solution Ampoules are used during qualitative fit testing of tight-fitting respirators. These ampoules contain a denatonium benzoate (Bitrex) solution, a highly bitter-tasting substance used to determine whether a wearer can detect leakage during a respirator fit test.

They are essential for ensuring that respiratory protective equipment (RPE) forms an effective seal before workplace exposure.

What Is Bitrex?

Bitrex (denatonium benzoate) is one of the most bitter substances known. During a fit test:

• If the wearer detects a bitter taste while wearing a respirator,

• It indicates that the mask seal is not adequate.

This makes Bitrex a reliable solution for qualitative face fit testing procedures.
