FT31 – Bitter Face Fit Testing Sensitivity Solution
If you need help with your purchase or
have any questions call our consultants
The FT30 Face Fit testing kit uses denatonium benzoate to produce a very bitter taste.
The choice between the bitter and sweet test kit is a personal one, however a small percentage of the population are unable to detect saccharin (used in the Sweet Test Solution) in which case the bitter test must be used.
