Indicators and Dyes

Holland Moran is proud to offer the most comprehensive line of indicators and Dyes - many of which are available in both solutions and powdered forms.

Indicators are related to stains and dyes. These reagents indicate the presence, absence, or concentration of another substance by means of a characteristic color change. Indicators are commonly used to determine pH or to detect the presence of metal ions.
