A good indicator turns a color change into a clear answer. Thermal Scientific carries pH indicators and chemical indicators from Ricca Chemical, including universal indicator for pH 2 to 10, DPD indicator solution for chlorine testing, and diphenylcarbazone-xylene cyanol for chloride titrations. Choose by method, color change, and container size.
For titration indicators such as starch and methyl red, see our indicators in Reagents & Titrants. Browse stains and dyes, or the full stains, dyes, and indicators selection.
We carry universal indicator, DPD indicator solution, and diphenylcarbazone-xylene cyanol, among others, from Ricca Chemical.
Universal indicator is a mixture that changes color across a wide pH range, from about pH 2 to 10, giving a quick estimate of acidity or alkalinity.
See our indicators in Reagents & Titrants, which carry a broader selection for titration work.
