Product Overview

Congo Red Indicator Solution by Lancer is a ready-to-use, lab-grade pH indicator widely employed in acid-base titrations and biological staining techniques. With its clear red-to-blue color transition in response to pH changes, it serves as a reliable visual aid in both chemistry and biology labs.

For Academic Use:
In school and college chemistry labs, Congo Red helps students identify endpoint shifts during acid-base titration. Its distinct pH range makes it ideal for hands-on learning and conceptual clarity during practical sessions.

For Industrial Use:
Used in textile and dye research, Congo Red also finds utility in protein assays, waste water testing, and paper pH testing. The solution provides fast color change responses, making it suitable for high-throughput lab environments.

For Institutional Use:
Universities and biological research labs use Congo Red for microscopic staining of amyloid proteins and cellulose fibers. Its dual utility in chemistry and biology makes it a staple in multidisciplinary research institutions.

FAQs

1. What is the pH range of the Congo Red indicator?

It changes from red to blue between pH 3.0 and 5.0, making it ideal for detecting strong acid environments.

2. Is it safe to use with biological specimens?

Yes, Congo Red is often used for staining amyloid in histopathology and cellulose in plant tissues.

3. Can it be used as a food dye?

No, this laboratory-grade solution is not food-safe and is strictly for educational and scientific use.

4. How should the solution be stored?

Keep in a cool, dry place, away from direct sunlight. Close the cap tightly after each use to prevent degradation.

5. Is it compatible with all types of titration?

It is suitable for acid titrations but not ideal for neutral or weak acid-weak base systems. Use alternatives like phenolphthalein for broader applications.
