Product Overview
Congo Red Indicator Solution is a high-quality, lab-grade reagent designed for accurate pH detection in chemical and biological applications. This indicator-grade solution transitions sharply between pH 3.0 (blue) and 5.0 (red), making it ideal for titrations, microbial studies, and staining procedures. Formulated with precision, it ensures consistent color changes for reliable results in experimental setups. The solution is stable under standard lab conditions, resisting degradation from light or temperature fluctuations. Its water-soluble nature allows seamless integration into aqueous systems without precipitation or turbidity. Whether used in qualitative analysis or quantitative assays, this Congo Red solution delivers repeatable performance, minimizing variability in research and educational experiments. The 125 ml pack size provides sufficient volume for multiple tests while maintaining freshness. Compatible with most glassware and plastic labware, it avoids reactions with common solvents, ensuring purity throughout applications.
FAQs
1. What is the pH range for Congo Red Indicator Solution?
The solution changes color between pH 3.0 (blue) and 5.0 (red), making it effective for detecting acidic conditions.
2. Can this solution be used for biological staining?
Yes, Congo Red is commonly employed in staining cellulose materials and certain microbial structures due to its affinity for polysaccharides.
3. How should this indicator solution be stored for long-term use?
Store in a cool, dark place in its original tightly sealed container to prevent evaporation and light-induced degradation.
4. Is this solution compatible with organic solvents?
It is primarily water-soluble; compatibility with organic solvents depends on the specific solvent and application—test prior to use.
5. What alternatives exist for pH indicators in this range?
Methyl Orange (pH 3.1–4.4) or Bromophenol Blue (pH 3.0–4.6) can serve as alternatives, though their color transitions differ.
