Product Overview
Brilliant Green Indicator (95% dye content) is a synthetic triarylmethane dye widely used as a pH indicator and biological stain in laboratory settings. This high-purity reagent exhibits a distinct color transition from yellow to green to blue across the pH range of 0.0-2.6, making it invaluable for acid-base titrations and microbial differentiation tests. The powdered form ensures easy dissolution in aqueous and alcoholic solutions, providing consistent performance in various analytical protocols. Its stable chemical structure and minimal impurity profile (≤5% inert components) guarantee reliable results in sensitive applications. The reagent is particularly effective in Gram staining procedures where it serves as a counterstain, and in environmental testing for pH monitoring. Each batch undergoes rigorous quality control to maintain the specified 95% dye content, ensuring reproducibility in research and industrial applications. The product’s long shelf life when stored properly makes it a cost-effective choice for laboratories requiring frequent pH indicator use.
FAQs
1. What is the exact pH range where Brilliant Green Indicator changes color?
The color transition occurs between pH 0.0 (yellow) to pH 2.6 (blue), with green appearing at intermediate pH values around 1.0-2.0.
2. Can this indicator be used for Gram staining procedures?
Yes, Brilliant Green is commonly employed as a counterstain in modified Gram staining protocols, particularly for differentiating bacterial species.
3. What solvents work best for preparing Brilliant Green solutions?
The dye dissolves readily in water and ethanol. For most applications, a 1% aqueous solution is typically prepared.
4. How should I store this product to maintain its stability?
Store in a tightly sealed container, protected from light and moisture, at room temperature (15-30°C) for optimal shelf life.
5. Is this the same as Malachite Green indicator?
No, while chemically similar, Brilliant Green has a different substitution pattern and slightly different pH transition range compared to Malachite Green.
