Product Overview
Brilliant green indicator powder is a high-purity, laboratory-grade dye widely used for pH detection and microbiological applications. This synthetic dye belongs to the triarylmethane family and exhibits a vibrant green color in neutral to alkaline solutions, transitioning to yellow in acidic environments, making it an excellent visual indicator. Its fine powder form ensures easy dissolution in aqueous solutions, providing consistent and reliable results in various lab procedures. The compound is chemically stable under standard conditions, ensuring long shelf life when stored properly. Its high sensitivity to pH changes makes it particularly valuable in titration experiments and bacterial staining protocols. The powder form allows for precise measurement and custom concentration preparation, catering to different experimental requirements. As a non-toxic, water-soluble dye, it maintains compatibility with most laboratory reagents and equipment. The product undergoes rigorous quality control to ensure batch-to-batch consistency in color intensity and chemical purity.
FAQs
1. What is the solubility of brilliant green indicator powder?
Brilliant green indicator powder is highly soluble in water and ethanol, typically dissolving completely at concentrations up to 1% w/v in aqueous solutions.
2. Can this indicator be used for Gram staining procedures?
While primarily used as a pH indicator, brilliant green can serve as a counterstain in modified Gram staining protocols due to its affinity for bacterial cell walls.
3. What is the pH range for color transition in this indicator?
The color transition occurs between pH 0.0 (yellow) to pH 2.6 (blue-green), with the most visible change happening in strongly acidic conditions.
4. How should this powder be stored for maximum shelf life?
Store in a tightly sealed container at room temperature, protected from light and moisture to maintain stability and prevent degradation.
5. Is this product compatible with automatic dispensers?
The fine powder consistency makes it suitable for most laboratory dispensers, though pre-dissolution may be required for liquid handling systems.
