Product Overview
Methyl Purple pH Indicator Solution is a highly sensitive synthetic dye used extensively in laboratories for accurate pH measurements and acid-base titrations. This laboratory-grade indicator exhibits a distinct color transition from yellow in acidic conditions (pH 5.4), providing clear visual endpoints for precise analytical work. The solution is pre-diluted to optimal concentration, ensuring consistency and eliminating the need for additional preparation. Its stability and resistance to common laboratory contaminants make it ideal for routine and specialized applications where reliability is critical. The formulation adheres to stringent quality standards, ensuring minimal interference with test samples while delivering reproducible results. Whether used in educational settings or research environments, this indicator solution maintains its efficacy over extended periods when stored properly, making it a cost-effective choice for frequent laboratory use.
FAQs
1. What is the pH range for Methyl Purple indicator solution?
The color transition occurs between pH 4.8 (yellow) and 5.4 (violet), making it suitable for detecting weak acids and bases.
2. Can this indicator be used with organic solvents?
Methyl Purple is primarily water-soluble, but its compatibility with organic solvents depends on the specific solvent and concentration. Pre-testing is recommended.
3. What alternatives exist for similar pH ranges?
Bromocresol Green (pH 3.8–5.4) and Methyl Red (pH 4.4–6.2) are common alternatives with overlapping transition ranges.
4. How should this solution be stored for long-term use?
Store in a tightly sealed container at room temperature, away from direct sunlight and moisture to prevent degradation.
5. Is this indicator suitable for food or pharmaceutical testing?
While lab-grade, Methyl Purple is not certified for food or pharmaceutical applications. Use only for general laboratory purposes.
