Product Overview
Bromothymol Blue 0.1% w/v in methanol is a highly sensitive pH indicator solution designed for precise laboratory applications. This lab-grade reagent transitions from yellow to blue across the pH range of 6.0 to 7.6, making it ideal for detecting subtle pH variations in aqueous solutions. The methanol-based formulation ensures stability and consistent performance, eliminating precipitation issues common with water-based indicators. Its low concentration (0.1%) provides optimal color intensity without overpowering samples, while the solvent choice enhances solubility in both aqueous and organic systems. The solution is prepared using analytical-grade bromothymol blue dye dissolved in high-purity methanol, ensuring minimal interference in sensitive assays. Its rapid response time and reversible color change allow for real-time pH monitoring during titrations or environmental testing. The 125ml packaging offers convenient handling while maintaining solution integrity through proper sealing. This formulation meets stringent laboratory standards for accuracy and reproducibility in qualitative and semi-quantitative pH determinations.
FAQs
1.
What is the exact pH range where Bromothymol Blue shows color change?
The color transition occurs between pH 6.0 (yellow) and 7.6 (blue), with a green intermediate at neutral pH. 2.
Can this solution be used with non-aqueous solvents?
The methanol base provides compatibility with many organic solvents, though color intensity may vary. 3.
What’s the shelf life when stored properly?
When kept in tightly sealed original packaging away from light, the solution remains stable for 24 months. 4.
Is this formulation suitable for microbiological media?
Yes, but sterility should be verified as this is not a sterile preparation. 5.
How does methanol concentration affect the indicator’s performance?
The 0.1% concentration in methanol balances solubility and sensitivity without altering the indicator’s pH range.
