Product Overview

Bromothymol blue indicator solution is a highly reliable pH-sensitive dye widely used in laboratories for titrations, environmental testing, and biochemical assays. This analytical-grade solution exhibits a sharp color transition from yellow (acidic, pH 7.6), with a distinct green intermediate at neutral pH (7.0), ensuring precise endpoint detection in experiments. The solution is pre-diluted for immediate use, eliminating the need for preparation and reducing procedural errors. Its stability under standard lab conditions makes it ideal for long-term storage without degradation. The non-toxic, water-soluble formulation ensures compatibility with aqueous systems, while its high purity minimizes interference in sensitive applications. Whether for routine pH monitoring or critical research, this indicator delivers consistent performance with clear, unambiguous color changes. The 125 ml packaging provides sufficient volume for repeated use while maintaining cost efficiency for educational and professional settings.

FAQs

1. What is the pH range for bromothymol blue indicator solution?

Bromothymol blue transitions from yellow to blue between pH 6.0 and 7.6, with green appearing around neutral pH (7.0).

2. Can this indicator be used in non-aqueous solvents?

It is primarily designed for aqueous solutions. For non-aqueous systems, compatibility testing is recommended as color changes may vary.

3. 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.

4. Is this indicator solution light-sensitive?

Prolonged exposure to light may cause gradual fading. Store in amber or opaque bottles when not in use.

5. What alternatives exist for pH ranges outside 6.0-7.6?

For lower pH, methyl orange (3.1-4.4) or thymol blue (1.2-2.8) can be used. For higher pH, phenolphthalein (8.3-10.0) is suitable.
