Introduction
Product Definition
The B03 Phenolphthalein Test Reagent (10ml) is a semi-quantitative water quality test reagent that uses phenolphthalein indicator for rapid pH testing. By observing whether the water sample develops color and how deep the color is after adding the reagent, the pH of the water sample can be quickly determined to be in the 8.2-10 range. It is suitable for on-site testing of clear, transparent water samples such as drinking water, swimming pool water, and aquaculture water.
Product Features
- Simple operation: No instrument required; directly add the reagent drops and observe the color change.
- Rapid color development: Reaction time approx. 5s; results can be observed immediately.
- Semi-quantitative assessment: The shade of pink to red quickly indicates the pH range of the water sample.
- Wide applicability: Suitable for pH screening of drinking water, swimming pool water, aquaculture water, and other water qualities.
- Portable and easy to use: Compact dropper bottle, approx. 200 drops per bottle, suitable for daily carrying and frequent testing.
- Strong environmental adaptability: Sample temperature range 0-60°C; operating ambient temperature 0-50°C.

FAQ
Q: How are results interpreted with the B03 Phenolphthalein Test Reagent?
A: Take a clear, transparent water sample, add an appropriate amount of B03 reagent, and observe the solution color after about 5 seconds. If the solution is colorless, the pH is below approximately 8.2; if it turns pink to red, the water sample pH is in the 8.2-10 range, and the deeper the color, the closer the pH is to 10.
Q: Can this product test water samples with a pH below 8.2?
A: When the water sample pH is below 8.2, the reagent remains essentially colorless, indicating that the sample is outside the alkaline detection range of this product. For lower pH values, please use a test product with a corresponding measurement range.
Q: Can it be used if the water sample is turbid or colored?
A: It is not recommended. The water sample must be clear and transparent. Turbid or colored water samples can interfere with color development observation and affect the accuracy of the results.
Q: How many tests can one bottle provide?
A: Each bottle contains approximately 200 drops. The actual number of tests depends on the number of drops used per test; the fewer drops used, the more tests can be performed.
Q: How should the B03 Phenolphthalein Test Reagent be stored?
A: The shelf life is 1 year. It is recommended to store the reagent tightly sealed, protected from light and moisture, away from direct sunlight and high temperatures, and to use it as soon as possible after opening.
