Introduction
Product Definition
The B15 Phenol Blue Test Reagent (10ml) is a semi-quantitative water quality test reagent that uses bromothymol blue as the color indicator, with product model B15. During testing, the reagent is dropped into a clear, transparent water sample, and the color change is used to quickly determine whether the target analyte in the water sample falls within the range of 6.0-7.6mg/L. The reagent features fast reaction and simple operation, making it suitable for rapid on-site screening of drinking water, aquaculture water, and industrial water.
Product Features
- Bromothymol blue color development system provides clear color changes for easy visual comparison.
- Rapid response: color development is completed in approximately 5 seconds.
- Dropper bottle packaging, approximately 200 drops per bottle; the dispensed volume per test can be controlled to meet semi-quantitative testing needs.
- Wide applicability, covering drinking water, aquaculture water, and industrial water.
- Compact and lightweight bottle, approximately 6*2cm and 8.9g, easy to carry and operate on site.
- The test water sample only needs to be clear and transparent, and can be tested without complex pretreatment.

Application Scenarios
The B15 Phenol Blue Test Reagent is mainly used for rapid water quality screening, especially suitable for routine drinking water testing, aquaculture water quality monitoring, and on-site testing of industrial water and circulating water systems. During use, the water sample should be clear and transparent, and the test solution temperature should be maintained within 0-60℃ to obtain stable color development results.
FAQ
Q: How should the B15 Phenol Blue Test Reagent be used?
A: Take an appropriate amount of clear, transparent water sample, add several drops of the test reagent, mix gently, observe the color development after approximately 5 seconds, and compare it with a color comparison reference for semi-quantitative interpretation.
Q: Will turbid water samples affect the test?
A: Yes. The test water sample must be clear and transparent. If the water sample is turbid, it should be filtered or left to settle until clear before testing to avoid interfering with color observation.
Q: How many tests can one bottle of reagent perform?
A: Each bottle provides approximately 200 drops. A standard dropper bottle delivers approximately 0.05ml per drop, and the actual number of tests depends on the number of drops used per test.
Q: What is the shelf life?
A: The shelf life is 1 year when unopened. After use, close the cap tightly and store it at 0-50℃ and ≤85%RH.
Q: What types of water samples can be tested?
A: It is suitable for clear and transparent water samples such as drinking water, aquaculture water, and industrial water.
