LaMotte 7037-G pH Indicator

The 7037-G is specifically formulated as a Phenol Red indicator for pH testing. While it is designed for use with standard LaMotte colorimetric test kits, you should verify that your specific test kit requires Phenol Red for pH analysis before purchasing.

While the exact number depends on the specific test kit you are using, a 30ml bottle typically provides enough reagent for approximately 60 to 100 individual tests, assuming a standard drop count per test.

Yes, like most chemical reagents, this product has a shelf life. For the most accurate readings, it is best to use the reagent within one year of opening and store it in a cool, dark place away from direct sunlight.

This reagent is specifically calibrated for the pH ranges typically found in swimming pools and spas, usually between 6.8 and 8.2. It is not recommended for testing drinking water or aquariums, which often require different sensitivity ranges.

Keep the cap tightly closed when not in use and store the bottle in a cool, dry environment, such as a pool equipment cabinet. Avoid exposing the reagent to extreme temperatures or direct sunlight, as these can degrade the chemical composition and lead to inaccurate test results.
