#2 .75 oz DPD Reagent #2 Dropper Bottle R-0002

Taylor R-0002-A-24 DPD Reagent #2; 0.75 oz. Taylor formulates its reagents to remain effective for at least one year, with only very few exceptions (molybdenum indicator in liquid form is one; after four months old it should be tested against a standard periodically). As a general precaution, replace all reagents more than one year old, or at the beginning of a new testing season.

• Storage Recommendations:
• Storing reagents at a consistent temperature in the range if 36°–85°F (2°–29°C); extreme temperature fluctuation, say from a refrigerator to a hot car trunk, causes reagents to deteriorate.
• Keeping them out of prolonged direct sun
