Overview
- We have responded with an expansive selection of professionally manufactured specialty test kits for every job. With industry-leading innovation and quality built into every kit, there is never a need to own multiple test kits or reagents that you won’t use. You’ll never have to choose between accuracy and convenience-they’re always packaged together, in every water test kit.

Storage

All reagents have a shelf life, whether they are liquids, powders, crystals, tablets, or test-strip pads. If kept dry, powders and crystals are very stable; acids are also long lived. Date of manufacture is not the controlling factor when it comes to shelf life-storage conditions are more important. As with all perishables, reagents are sensitive to environmental influences and will last longer under controlled conditions.

To this end, we recommend:
• 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 sunlight. (Note: their brown plastic bottles help protect very light-sensitive reagents.)
• Segregating reagents from containers of treatment chemicals.
• Replacing caps immediately and tightening them carefully so that exposure to air and humidity is limited.
• Avoiding switching bottle caps, placing bottle caps on soiled surfaces, repouring reagents into contaminated containers, or touching test strip pads.

We formulate 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.
