Shelf Life Concerns
TEST STRIP SHELF LIFE
As with all perishables, test strips are sensitive to environmental influences and will last longer under controlled conditions.
To this end, we recommend:
- Storing test strips at a consistent temperature in the range of 36°–85°F (2°–29°C); storing test strips in a refrigerator can prolong the shelf life, but the bottle must be warmed to room temperature before opening to avoid condensation.
- Keeping them out of prolonged direct sunlight.
- Segregating test strips from containers of treatment chemicals.
- Replacing bottle lids immediately to reduce exposure to air and humidity.
Taylor formulates its test strips to remain effective for two years, the only exception being Salt test strips which last one year. As a general precaution, replace all test strips more than one year old, or at the beginning of a new testing season.
