Reagents should be stored at 25°C (room temperature) and away from heat, humidity, moisture, direct sunlight and cold conditions. The storage temperature should be kept as constant as possible, without large fluctuations in temperature. Reagents should not be kept refrigerated, unless specified otherwise in the kit instructions or packing literature for the reagents (for example, Coliscan Easygel®). Reagents should not be stored in work vehicles, utility rooms, pool and pump houses or other environments where conditions may be harsh. Exposure to such conditions will compromise the quality and stability of reagents and shorten reagent shelf lives.
