Taylor Xpress Flex Device Water Testing System
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.
