The Pure Flow® 1000 delivers unequaled eyewash safety, reliability and value. The patented eye wash system delivers purified, contaminant-free and physiologically correct saline solution from factory-sealed cartridges. Available with or without two solution cartridges, Pure Flow® 1000 does not require costly plumbing because it features a fluid pressure balancing system that provides a constant fluid flow rate and stream height for the entire 15-minute flushing period required by ANSI Z358.1-2004. Pure Flow® 1000 factory-sealed cartridges last up to 24 months, at least four times longer than other primary self-contained eyewash devices. Shelf life determined by date of manufacture. Always check product expiration date. Order replacement cartridges or a steel eye wash cart to hold and move the Pure Flow®
