Personal eyewash bottles contain Sperian® Saline solution. Personal eyewash devices are secondary response and intended to supplement, not replace, primary eyewash units. These products may also be used for continued irrigation when moving an injured person from a primary eyewash unit to medical care. The easy-open top is tamper-resistant, yet easily removed in an emergency. User-controlled volume delivers drops or an irrigating stream of solution, depending on the squeeze pressure applied to the bottle. FDA-grade polyethylene bottles feature lot numbers and expiration dates to ensure quality. Shelf life is 36 months.
