Unique nozzle design provides a preserved, buffered, saline solution superior to tap water for emergency eye care. Integral fluid reservoir captures waste fluid to eradicate spill hazards and simplifies fluid disposal. Expiration date is rendered on an activation straps and the cartridge lasts at least four times longer than other primary, self-contained eyewashes.
