Instant hand sanitizer refill is designed for use with PURELL NXT Maximum Capacity Sanitizer Dispensers. Alcohol-based sanitizer kills 99.99 percent of most common germs that may cause illness and works in as little as 15 seconds. No water or towels needed. Unique moisturizing system leaves hands feeling soft (gentler to the hands than most soaps). Collapsible bag refill makes the best use of space inside the dispenser. Each refill includes a fresh dispensing valve.
