A-dec's waterline maintenance solution is designed to reduce the risk of cross contamination. The 500 Series water bottle is designed with the pick up tube inside the bottle, reducing the possibility of contamination during refill. The 500 water bottle also allows the addition of treatment chemicals, such as ICX. A-dec's control block features a technology that allows water to continuously flow throughout the dental unit, helping avoid issues caused by stagnant water caught inside tools.
