The ST-100 Model is our flagship model and is the pinnacle of portability and functionality! It has an LCD display and countdown timer with alarm sound when rinse cycle is completed. This will leave plenty of time for the user to pump soap, lather up, and finish washing and rinsing under the water for the remaining 20 second minimum. The user should then turn off the water shielding their clean hands with the paper towel they had just used to dry their hands. This leads to the user not touching anything except sterile utensils and equipment after they have washed their hands.
Operation begins with the user turning on the water flow on the sink valves.
