The M-Zone MicroDispenser™ combines touch-free dispensing with no-hassle installation and easy change out of bottles. The compact, gravity fed unit has no tubes and a simple pump action - which means easier bottle insertion and more efficient battery use. A bubble spout screws onto the 500 ml bottle. The 2ml capacity green spout works with standard soaps and sanitizers and the 1 ml capacity blue spout for sterile IPA. Once the spout is attached the inverted bottle snaps into the well of the dispenser. When the electronic beam is broken by a hand passing under the unit, the bubble on the spout depresses to dispense the soap or lotion into the palm.
