Ultrasonic atomizer nozzles produce fine droplets for uniform, controlled coatings on medical and other sensitive and/or small devices. The nozzle spray velocity is low, making it useful for applying thin layers of valuable chemistries with minimal overspray. Ultrasonic nozzles offer several key advantages in stent coating as well as other precision medical device coating and manufacturing applications. Sonaer nozzles provide excellent repeatability in spray velocity and droplet size, in addition to large reductions in coating material consumption.
