With ultrasonic nozzle, the spray solution is homogenised, drop size effectively controlled (nozzle frequency influences drop size), and micro spray volumes can be dispensed, ensuring uniformity in composition and structure and more precision of the resultant thin films and patterns. Material wastage is kept to a minimum and there is less risk to the operator of the equipment.

The MultiCoater’s ultrasonic spray coater can be equipped with a heated platform for the substrate, e.g. a hot plate. More than one independently controlled syringes (coating solution container) can be used to handle different materials, essential for multilayer fabrication or creating different thin films on different parts of a substrate - if necessary one of the syringes can contain a cleaning liquid, e.g distilled water, to avoid contamination. The ultrasonic spray coater can be combined with a dip coater, in this situation being kept stationary while the dip coating module  is mobile
