MSK-USP-04C Ultrasonic Spray Pyrolysis Coater/Glue Sprayer uses a stepper motor and a microprocessor to control the volumetric pump to ensure accurate transmission of solutions through the infusion set and the continuity of ultrasonic spray process. An ultrasonic atomizer is used to prepare a thin micro-nano coating, and a stepper motor is used to control the atomizer to move in the X-axis and Y-axis directions, and the moving speed can be adjusted within a certain range to ensure the uniformity of coating on the substrate surface.
