The NanoMist ultrasonic spray nozzle is an ultrasonic atomizing nozzle with a very small spray width and ultra-low flow rate. It is based on ultrasonic atomizing nozzle technology and adopts a special liquid feeding device to achieve a smaller spray width and lower flow rate. 

Therefore, it is very suitable for coating on small area. The typical application of NanoMist ultrasonic spray nozzle is spray coating for drug eluted stent, especially small stents such as coronary stent and intracranial stent. Drugs such as rapamycin, paclitaxel, etc. are dissolved in an organic solvent to form a drug solution first, then the drug solution is atomized by NanoMist ultrasonic spray nozzle and uniformly spray it to the stent surface to form a uniform drug coating. The drug coating on the surface of the stent coated by NanoMist ultrasonic spray nozzle has no defects such as adhesion, pinholes and bubbles.

Features of Siansonic NanoMist ultrasonic spray nozzle:

• Very small spray width: about 1-2mm

• Capable of ultra-low flow rate: minimum flow rate can be around 0.005ml/min

• Ability to simultaneously spray up to 3 kinds of liquid with multi-liquid feeding devices 

• Uniformity > 95%

• Save raw materials: the utilization rate of raw materials is more than 85%, 4 times that of traditional air spray nozzle

• Small and uniform droplets

• Capable of intermittent or continuous spray

• Non-clogging ultrasonic spray nozzle

• Anti-corrosion ultrasonic spray nozzle
