MSK-SP-01A 40kHz 130W Ultrasonic Spray Nozzles with Dual Titanium Alloy Heads and Power Controller for DIY Spray Pyrolysis
The MSK-SP-01A is engineered to facilitate precise spray pyrolysis coating in material research laboratories by converting liquid solutions into fine aerosol droplets. This ultrasonic spray system employs a 40 kHz piezoelectric transducer to generate ultrasonic vibrations that atomize liquids into droplets typically smaller than 25 microns, enabling uniform thin film deposition.
The unit includes a power controller capable of delivering up to 130 W of adjustable ultrasonic output power, ensuring optimal atomization efficiency. Two titanium alloy (Ti-6Al-4V) spray nozzles are provided: a cylindrical nozzle producing a narrow spray pattern approximately 2 cm in diameter, and a cone nozzle generating a wider spray pattern around 4 cm in diameter. Both nozzles connect via a KF25 quick clamp adaptor, facilitating integration with standard vacuum or spray systems.
Key Features
- Ultrasonic frequency fixed at 40 kHz for consistent atomization.
- Adjustable ultrasonic power output from 0 to 130 W with three selectable levels.
- Two titanium alloy nozzles: cylindrical (narrow spray) and cone (wide spray) types included.
- KF25 quick clamp adaptor for easy nozzle attachment and compatibility.
- Spray flow rates adjustable between 5 mL/min and 40 mL/min, suitable for various solution viscosities (1–100 mPa·s).
- Average droplet size below 25 microns, depending on solution viscosity.
- Includes digital current meter for monitoring ultrasonic power consumption.

Typical Applications
This ultrasonic spray system is ideal for laboratory-scale thin film deposition via spray pyrolysis, coating substrates with uniform layers of metal oxides, semiconductors, or other solution-processed materials. It supports research in materials science, photovoltaics, sensors, and nanotechnology where controlled droplet size and spray patterns are critical.
Configuration & Operating Notes
The system requires an external syringe pump (not included) to deliver liquid solutions at controlled flow rates. Optional accessories include a compressive air vortex shaper to improve spray uniformity (compatible with cylindrical nozzles) and various nozzle shapes available on request. For safety and optimal performance, operation inside a fume hood is recommended. High-viscosity liquids may require alternative ultrasonic heads operating at higher frequencies (e.g., 120 kHz).
