Benchtop Desktop Ultrasonic Spray Coating System for Drug-Eluting Balloons & Peripheral Stents Medical Device

Core Technologies:
• Proprietary ultrasonic spray head with independent IP - Precise drug dosage control
• Unique aerosol humidification technology - Accelerates drug crystallization
• Flawless coating quality - No adhesion, pinholes, or defects
• Exceptional uniformity, stability, and consistency
• High corrosion resistance - Compatible with diverse organic solvents

System Overview:
This benchtop ultrasonic coating system is specifically designed for applying drug coatings to balloon catheters and peripheral stents. With compact dimensions for laboratory workspace compatibility, it is ideal for R&D or space-constrained environments. Equipped with TMAX's focused-flow or micro-flow ultrasonic spray heads, the system enables precise drug loading with uniform coatings free from pinholes or orange-peel effects. Specialized fixtures and rotational mechanisms support coating applications for coronary balloons, peripheral balloons, and stents, making it the industry-preferred precision coating solution.
