Sono-Tek Corporation is the world’s leader in stent coating technology. Our 30 years of technical expertise in ultrasonic spray technology has put us on the leading edge of precision medical device coating. With a commitment to providing leading-edge coating equipment, we offer the most advanced stent coating systems on the market.
- Sono-Tek ultrasonic nozzles have industry proven success in producing high quality stent coatings
- Soft, low-velocity atomized spray can be targeted with unmatched precision
- Small ultrasonically generated drops provide excellent penetration and inhibit webbing
- Minimal overspray (minimal waste)
- Wide range of delivery rates from 1-100 ml/hour
- Self-cleaning ultrasonic nozzle prevents clogging
- All system components are compatible with the typical solvents and polymers used in stent coating
(For example: solvents THF, acetone,DMAC, toluene, chloroform,; polymers: urethanes, polycarbonates, silicones, styrenes)
Operating Principle
The AccuMist system combines Sono-Tek's unique Microspray ultrasonic atomizing nozzle with low-pressure air to produce a soft, highly focused beam of small spray drops.
Compressed air, typically at 1 psi, is introduced into the diffusion chamber of the air shroud, which produces a uniformly distributed flow of air around the nozzle stem.
The ultrasonically produced spray at the tip of the stem is immediately entrained in the low pressure air stream. An adjustable focusing mechanism on the air shroud allows complete control of spray width.
The spray envelope is bow-shaped. The width of the bow is controlled by moving the focus-adjust mechanism in and out.
