Sono-Tek ultrasonic atomizing nozzles have long been considered the premier BCT and syringe barrel coating technology. The new MedXT series of BCT nozzles surpasses the performance of older designs, allowing tube equipment manufacturers to integrate the benefits of next generation precision ultrasonic coating into their manufacturing lines.
Ultrasonic nozzle systems uniformly apply clot activators and anticoagulants including Heparin, EDTA, Silica, and Acid Citrate Dextrose. Specially designed for easy integration into high volume OEM manufacturing lines, the unique slim design allows nozzle placement at standard BCT rack distances, with 10-up configurations processing up to 12,000 tubes per hour. Integration of the MedXT Series with the ECHO generator technology offers superior uniformity and repeatability of coatings. The precise fine tuning capabilities of the ECHO produces tighter drop distribution with smaller droplets for consistent and fast drying dispersions.
High volume coating systems are typically configured with an array of 10 ultrasonic nozzles, and are designed to integrate with manufacturer’s lines. Custom configurations are available. With over 20 years of experience with syringe barrel and blood collection tube coating processes, Sono-Tek works closely with our customers to provide the best solution for their production needs.
Benefits of Sono-Tek’s ultrasonic spray technology include high transfer efficiency of expensive solutions and very low flow rate capability with deposition rates in the microliters/hour range, enabling ultra thin coatings with very little waste. Ultrasonic nozzles operate by converting high frequency sound waves into mechanical vibrations, atomizing liquids into a soft, low-velocity spray of uniform, micron sized droplets that adhere to surfaces without overspray. The nozzle is a self-cleaning, non-clogging device due to continuous ultrasonic vibrations. Very little maintenance is required, unlike pressure nozzles or air atomizers.
One example of a common blood collection tube ultrasonic coating application is spraying a silica coating to accelerate clotting. Silica slurries are sprayed onto tube side walls, forming uniform thin films of silica particles. Ultrasonic spray is beneficial in this particular application since the ultrasonic vibration of the nozzle breaks apart any silica agglomerates, ensuring a homogeneous coating onto tube walls, as shown in the photo above.
Sono-Tek ultrasonic nozzles also offer the ability to control atomized spray to desired areas for layered blood collection tube coating applications.
