Ultrasonic Coating System for Syringe Barrel & Blood Collection Tube Coating
Ideal for R&D* or low-volume production, the ExactaCoat system is configured with Sono-Tek precision ultrasonic atomizing nozzles for coating the side walls of blood collection tubes or syringe barrels with Heparin, Silicone, lubricants, hydrophylic/hydrophobic coatings, Teflon, barrier films, or clotting agents. Sono-Tek has been supplying precision blood collection tube coating equipment to manufacturers worldwide for decades. The ExactaCoat system provides a full coating solution, with automated drying sequence following atomized coating, using a drying gas hypotube.
*Production volume coating systems also available.
The ExactaCoat for syringe & blood collection tube coating features:
- Compact benchtop design that favors portability
- 400 mm x 400 mm x 100 mm (15.75” x 15.75” x 3.94”) range of motion
- Windows®-based programming software with image import (PC included)
- Remote trackball teach pendant
- Coordinated motion in all three axes simultaneously
- Fully automated, full coating solution
- Automated drying sequence increases throughput

Sono-Tek’s extended horn and radial spray nozzles feature soft, atomized spray that adheres to side walls without collection of material on the base of the tube. Capable of targeted coatings of small sections or the entire barrel, as well as layering of multiple coatings.
Sono-Tek ultrasonic nozzles feature:
- Up to 80% reduction in material
consumption - Reduced wasteful overspray
- Highly controllable spray produces
reliable, consistent results - Uniform drop sizes resulting in highly
uniform coatings - Precisely defined, repeatable, micron
thick coatings - Capable of very low flow rates
The ExactaCoat system is also used for coating the inside diameters of ampules, inhalers, vials or other cylindrical vessels


The Extended Horn ultrasonic nozzle (left) creates a narrow, focused spray pattern, providing excellent coverage with very little over-spray of material.
The Radial Spray ultrasonic nozzle (right) produces a wide spray pattern capable of targeting sections of tubes and syringes.
