The facility is located in Guangzhou, China, and is operated by Sono-Tek’s China Distributor, Unitak. The laboratory will primarily be focused toward Sono-Tek’s medical device coating systems, such as stent and balloon catheter coating equipment; as well as many nano-research applications.

Stated by Sono-Tek President, Steve Harshbarger, "The new China-based facility is our first clean room rated laboratory. The rapidly growing demand for high quality medical devices in China has made this a logical place for expansion of our worldwide laboratory capabilities. Sono-Tek already has a very large customer base in China for stent coating systems. This new site will allow China-based customers easy access to test our next generation stent and balloon coating machines, as well as our latest thin film coating equipment."
