             Sono-Tek Introduces Its WideTrack Glass Coating System

    MILTON, N.Y., July 22 /PRNewswire-FirstCall/ -- Sono-Tek Corporation
(OTC Bulletin Board: SOTK), the world's leader in ultrasonic spray nozzle
technology, today announced the successful installation of its WideTrack glass
coating system on a production line of a major float glass manufacturer, and
firm orders for four (4) additional systems, totaling over $500,000 in sales,
scheduled to be installed over the next few months in plants located in the
Far East.  The WideTrack system is specifically designed to apply coatings
uniformly over wide areas, such as the protective coating being applied to a
12 foot wide moving ribbon of glass in this application. The major benefits of
this system compared to ordinary pressure nozzle systems typically used in
this application, is that the finely atomized spray generated by the WideTrack
system minimizes the amount of liquid that bounces off the glass surface,
thereby providing an environmentally sound solution, while, at the same time,
dramatically reducing material consumption and cleanup.

    According to Dr. Coccio, Sono-Tek's President and CEO, "This product
points out the diversity of uses for Sono-Tek's ultrasonic nozzle systems, for
example, in medical device manufacture, nanotechnology, and electronics
assembly.  In addition to the float glass application, WideTrack systems have
been used successfully to coat food products, skyscraper glass, touch screen
displays, and in various other industrial applications.  I am very pleased
with the ease of installation and the excellent results achieved by the
WideTrack System on this production line.

    With regard to the general state of the business, our order backlog in
most of our market areas has reached record levels, prompting us to expand our
manufacturing capabilities to meet this increasing customer demand."
