     Sono-Tek Offers New Line of Ultrasonic Spray Dryers for Laboratory Use

Milton, NY, April 17, 2007 - Sono-Tek Corporation (OTC BB: SOTK), announced
today the release of a new line of Laboratory Ultrasonic Spray Drying Systems -
The SonoDry Ultrasonic Spray Dryer. This new spray dryer is available in three
sizes, providing the ability to choose the proper size machine for differing
requirements:

- -     SonoDry 750 ( up to 750 ml/hr),
- -     SonoDry 1000 ( up to 1,000 ml/hr)
- -     SonoDry 1500 ( up to 1,500 ml/hr),

All SonoDry Spray Dryers are supplied with Sono-Tek's unique non-clogging
ultrasonic atomizing nozzle incorporated into them. SonoDry systems also have
the ability to use a traditional twin fluid air atomizing nozzle system as well.
Nozzle requirements can be specified by the customer depending on application
needs. The machines can handle both aqueous and solvent based liquids. All
systems include software that allows for recipe storage and complete data
logging of all system functions. A fully integrated magnetic stirrer and hot
plate are standard on both the SonoDry 1000 and SonoDry 1500. SonoDry systems
use a high yield twin cyclone capture system. Yields exceeding 95% can be
achieved for many applications.

Designed for flexibility to meet a variety of experimental needs, these systems
can be operated with an optional congealing nozzle for freeze drying
applications, with counter current nozzles to create larger particles, and with
a Teflon membrane scrubber to capture particles from sub-micron to nano-particle
sizes. These features make the system ideal for a wide range thousands of spray
drying processes for R&D and small batch production needs.

The SonoDry series of spray dryers is of particular importance to Product and
Process developers in the following industries: Pharmaceuticals (e.g. for drug
actives and intermediates, enzymes and low molecular weight proteins), Foods
(e.g. for nutriceuticals, herbal extracts and flavors) and Specialty Chemicals
(e.g. for fragrances, Cosmetics ingredients and nano-scale particles).

According to Dr. Christopher L. Coccio, President and CEO, "Sono-Tek has had
several years of spray drying experience in the US market, integrating our
ultrasonic nozzles into traditional spray dryers to help customers achieve
benefits such as non-clogging performance, which is particularly important with
some nano-particle containing liquids. The SonoDry system is capable of
achieving greater particle uniformity compared to traditional spray drying
methods, which can be important for some applications. We look forward to
presenting this new and versatile product to the global market."
