1. INTRODUCTION
The Soniprep 150 Ultrasonic Disintegrator is a self-contained unit designed for
convenient tabletop operation. It incorporates an acoustic cabinet, which
reduces externally audible noise and ultrasound to a safe level. A transparent
door allows observation of the sample during sonication. The apparatus is
factory adjusted to the user's electrical supply voltage and frequency.
1.1 General Description
The generator is a solid-state transistor amplifier, which provides electrical
energy, at an output frequency of 23KHz, to a high efficiency piezo-electric
transducer, which converts the electrical energy to mechanical energy. The
transducer, mounted in the top of the disintegrator chamber, transmits
ultrasound by high frequency vibrations via a titanium alloy probe. There is a
choice of three probes, which screw into the transducer head and transmit
energy of approximate amplitude for any specific application. Each probe is
designed to operate at a nominal frequency of 23KHz concentrating the
resultant ultrasonic energy, as required.

The disintegrator is designed to cope with different requirements and will
ensure that there is the maximum possible acoustic energy at the tip for the
probe. Once the output level has been selected it is continuously maintained by
the automatic feed back from the transducer. A meter, calibrated in microns,
allows the amplitude to be monitored continuously.
An adjustable table and a retort clamp are mounted on a rod within the
chamber. The specimen to be treated is contained in a suitable tube clamped in
position or in a vessel placed on the adjustable table.
