4. DESCRIPTION OF MAJOR COMPONENTS
Generator
Includes all operating controls and indicators, detachable three-wire grounded line cord, fuse, external
power control jack and high frequency cable connector.
Process Control Feature of the Sonicator
3000
• Microprocessor Controller - allows precise control of output amplitude, elapsed processing time,
and cyclical rates during power pulsing. It encompasses the functions of the Digital Integrating Timer
and the Multi-Range PULSAR & Cycle Timer.
• Digital Integrating Timer - permits precise timing of ultrasonic energy, which can be applied in
one-second increments from one-second to 100 hours. The total desired processing time is entered
on the keypad. Both the processing time selected and actual total elapsed processing time is
indicated by an LCD readout. A start/stop control initiates or reinitiates timed ultrasonic processing.
A pause control allows manual pulsing or delay. The total preset time of active ultrasonic processing
is unaffected by pauses or pulsing, whether by hand or with the Multi-Range PULSAR & Cycle Timer.
• Multi-Range PULSAR
&
Cycle Timer - permits the application of ultrasonic energy to the sample
on a pulsed basis. Pulse on and off times are adjustable in 0.1-second increments from 0.5 seconds
to 1 hour each. Pulsed operation permits high intensity sonication while avoiding heat build-up in the
sample. It also allows particulate material being processed to settle back under the tip.
• OVERLOAD INDICATION - under certain load conditions, the amount of power supplied to the
convertor/horn assembly might overload the circuitry of the generator to the point of failure. In order
to prevent damage to the generator, an overload protection feature has been built into the unit. When
the output power exceeds design specifications, the output power will be disabled. The following
prompt will appear: "OVERLOAD! Press CLEAR to RESET". The Power Knob display will flash “888”,
and the alarm will beep.
•
Temperature Monitoring/Control of Processed Liquids
The temperature probe can be placed in the liquid being processed to monitor the temperature, to
shut down the unit when a programmable maximum temperature is reached, and to activate an
external cooling device to cool the liquid being processed. Note: Do not allow the temperature probe
to come in contact with the Horn or Probe.
Convertor (Transducer)
The convertor is a gray, cylindrical unit (mounting area), and black colored front driver (the first stage
of acoustic amplification) with a ½” - 20 threaded hole for horn attachment. A detachable high-
frequency cable is also supplied.
Horn (Probe)
A horn is a 5” resonant body that steps down from 1 ½” to a specific diameter tip. The horn serves as
the second stage of acoustic amplification. The horn may be solid or have a removable tip and is
supplied with a ½” – 20 threaded stud for attachment to the convertor and external threads around the
body for attachment of accessories such as a Microtip . Horns are available in three standard tip
diameters of ½”, ¾” or 1" and come in three different tip configurations. Tapped horns have a
replaceable Flat Tip; Solid horns do not have a replaceable tip; and Sapphire tipped horns have a
