INTRODUCTION 10

1. INTRODUCTION

The Soniprep 150 Plus 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 23 KHz, 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 23 KHz 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.

Control Panel Description

The control panel is situated on the right hand side of the unit. A brief
description of their individual functions follows:

Amplitude Meter - The meter is calibrated in microns and monitors the probe
amplitude, that is, the actual movement peak-to-peak that is taking place at the
transducer/probe interface. Multiplying the meter indication by the
transformation ratio of the particular probe in use (See Table 1) allows actual
movement of the probe tip to be determined.

Power Control –The UP and DOWN arrows next to the Amplitude meter
window are used to increase or decrease the amplitude level displayed on the
amplitude meter. (In order to set the amplitude level the green start button

has to be pressed first)

This control permits stepped selection of power output to the transducer,
providing an accurate and reproducible amplitude setting for the particular
probe in use.

Timer - This is a 99 minute timing unit which can be used for timed runs or in a
continous running mode. At the end of a timed run the Soniprep will turn itself
off and the timer will reset itself to the last selected time. The timed run will start
when the GREEN start button is pressed.

The timed run required is selected by the UP and DOWN arrows next to the
TIME window. Set the time required and press START (green switch). The
sonication lamp will be illuminated, ultra sonication will commence and the timer
will start run-down to zero. When the time selected has expired, the unit will
switch off automatically and the sonication lamp will go off.

Time Hold Switch - When selected and the start (GREEN) button is pressed
the unit will operate continuously and the minutes of operation will count up.

Sonication Lamp - When the lamp is illuminated, it indicates that the power is
through to the transducer and there fore to the probe.

1.2 Power Supply and Fuses

When the equipment is first received, the voltage selector switch has been
set by the manufacturer and is in the correct positioned to suit your local power
supply.

Two anti-surge fuses are factory fitted in the holders located beneath the mains
inlet connection socket.

Location of the Instrument and Electrical Connections
Place the Soniprep 150 Plus on a suitable table or bench and ensure that at the
rear of the instrument is at least 50mm (2’) away from the wall to allow
adequate air circulation.

2. PROBES

2.1 Description and Function

The probe is a resonant element used for the transmission of vibrating
mechanical energy from the transducer to the sample. The prime purpose of
the probe is to increase the transducer amplitude to a usable level or, to select
the acoustic power transfer. Ideally, material used for such probes should have
good acoustic properties, high fatigue strength, low acoustic loss and density. It
is essential that it should also be corrosion and erosion resistant and relatively
inert to the materials being sonicated. The material that possesses all these
qualities is titanium alloy and it is from this material that probes available for use
with the disintegrator, are manufactured.

Note: Probes are specially designed to suit the Soniprep 150 Plus models
and are tuned to 23 KHz.

2.2 Exponential Microprobe

This probe has been specifically designed for the treatment of small quantities
of sample, up to 5ml. It should, preferably, be used with the 20ml tube and
sealing cap but any other suitably sized tube may be employed.

2.3 Fitting a probe to the Transducer

Clean the mating surfaces of the probe and transducer with a soft cloth.
Before fitting the probe, screw the coupling stud into the transducer

approximately 10mm leaving approximately 10mm protruding. Screw the probe
onto the stud in the transducer head, by hand. Then tighten firmly using the
tommy bar provided through hole in the probe. In the case of the exponential
probe use the spanner provided.

It is important that the probe is clamped securely to the transducer, as failure to
do so will result in a large power loss and an irritating high-pitched noise.

NOTE: The coupling stud is a relatively loose fit in both the transducer
and the probe to ensure that the contact surfaces are allowed to mate
perfectly. An extremely small

smear of silicone grease on the probe head

will facilitate surface mating.

2.4 Position of the probe in the liquid for treatment

When maximum power is necessary for a difficult application, the probe tip
should be immersed into the solution to an optimum depth.

As a guide, for 50ml sample down to 10ml sample, the best position for the
probe tip is 1cm below the surface of the sample. If the sample is less than
10ml, the best position for the probe tip should be found by trial and error.

Excessive depth and also the viscosity of the solution will cause the power to be
damped, which will be evident by a lower indication on the amplitude meter.
Conversely, if the probe tip is insufficiently below the surface, there will be a
tendency to generate foam in the solution or to cause scattering of droplets out
of the vessel. This is especially so when using high amplification. If the solution
foams, there will be a distinct change in sound, i.e. virtually unloaded and little
energy is being transferred to the solution.

PROCESSING SAMPLES 16

Sometimes, when the solution is thoroughly aerated, the usual process noise
from the beaker or test tube will stop, i.e. no buzz or vibration will be heard.
Again, this is because there is little transfer of energy. When these conditions
occur, turn the power off for a few seconds and set the probe deeper. Gradually
increase the power and the solution will de-gas. The lower the power setting,
the smaller will be the quantity that may be processed without foaming the
solution. Do not allow the probe to come too close to, or make contact with, the
sides or bottom of glass containers as powdered glass may be formed in the
solution, or breakage may occur. Plastic tubes are more resistant to failure
during sonication, but the insulation properties of plastic may make it difficult to
keep the sample cool.

CAUTION
Please bear in mind that sonication can weaken glass tubes. It is
therefore, advisable that glass tubes used in sonication are not
subsequently centrifuged at high speed as failure of the tube may result.

2.5 Probe Maintenance

In use the probe will erode by the action of cavitation in the liquid. This
dissolution of the metal from the tip of the probe, which occurs, with any metal
during use at high sound intensities is, however, reduced to a minimum by the
use of titanium. The erosion shows itself in concentric rings on the radiating
face. An eroded surface transfers energy less efficiently into the liquid than a
smooth one because of the formation of a zone of cavitation adjacent to the
surface. Energy not transferred into the liquid medium will tend to heat the end
of the probe. Furthermore, erosion continues at an accelerated rate on the
probe tip surface, which is already pitted, thus reducing the useful life of the
probe. For these reasons the tip of the probe should be polished smooth by
means of a very fine emery cloth on a flat surface, but note the following two

cautions.
CAUTION:

a) Probes WEAR OUT, although probes may be polished / reground, the

length of the probe must not be shortened by more than 2mm. PROBES
SHOULD BE REPLACED ANNUALLY OR AS REQUIRED.

b) The transducer/probe mating surfaces must not be cleaned with a non

abrasive cleaner. Should the end require polishing, ONLY A LIQUID NON

ABRASIVE POLISH should be used.

The Soniprep Plus has a red Fault light on the control panel

that will come on when the probe is required to be changed

PROCESSING SAMPLES 17

2.6 Testing Probe Performance

The following test should be carried out so that users may monitor the
performance of each probe.

Measure the temperature rise obtained at maximum power after 5 minutes with
the following volumes of chilled water (i.e. below 10°C).

Probe Volume of Chilled Water

Exponential 15ml

9.5mm 50ml
19mm 100ml

A temperature rise of approximately 35°C should be obtained. If the rise is not
obtainable, the probe or the transducer is at fault. To pinpoint the part of the
system, which is faulty, repeat the test with an UNUSED probe. If you still do
not obtain a temperature rise of approximately 35°C, then contact the service
centre at the address inside the front cover.

The service centre will give you more advice.

PROCESSING SAMPLES 18

3. PROCESSING SAMPLES

3.1 Vessels for Samples

NOTE:
Minimum Volume - Volumes of less than 1ml may be treated with the

exponential microprobe. The sample should be held in a micro tube.
Maximum Volume - A maximum of 100ml may be treated at any one time.

However, larger volumes may be processed by using the treatment vessels. It
is preferable to use a narrow vessel rather than a wide one. Twice the volume
in a narrow vessel takes a shorter time to process than the same volume in a
wider vessel. Twice the volume or concentration takes twice as long to process.
Materials that are particularly resistant to ultrasonic energy, however, should be
processed in the smallest area practicable. Since the energy radiates from the
probe tip in the shape of a cone, the more confined the sample under the tip
the better the results. A narrow, relatively short test tube is also called for when
processing small quantities, say of the order of 4ml. The probe tip should
displace as much liquid as possible to force a long liquid height or ‘head’ above
the vibrating tip. This prevents foaming or whipping the solution out of the test
tube. A wide beaker is not normally suitable.

There is considerable evidence that the shape of the container has great
influence on the rate of release of soluble protein or the efficiency of the cellular
breakage. This is probably more the function of mixing than anything else, since
the individual components are not directly exposed to the action of the probe tip
for more than a second or two. If the volume is very large, then individual cells
are not in the area of cavitation activity for a sufficient period of time. The probe
tip should be below the surface of the liquid by approximately 13mm (1/2’) and
should not be too far from the bottom of the vessel l(again approximately
13mm). If the tip is not satisfactorily immersed, a considerable quantity of air
may be trapped in the solution thus dissipating the power delivered and not
allowing it to be transmitted to the solution. As there is sufficient force
generated by the Soniprep 150 Plus to fracture or shatter glass, the probe tip
must not be allowed to come in contact with, or come close to, the bottom of
the vessel.

3.2 Basic Processing

Test tubes of 20ml and 100ml nominal capacity are available for certain
applications. In addition to these, cooled treatment vessels are available for use
when it is important that the media being treated should be subjected to
minimal temperature rise.

A range of rubber sealing caps are available for all tubes and cooled treatment
vessels. The probe is inserted through the sealing cap which fits over the mouth
of the vessel, or tube, and provides an air tight seal.

For ease of manipulation and to effect the best possible seal, the edge of the
hole in the sealing cap should be lightly smeared with silicone grease. When
using sealing caps, ensure the tube is securely clamped to prevent downward
movement of the tube and consequent disengagement from the probe.

PROCESSING SAMPLES 19

When fitting sealing caps, the air pressure which may have built up can be
released by lifting the edge of the cap slightly. The caps are manufactured from
a material which is suitable for autoclaving.

When treating samples in any of the test tubes the temperature of the
suspension will rise, especially if the quantities of the material being treated are
small. To avoid this temperature rise, immerse the tube containing the medium
in a beaker containing crushed ice or a suitable cooling mixture. The beaker
can be placed on the adjustable platform and the vessel containing medium
held in the laboratory clamp. However, if the medium being treated is
particularly sensitive to temperature, then one of the cooled treatment vessels
described in sections 3.3, 3.3 and 3.4 should be used.

3.3 Batch Treatment Vessel

This consists of an inner chamber to contain up to 50ml of sample to be
treated, surrounded by a cooling jacket through which a suitable cooling liquid
(e.g. iced water or alcohol) can be circulated.

3.4 Continuous Flow Vessel

This is available for the treatment of even larger volumes where the required
disintegration time is relatively short. This vessel has both inlet and outlet tubes
to the inner chamber which allows the sample to be passed continuously
through at a measured flow rate as disintegration takes place.

Apertures are provided in the back of the ultrasonic cabinet so that the
liquid feed-lines can be passed through to the treatment vessels and
permit sonication with the cabinet door closed.

APART FROM TURNING THE SONIPREPON AT THE MAINS AND SETTING
UP THE AMPLITUDE, THE PROCESS TIMER SHOULD BE USED TO
CONTROL THE SONIPREP ONLY.

( Please do not open the door whilst using the Process Timer because in
this mode the door interlock switch is not in circuit. )

Process Timer

THE WATTAGE METER (Part Number 46222-5020)

The wattage meter can be plugged into the back of the Soniprep to the 3 pin
din socket in order to see the power being dissipated into the sample.
The display on the meter shows the watts of power that the sample is receiving.
The display will show small up and down movements as the amplitude does
vary slightly depending on the peak or the trough of the sign wave.

CLEANING AND FAULT FINDING 22

Use a damp cloth for cleaning outside.
If internal chamber etc. requires disinfecting the following fluids may be used:

TERMINEX 2 (Available from Arrow Chemicals Ltd)
VIRKON (Available from Antec International)

These cleaning agents if used as instructed by the manufacturer should not be
harmful to this product, or accessories supplied for use with this product.

5. FAULT FINDING

5.1 General

Faults occurring during use can usually be traced to the titanium probe as this is
subject to high mechanical stresses. Possible faults are loss of effectiveness in
operation, a high-pitched screeching from the transducer unit and also a
wavering indication on the amplitude meter. The amplitude meter can be used
to monitor performance. Any fault condition will show as a loss of amplitude.

5.2 Fault conditions could be:

a) Probe insufficiently tightened.
b) Probe/Transducer faces not clean.
c) Probe too short.
d) Probe fatigued.
e) Transducer fault.

5.3 Loose Probe

A change in the pitch of the noise from the transducer (usually accompanied by
an indication on the amplitude meter) is a sure sign that the probe has worked
loose. Uncouple the probe from the transducer and clean both surfaces with a
soft cloth. Re-couple the probe to the transducer.

5.4 Fatigued Probe or Coupling Stud

Similar symptoms will be evident if the probe is fatigued, although this fault
would be detected at an earlier stage as there would have been difficulty in
obtaining satisfactory amplitude. However, to check that the fault is actually in
the probe, remove it and the coupling stud from the transducer and test the
probe's performance as described in section 2.6. If the probe is faulty, fit a new
one.

Again, symptoms common to a loose, or fatigued, probe may indicate a
fatigued stud. If necessary, renew it.
