Safety

23346-002 en/2023-03 7 / 38
2.4 Harmful to health due to ultrasound noise
The ultrasound noise typical of the process can be perceived as very unpleasant. Remaining
within a radius of 5 m for an extended period of time may cause damage to health.
• Wear suitable hearing protection.
• Use a lid to reduce noise.
2.5 Hazards due to high temperatures
The device, the sonication fluid and the sonication objects can become hot during operation.
Contact with these products may cause burns. The temperature can be set at up to 80 °C.
Ultrasound energy warms up the sonication fluid even without additional heater.
Prolonged ultrasound operation can lead to very high temperatures. In a device with heater,
the set temperature can be significantly exceeded by the energy of the ultrasound.
• Observe the treatment times recommended by the manufacturer of the ultrasound agent.
Do not leave the ultrasound switched on for longer than necessary.
• Do not reach into the sonication fluid with your hand. Remove sonication objects with
the insert basket or forceps.
• Allow the sonication objects to cool before touching them.
• When lifting from the handles, the hands may touch the edge of the tank which could be
very hot.
In the case of high-boiling liquids, the bath temperature can rise to over 120 °C due to
the energy input of the ultrasound. This can lead to fires and severe burns.
• Do not use combustible, explosive, non-aqueous liquids (e.g. petrol, solvents) or
mixtures with combustible liquids (e.g. alcoholic solutions) directly in the stainless
steel oscillating tank.
2.6 Danger due to ultrasound
The strong ultrasound in the device destroys cell structures. If part of the body is immersed
in the sonication fluid during operation, this can cause damage to skin and also damage
to internal tissue. The periosteum of finger bones can be damaged.
• Do not reach into the sonication fluid during operation.
• Never sonicate living creatures.
Safety

of the ultrasound agent used. The recommended ultrasound agents in the TICKOPUR
product line by DR. H. STAMM GmbH are biodegradable in accordance with the provisions
of Regulation (EC) No. 648/2004 (Detergents Regulation). If necessary, the sonication fluid
must be neutralised before disposal.
Depending on the type of contamination involved, water-polluting substances like oils
or heavy metal compounds may be introduced to the sonication liquid during cleaning.
If the threshold values for these substances are exceeded, the sonication liquid must be
processed or disposed of as special waste.
Observe local waste water regulations.
Safety

23346-002 en/2023-03 9 / 38
2.9 Erosion of the oscillating tank
The surface of the oscillating tank is subject to erosion. How quickly this erosion takes
place depends on the usage of the device. The erosion leads to leaks in the oscillating tank.
Bath liquid can thus leak into the interior of the device. Moisture on electrical components
can lead to an electric shock or fire.
• Stop using the device if you notice a leak. Disconnect the mains plug immediately.
Empty the oscillating tank.
You can extend the lifespan of the oscillating tank by observing the following instructions:
• Replace sonication fluid that is visibly contaminated by particles.
• Only use demineralised water (DI water) with an ultrasound-compatible agent.
• Do not use chemicals that contain or release chloride ions in the oscillating tank.
This is the case with some disinfectants, household cleaners and dishwashing detergents.
Chloride ions will corrode stainless steel.
• Only use the device with accessories that are suitable for the device and the objects
to be treated, e.g. a basket. Do not place any objects to be treated directly on
the bottom of the oscillating tank. An overview of suitable accessories can be found
in chapter 9 Accessories.
2.10 Preventing damage to the device
• Only use aggressive agents in inset beakers or insert tubs. When working with
aggressive agents, avoid splashing in the contact liquid or on the stainless steel surface.
Replace contaminated sonication fluid immediately. Clean surfaces and wipe them dry.
• The use of highly acidic agents can corrode the ball of the ball valve. The ball valve will
leak. If the use of a strongly acidic detergent cannot be avoided, use a stainless steel
ball valve.
• Do not operate the device without sonication fluid in the oscillating tank. Make especially
sure that the heater is switched off when the oscillating tank is empty. The fill level must
always be at or slightly above the filling level mark.

Design and function
3.3 Function
The device uses cavitation triggered by low-frequency ultrasound. Piezoelectric oscillating
systems are located on the underside of the oscillating tank. The ultrasound generates
strong pressure fluctuations in the sonication fluid. Cavitation bubbles are formed
at the pressure minima. At higher ambient pressure around the bubbles, they collapse
very quickly. This results in strong local microcurrents on the surfaces of the objects being
treated. This removes dirt from the surface of the objects. Dirt particles are removed
and fresh sonication fluid flows in.

removed with a suitable cleaning agent.
Preparation for operation

16 / 38 23346-002 en/2023-03
5 Operation
5.1 Ultrasonic operation
The objects to be treated are introduced in the oscillating tank with suitable accessories
such as an insert basket. There they have direct contact with the sonication fluid.
For suitable accessories for sonication, see chapter 9 Accessories.
5.2 Sonication fluid
A solution made from water and a special ultrasound agent is used as the sonication fluid.
Drinking water or demineralised water can be used for the water.
Water without any additives is unsuitable for sonication. Use of demineralised water
without an ultrasound agent leads to increased erosion of the ultrasonic oscillating tank.
The ultrasound agent used must foster cavitation and be biodegradable, easy to dispose of,
material-compatible and long-lasting. BANDELIN recommends ultrasound agents from
the TICKOPUR, TICKOMED and STAMMOPUR product ranges from DR. H. STAMM GmbH,
see chapter 10 Appendix.
• Telephone consultation: [phone]

Operation
5.3 Sonication time
NOTICE
Risk of damage to the objects to be treated
Prolonged sonication can damage the surface of sonication objects.
- Select the shortest possible sonication time.
The optimum sonication time depends on a number of factors:
• type and concentration of the agent,
• temperature of the sonication fluid,
• type of contamination,
• type of objects to be treated, in particular the materials.
Observe the specifications of the agent manufacturer regarding the recommended
sonication time.
To protect the objects to be treated and the oscillating tank, select at the start
the shortest possible sonication time. Check the result. Extend the sonication time
if the result is inadequate.
5.4 Filling with sonication fluid

5.6 Switching the heater on and off

WARNING
Risk of scalding
During heating, vapour bubbles can rise explosively under certain conditions
(retardation of boiling).
- Stir the sonication liquid occasionally during heating or switch on the ultrasound.
Heated sonication fluid intensifies the effect of the ultrasound. Experience has shown
that the best results are obtained with a temperature of 50 to 60 °C. This can reduce
the sonication time. At higher working temperatures, the effect of the ultrasound
decreases again.
Ultrasound also heats the sonication fluid. During continuous operation, the working
temperature of the sonication fluid can rise above the set value – particularly if
the oscillating tank is covered. Therefore, check the working temperature when
processing temperature-sensitive objects.
• Please heed the specifications of the agent manufacturer on optimum temperature.
• Pre-heating during degassing of the sonication fluid is ideal.
See chapter 5.7 Degassing the sonication fluid.
• Before pre-heating, remove the basket or other accessories from the oscillating tank.
Cover the ultrasonic oscillating tank with the lid if available.
Turn on the heater by turning the rotary knob to the desired temperature.
- The yellow and white indicator lights will light up.
- When the target temperature is reached, the yellow indicator light goes out.
5.7 Degassing the sonication fluid
Freshly-filled sonication fluid or liquid that has remained in the oscillating tank for a long
period of time must be degassed prior to use. Degassing of the sonication fluid increases
the ultrasound effect.
• Cover the ultrasonic oscillating tank with the lid if available.
• For degassing, switch on the ultrasound. The degassing time is 30 minutes.

Information
During degassing, the ultrasound noise becomes quieter. This means that the ultrasound
effect increases.
