1 Product description
Power-reduced "BactoSonic" ultrasound special bath with diverse implant boxes, box holders and
other accessories. The type specification and serial number are found on the type plate on the
rear side of the ultrasonic bath.
Product features:
• Stainless steel oscillating tank (1) with transducers, ultrasound frequency 40 kHz
• Time switch for 1-15 min and continuous operation (2)
• Power selection switch (3) for 20-100%
• Filling level mark for safe filling (4)
• Compact, easy-to-clean stainless steel housing (5)
• Rubber feet for safe positioning (6)
• With ball valve (7) for easy draining of the bath fluid and handles (8)
1.1 Mode of operation
BactoSonic ultrasonic baths use the effect of cavitation. Under their oscillating tank bottoms
they contain piezoelectric transducers, the energy of which is transferred to the bath fluid with
ultrasound frequency as mechanical oscillations. As a result, microscopically small bubbles are
continuously formed in the bath fluid, which release energy upon imploding and generate local
micro currents. This process is called cavitation.
Compared to other ultrasonic baths, sonication in the BactoSonic is conducted using low-
frequency ultrasound at low intensity within the cavitation threshold range. In doing so, the
adhesiveness of the biofilm to the implant surface is altered by active micro currents, shear forces
and oscillating cavitation bubbles to such an extent that it detaches. Resulting cavitation events
possess so little energy, however, that they do not cause any significant damage to cell structures
and the microorganisms released are available for the subsequent analysis.
BactoSonic ultrasonic baths are efficiently supported by SweepTec automatic frequency control.
SweepTec immediately balances load-dependent working point fluctuations to the optimal working
point using fast frequency modulation. This produces an especially homogeneous and uniform
ultrasound field in the bath volume for constantly reproducible results.

1.2 Purpose
Gentle separation of biofilms (main application)
The BactoSonic ultrasonic bath may be used to detach biofilms gently from the surface of infected
implants, as part of the scientifically-funded "Processing of implants using sonication methods".
The microorganisms that are obtained in this manner are available for analysis following cultivation
and make a prompt differential diagnosis possible in the event of implant infections.
In this connection, the ultrasonic bath is classified in accordance with Directive 98/79/EC on
medical devices as an in vitro diagnostic device and is to be treated as such.
Sonication is always carried out in connection with a suitable preparation that is added to the
bath liquid. In order to use the device as intended, the implant boxes and box holders supplied
are further needed to collect the implants and place them in the oscillating tank during sonication
(indirect sonication). Only in this manner is the optimum diffusion of the ultrasound guaranteed.
The ultrasonic bath is operated from the front. The operation is usually carried out on a table.
Further possible applications.
As an alternative to its main application, the BactoSonic ultrasonic bath may also be used for
the gentle and intensive cleaning of objects of diverse shapes, types and sizes and to support
chemical processes, e.g., during the preparation and treatment of samples. Accessories additional
to those included in the scope of supply may be required, depending on the application, to
guarantee proper sonication.
Caution
The user is fully responsible for the employment of suitable treatment and lab processes together
with the BactoSonic.

4 Use
The correct handling of the ultrasonic bath is described in the following. The process for sonication
of implants is to be conducted in accordance with the enclosed, scientifically-based "Diagnostics
of implant infections via sonication" process instructions. These also include bibliographical
references to such processes.
The preparation of the implant boxes is to be conducted pursuant to the enclosed "Implant boxes"
preparation instructions.
For additional instructions and queries regarding this process, please send an E-mail to info@
bactosonic. com.
Depending on the application, the implants are sonicated indirectly
in the implant boxes supplied or in other sample vessels, which are
positioned in special holders in the contact liquid within the oscillating
tank, in order to detach the biofilms.
Indirect sonication in inset beakers is to be additionally conducted for
special applications:
- Sonication of sample fluids.
- Use of chemically aggressive fluids (e.g., using acids as cleaning agents).
- Removal of chemically aggressive soiling (e.g., cleaning of developing
machine racks).
- Removal of abrasive soiling (e.g., polishing pastes, quartz, sand).
Remarks on direct sonication
For all other applications, sonication may be conducted directly.
For this purpose, the objects to be treated are placed in a basket and hung
inside the oscillating tank which is filled with bath liquid.

4.1 Instructions for use
Instructions - filling
• Verify that the ball valve is closed.
• The ultrasound must be turned off.
• Do not fill oscillating tank with hot water. Maximum filling temperature: 50°C.
• Water of at least drinking quality must be used to fill the oscillating tank.
• Water without additives is not suited for sonication. BANDELIN recommends the TICKOPUR or
STAMMOPUR preparations.
• Only use distilled or deionised water without additives in inset beakers or insert tubs.
• The fill level must always be at or slightly above the filling level mark.
A low fill level will damage the ultrasonic bath!
• Do not use any combustible fluids (e.g., benzine, solvents) or chemicals that contain chloride
ions or that separate (some disinfection agents, household cleaners and dish detergents) for
sonication in the stainless steel tank.
• When working with aggressive preparations in inset beakers or insert tubs: Prevent the contact
fluid or stainless steel surfaces from being sprayed. If necessary, replace the contact fluid, clean
the surfaces and wipe dry.
• When using preparations, the safety instructions included in the respective product leaflets are
fundamentally to be adhered to.
• Replace used sonication fluids, do not refresh them by adding more fluids.
Notes - Inserting objects
• Fully remove air bubbles from cavities (e.g., blind holes).
Indirect sonication
Fully remove possible air bubbles from underneath the vessels.
Notes - Temperature
• Warmed-up fluids intensify the ultrasound effect.
Experience has shown that the best results are obtained with a bath temperature of 50 bis
60 °C. At higher temperatures, the effect of the ultrasound cavitation decreases, however/2.
• Ultrasound energy warms up the bath fluid (even without additional heating). The temperature of
the bath fluid can increase rapidly if the ultrasound is active for long periods of time and/or the
oscillating tank is covered.
Therefore, control the temperature when treating temperature-sensitive components.
• To protect the electronic components inside the ultrasonic bath, the ultrasound output is
reduced upon reaching a critical temperature in order to inhibit a further increase in the interior
temperature.
• The fluid in the oscillating tank must not exceed a maximum operating temperature of 100°C.

4.2 General application
Step 1: Fill oscillating tank
The oscillating tank is filled with water and a suitable preparation to reduce the surface tension,
see chapter 7.3.
Indirect sonication
When using aggressive acidic liquids (e.g., sulfuric acid, hydrochloric acid), we recommend using
alkaline contact liquid such as 5% TICKOPUR R 33.
Fill 1/3 of oscillating tank with water.
Add surfactant.
Fill carefully, avoid as much as possible
the formation of foam.
The oscillating tank must be filled
contingent upon the inset beaker since
inset beakers displace the contact liquid.
Direct sonication
Fill 1/3 of oscillating tank with water.
Add dosed preparation to the oscillating
tank. See appendix for dosage
information.
Fill carefully up to the filling level mark,
avoid as much as possible the formation
of foam.
Step 2: Degassing the fluid
Freshly-filled bath fluid or fluid that has remained in the oscillating tank for a longer period of time
must be degassed prior to use. See also chapter 4.3.1.
Remove basket and other accessories from the oscillating tank.
Place lid on top.
Set the power selection switch to 100% P.
Switch ultrasound on for 10 min, see chapter 3.1.2

1electronic GmbH & Co. KG • Heinrichstraße 3-4 • 12207 Berlin • Deutschland • [email protected]
Step 3: Insert objects to be treated
For optimal diffusion of the ultrasound and protection of the oscillating tank, nothing should be in
contact with the bottom of the bath during sonication. Implant boxes and other inset beakers must
be stored in the supplied box holders or similar accessories. Suitable baskets are to be used for
placement of objects to be cleaned, see chapter 7.
Before every sonication it is necessary to check whether the sonication fluid needs to be cleaned
or replaced.
Indirect sonication
Hang the box holder in the oscillating tank and fill it with implant
boxes/inset beakers.
Fill box/inset beaker, in doing so please note:
• It is possible to treat multiple sample vessels with different fluids
at the same time.
• When treating small quantities of combustible fluids, the country-specific guidelines/
regulations that are currently in effect are to be observed.
Place the box/inset beaker on the holder, in doing so please note:
• Immersion depth of the box is min. 2 cm.
• Control fill level (contact liquid).
• Remove air bubbles below the box.
Direct sonication
Place the objects to be cleaned in the appropriate accessories, in doing so
please note:
• Evenly distribute parts, do not stack them.
• An overloading of the basket or inset beaker reduces the ultrasound
effect (the ultrasound is absorbed).
• Place the more heavily soiled side facing downward.
• Parts with joints are to be fully opened before placing inside.
• Delicate parts are not to come into contact with one another - for positioning, use special
accessories such as silicone knob mats if necessary, see chapter 7.
• Due to the design, the ultrasound effect is weaker on the outlet side. Heavily contaminated
objects should not be placed in the basket over the outlet.
Hang the inset basket with the goods to be treated or place the basket holder in the oscillating
tank and the inset basket on the basket holder.
Verify that the objects to be treated are fully covered by fluid.
With every object inserted, the fill level is to be monitored.

1electronic GmbH & Co. KG • Heinrichstraße 3-4 • 12207 Berlin • Deutschland • [email protected]
Step 4: Ultrasound - operation
Fundamentally, the sonication time is to be as short as possible in order to protect the objects to
be treated and the oscillating tank.
Place lid on top.
Set the desired sonication time, see chapter 3.1.2.
Step 5: Removing treated objects
After sonication, the objects are to be removed from the ultrasonic bath. Allowing them to remain
any longer in the bath fluid may damage them.
Switch offthe ultrasound.
Remove the inset beaker and/or basket from the tank and safely set down atop a level
surface.
Depending on the length of sonication, the beakers/objects may be hot!
After the cleaning processes, rinse the treated objects with water of at least drinking quality.
Visually review the sonication results.
Before the next sonication, verify the service life (see chapter 4.3.2) of the bath fluid. Heed the
specifications of the preparation manufacturer. If necessary, empty the oscillating tank.
Step 6: Empty the oscillating tank.
Layers of contamination on the tank bottom reduce the ultrasonic output.
The oscillating tank is to be emptied after a long period of use or sonication of heavily soiled
objects, see chapter 4.3.2.
Pull the mains plug out.
Do not place the ultrasonic bath in the sink.
Empty the oscillating tank by placing the ball valve handle in the
direction of discharge to open outlet.
After emptying the oscillating tank, rinse it thoroughly. Then dry with a
soft cloth.
For further care instructions, see chapter 5.

Degassing the bath fluid increases the ultrasound effect.
Freshly-filled fluid or fluid that has remained in the oscillating tank for a longer period of time
must be degassed prior to use. Gases released in the fluid (e.g., oxygen) are reduced through
degassing and the ultrasound effect is thus significantly improved.
The cavitation noise changes during degassing, loud degassing noises disappear at the end of the
degassing process, the ultrasonic bath appears to work more quietly.
A lower noise level, however, does not mean a reduction in ultrasonic power. It rather means the
end of the degassing process and an improvement in the ultrasound effect.
4.3.2 Disposal of sonication fluids
The working solution is disposed of pursuant to the specifications of the product leaflet and
the label. All aqueous preparations of DR H. STAMM GmbH are prepared pursuant to the
regulations of the Washing and Cleansing Agents Act, are biodegradable and may be added to
sewerage as working solutions. Strongly acidic and strongly alkaline fluids are to be previously
neutralised pursuant to technical data sheet specifications. The manufacturer specifications for the
corresponding preparations are to be observed.
If the solution contains after use substances that are dangerous to water, e.g., oils, heavy
metal compounds, etc., it must be prepared once the limit values are exceeded (removal of
contaminants) or disposed of as special rubbish.
Disinfection and cleaning agents that become contaminated when used are considered "waste
material" pursuant to the Waste Act (AbfG) and may not be taken back by the manufacturer.
In every case, the statutory provisions and regulations of municipal wastewater plants are to be
adhered to. Information is provided by municipal wastewater plants as well as by environmental
agencies.

5 Cleaning and maintenance of the ultrasonic bath
To achieve an optimum lifespan for the ultrasonic bath, cleaning and maintenance are to be
conducted regularly.
CAUTION!
Disconnect the ultrasonic bath from the mains before cleaning / maintenance.
Do not rinse or immerse the ultrasonic bath in water and do not expose it to splash water.
5.1 Cleaning and care
Oscillating tank
The oscillating tank of an ultrasonic bath is a wear part.
It is continuously exposed to cavitation during ultrasound operation. Dirt particles remaining in the
tank abrade and damage the tank surface through the movement of the fluid, therefore
• Rinse the oscillating tank with water thoroughly and frequently and dry using a soft cloth.
• Regularly remove residue from the edges of the oscillating tank using a commercial stainless
steel cleaning product without any abrasive additives.
• Do not use steel wool, scrapers or graters for cleaning / maintenance.
• Rust particles from the water pipe system and metal residue from cleaning processes can
penetrate the passive protective layer of the stainless steel, "activating" the stainless steel to
begin rusting. The extraneous rust produces localised corrosion of the stainless steel. For this
reason, immediately remove small rust stains with a soft cloth and a commercial stainless steel
cleaning product without abrasive additives. Remove metal parts such as screws, filings, etc.,
from the oscillating tank.
Housing
• Do not use any abrasive cleaners, only commercial care products without abrasive additives.
• Housing is to be wiped offonly from the outside, use a suitable surface disinfectant if needed.
Afterwards, allow to dry offor wipe dry.
5.2 Disinfection
Oscillating tank and housing are to be regularly cleaned and disinfected pursuant to the hygiene
plan using a VAH-certified or effective surface disinfectant.
Accessories such as holders and baskets should be processed regularly in a cleaning and
disinfection unit.
5.3 Positioning / Storage
During long periods of non-use, the ultrasonic bath is to be stored in a cool, dry location. The lid
should be placed on top in order to protect the oscillating tank from outside contamination.
