1 Product description
Ultrasonic bath of type SONOREX DIGITEC DT ... oder SONOREX DIGITEC DT ....-RC
The exact 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 35 kHz
• Digital timer for 1, 2, 3, 4, 5, 10, 15, 30 min and continuous operation (2)
• Filling level mark for safe filling (3)
• Compact, easy to clean stainless steel housing (4)
• Rubber feet for safe positioning (5)
• As of type DT 102 H, drain outlet with ball valve (6) for easy discharge of bath liquid and
handles (7)
• Depending on model, comes with heating (type "H"), infrared interface with the bottom side
(types “RC”) or a special oscillating tank (types "C")
1.1 Mode of operation
SONOREX 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 liquid with
ultrasound frequency as mechanical oscillations. As a result, microscopically small bubbles
are continuously formed in the bath liquid, which release energy upon imploding and generate
local micro currents. This process is called cavitation. During cleaning processes, it causes
contamination to be regularly "blasted" from the hard surfaces of the objects being treated. At
the same time, dirt particles are dispersed and fresh bath liquid flows in. During sonochemical
processes, cavitation may have a catalytic effect, e.g. with the production of stable emulsions or
the rapid degasification of fluids with a high gas content.
SONOREX 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
General application
SONOREX ultrasonic baths are intended for the sonication of aqueous fluids. They work on the
basis of low-frequency ultrasound and can be used in versatile ways. Their main application is
gentle and intensive cleaning of objects of diverse shapes, types and sizes. Alternatively, chemical
processes can be favourably supported and accelerated in an ultrasonic bath, e.g. when preparing
or treating samples.
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, a basket or another inset beaker, into which objects
are placed during sonication, is also required. 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.
Ultrasound treatment of medical instruments
SONOREX ultrasonic baths are used to treat medical instruments:
a) during manual treatment
b) before machine treatment
c) after machine treatment
In this connection, they are to be used together with suitable, non-fixative disinfection and/or
detergent preparations, in order to support or expedite their effect. Pursuant to section 2, para. 1
and section 3, paras. 1, 9 and 10 of the Medical Devices Act (MPG), the ultrasonic bath thus
becomes a medical device as an accessory to the preparations, and is to be treated as one.
This includes pre- and post-processing steps for the medical instruments, e.g. the observance
of KRINKO/1 recommendations in "Hygiene requirements for the treatment of medical products"
and other applicable domestic regulations. Additional information in this respect can be found in
chapter 4.3.
1.3 CE conformity
SONOREX ultrasonic baths are declared as medical products/2 and satisfy the CE marking criteria
for the European
- "Medical Device" directive
- "Low-voltage directive"
- "Electromagnetic compatibility" directive
- WEEE - Directive
in their currently valid versions.
A declaration of conformity can be requested from the manufacturer by providing the serial
number.

During operation, portable or mobile HF communication systems in the vicinity of the ultrasonic
bath should be turned off - their operation may be disrupted.
1.5 Warnings and safety precautions
General
• Keep the ultrasonic bath out of the reach of children and persons who have not been instructed
in its operation by reference to these instructions.
• We will not offer a guarantee for damages to the ultrasonic bath or oscillating tank, or to the
objects to be treated, as a result of use of inadequate disinfection agents or detergents.
• Keep the surface of the ultrasonic bath and operating elements clean and dry.
• Do not expose the ultrasonic bath to corroding influences.
• Move the ultrasonic bath only when it is empty.
• Empty the ultrasonic bath only while turned off.
• Ultrasonic baths adhere to prescribed EMC limit values, such that it can be assumed that the
electromagnetic radiation emanating from the units is harmless to humans. A binding statement
for wearers of implants can only be made at the place of work and together with the implant
manufacturer, however. In case of doubt, information regarding the allowable electromagnetic
exposure level is to be obtained from the implant manufacturer.
Operation
• Observe ambient and set-up conditions, see chapter 1.4.
• Only plug in the ultrasonic bath to an outlet with a grounded socket.
• Do not operate the ultrasonic bath without fluids.
• Do not stand or lay any objects on the tank bottom, accessories must be used, see chapter 7.
• Do not immerse any parts of the body (e.g. hands, feet) or living beings (animals or plants) into
the tank; in particular, do not immerse them in the ultrasonic fluid during ultrasound operation.
Danger: Ultrasounds have a cell-destroying effect.
• In the event of continuous activity within a 2 m radius, adequate hearing protection must be
used. Danger: Hearing disturbances during operation when not wearing hearing protection - the
typical ultrasound cavitation noise can be very uncomfortable.
• When preheating the bath liquid, stir at least every 15 min. or switch on the ultrasound. Danger:
Scalding due to retardation of boiling.
• Do not operate the ultrasonic bath while unattended.
Advice for the medical field
• The ultrasonic bath is exclusively intended for use by medical skilled personnel.
• When handling contaminated instruments, relevant personnel protection regulations are to be
observed.
• When treating instruments, the instructions of the instrument manufacturer are to be followed.
• Ultrasound cleaning is especially suited for instruments made of stainless steel and hard
plastics. Do not treat lenses, camera systems or light cables with ultrasound.

3 Operation
3.1 Operating elements
The ultrasound and the heating system are operated from the front:
3.1.1 Ultrasound
While switched on ultrasonic bath - key ON/OFF - the ultrasound is
activated with the key Start/Stop after preselection of the time.
Timed operation
• Setting via keypress
Time 1, 2, 3, 4, 5, 10, 15 or 30 minutes
- After pressing the key Start/Stop a running light shows optically the balance
time.
- After run off of selected time, the ultrasound stops automatically.
• By pressing early the key Start/Stop this will stops the ultrasound.
Continuous operation
• Setting via keypress
LED illuminated
- After pressing the Start/Stop key the top (green) LED lights up constantly.
- Ultrasound is not switched of automatically,
to switch of press the Start/Stop key.
Notes
• For safety reasons the unit will be automatically switched off, if no key has been pressed longer
than 12 hours.
• While turned off, the ultrasonic bath may remain connected to the mains.
It can be disconnected from the mains by pulling the mains plug.

1electronic GmbH & Co. KG • Heinrichstraße 3-4 • 12207 Berlin • Deutschland • [email protected]
3.1.2 Heating
The heating system is operated with the key temperature preselection.
After switching on the ultrasonic bath the green LED “0” is illuminated.
• Set the target temperature via keypress
Temperature range 20-80 °C
- target temperature = lighting, yellow LED.
- actual temperature = blinking, yellow LED.
Above the adjusted target temperature LED is blinking
slowly (= heating is off), below the target temperature
LED is blinking quickly (= heating is on).
- When the actual temperature is equal to the target temperature,
only the LED of the target temperature lights up.
The LED „!” will blink red when temperature exceeds 80 °C.
- Switch off heating manually:
Press temperature preselection key longer than 2 sec.
The green LED “0” is illuminated.
Notes
• The heating system works independently from the ultrasound.
• Last selected temperature will not be stored.
When switching on the ultrasonic bath again (ON/OFF) the target temperature “0” is given.
• The heating will automatically turn on every time that the bath temperature drops below the set
temperature.
• The display accuracy of the temperature scale is ± 2,5 °C.
The red LED is triggered at around 80 °C + 5K.
• The heat automatically switches off to protect the ultrasonic bath from overheating.
The ultrasonic bath will need to cool down sufficiently (water temperature around 50 °C) and be
disconnected from the mains power briefly before it can be used again.
• Ultrasound energy warms up the sonication fluid (even without additional heating).
- In case of continuous sonication and/or covering the oscillating tank, the fluid temperature
will increase, even rising above the value set on the thermostat. For this reason, check the
temperature when treating temperature-sensitive components.
- Non-aqueous fluids can heat up many times faster than water. A possible flashpoint can be
reached and/or exceeded after a very short sonication time. In the case of high-boiling liquids
(with and without a flashpoint), the bath temperature can increase to >120 °C due to the
energy input of the ultrasound. This leads to irreparable damage to the ultrasonic bath.
Avoid retardation of boiling
When a temperature is set, the unit will immediately try to reach the selected temperature.
When heating (without ultrasound) switched on ultrasound will be automatically switched on once
during 3 seconds every minute for mixing the liquid and thus avoiding retardation of boiling.
- This function is always active with temperatures > 60 °C and cannot be deactivated!
- The function can be activated for temperatures < 60 °C. It must be activated again after
each switch-on: activation of the function:
Press the key temperature preselection while at the same time switching on the
unit (ON/OFF).

4 Use
Direct sonication
Normally, sonication takes place directly in the oscillating tank. For this
purpose, the objects to be treated are placed in a basket and hung inside the
oscillating tank which is filled with sonication fluid.
Indirect sonication
Indirect sonication in inset beakers is to be conducted for special
applications or to protect the stainless steel oscillating tank in the case of:
- 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 contamination (e.g. polishing pastes, quartz, sand).
For indirect sonication, a contact liquid (water + surfactants) must be filled in
between the inset beaker and the oscillating tank.
4.1 Instructions for use
Instructions - filling
• For ultrasonic baths with outlet, verify that the ball valve is closed.
• Ultrasound and heating must be turned off.
• Do not fill ultrasonic tank with hot water. Maximum filling temperature: 50 °C.
• At least drinking-quality water 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, explosive, non-aqueous liquids or azeotropic mixtures directly in
the stainless steel oscillating tank (e.g. benzine, solvents). Furthermore, chemicals that contain
or that separate chloride ions (some disinfectants, household cleaners, and dish detergents),
may not be used directly in the stainless steel tank.
• When working with aggressive preparations in inset beakers or insert tubs: Prevent the contact
liquid or stainless steel surfaces from being sprayed. If necessary, replace the contact liquid,
clean the surfaces and wipe dry.
• When using strongly acidic preparations, the hard chromium plating of the ball valve may
become corroded and the ball valve start to leak.
If the use of a strongly acidic cleaning agent cannot be avoided, the use of a stainless steel ball
valve is recommended.
• When using preparations, the safety instructions included in the product leaflets are to be
fundamentally adhered to.
• Replace used sonication fluids, do not refresh by adding fluids.

Notes - Inserting objects
• Fully remove air bubbles from cavities (e.g. blind holes).
Indirect sonication
Remove any air bubbles from underneath the
vessels.
Notes - Temperature and heating
• Warmed-up fluids intensify the ultrasound effect. Experience has shown that the best results
are obtained with a bath temperature of 50 to 60 °C. With high temperatures, the effect of the
ultrasound cavitation decreases; however/3.
• In order to save time during use, the bath fluid may be preheated during degassing.
• For an optimum bath temperature, observe the specifications of the specimen manufacturer!
• 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 may not exceed a maximum operating temperature of 100 °C.
• Prepare the disinfectant with cold water, operate the ultrasonic bath without heating and avoid
temperatures above 40 °C.

4.2 General use
Step 1: Fill oscillating tank
The oscillating tank is filled with water and a suitable preparation to reduce the surface tension,
see chapter 7.2.
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.
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.
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.
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 4.4.1.
Remove basket and other accessories from the oscillating tank.
Switch on ultrasonic bath.
Place lid on top.
For degassing, set the time and start the ultrasound (Press START/STOP button for 2 sec),
see chapter 3.1.1 and 3.2.
- up to 10 litres bath volume: 10 min
- more than 10 litres bath volume: 30 min
Time need to be extended with acidic cleaning solutions.
Step 3: Preheat fluid
In ultrasonic baths with built-in heating, the fluid may be preheated independently of the
ultrasound. This increases the ultrasound effect, especially when removing fats, oils and polishing
paste residue, and shortens the duration of the subsequent ultrasound.
Remove basket and other accessories from the oscillating tank.
Place lid on top.
Set the desired temperature, see chapter 3.1.2. The ultrasonic bath begins to heat
immediately.
For an even warming of fluids, stir the fluids or switch on the ultrasound for a few minutes now
and then, otherwise there will be a retardation of boiling - risk of scalding!

Step 4: Insert objects to be treated
Before every sonication it is necessary to check whether the sonication fluid needs to be cleaned
or replaced.
Direct sonication
Hang the insert basket with the goods to be treated, or place the basket
holder in the oscillating tank. Place the inset basket on the basket holder.
Check that the objects to be treated are fully covered with fluid.
With every object inserted, the fill level is to be controlled.
Indirect sonication
Place the positioning lid atop the oscillating tank and hang the inset
beakers from the positioning lid, or hang the insert tub directly in the
oscillating tank.
Immersion depth for inset beakers is min. 2 cm.
Control fill level (contact liquid).
For cleaning tasks
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.
For indirect sonication of fluids
Fill sample vessel(s), 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 in sample vessels, the country-specific
guidelines/regulations that are currently in effect are to be observed.
Step 5: 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.
In the case of disinfection fluids, the length of time will depend on the concentration of the
respectively used preparation.
In the case of stubborn residue, conduct sonication for a longer time if necessary.
Place lid on top.
Set the desired sonication time and switch on ultrasound, see chapter 3.1.1.

Step 6: 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 off the ultrasound.
Remove the basket or inset beaker from the tank and set down atop a level surface.
Caution
Depending upon the set temperature or the duration of sonication, the baskets and 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 4.4.2) of the bath fluid. Heed the
specifications of the preparation manufacturer. If necessary, empty the oscillating tank.
Step 7: 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 4.4.2.
Switch off ultrasound (key ON/OFF).
Pull the power plug.
Do not place the ultrasonic bath in the sink.
Empty the oscillating tank, to do this
- Ultrasonic baths with outlet
Place ball valve handle in direction of discharge to open outlet.
- Ultrasonic baths without outlet
Pour out tank contents over the (rear left) corner.
In doing so, avoid splashing the ultrasonic bath from below.
After emptying the oscillating tank, thoroughly rinse it. Rub dry with a
soft cloth.
For additional care instructions, see chapter 5.

4.3 Treatment of medical and dental instruments
• The disinfection and cleaning of medical instruments in a single step follows the general
sonication procedure, see chapter 4.2.
• A combined disinfection and cleaning of medical instruments in the ultrasonic bath is only
possible with the use of special preparations (with the corresponding microbiologic certificates).
An ultrasound alone will not disinfect them!
• Only disinfection agents and/or detergents that are non-affixing may be used.
• In terms of concentration, temperature, and sonication time, the manufacturer specifications for
the disinfection agent and/or detergent used are to be strictly adhered to.
• The compatibility between the instrument and the preparation is to be verified on the basis of
the respective manufacturer's specifications.
• The service life of the disinfection solution pursuant to the manufacturer specifications is to be
heeded.
The cleaning solution is to be immediately replaced if contamination is evident. It is to be
replaced, however, at least every work day.
• Prepare instruments appropriately, e.g. by rinsing them with cold water of at least drinking
quality, fully separating / opening them!
Adhere to the instructions of the respective instrument manufacturer.
• Operate the ultrasonic bath with a lid or below and/or atop a suctioning system.
• Further treat instruments after sonication in accordance with KRINKO recommendations/4. In
other countries, the relevant supplementary/divergent national regulations should be taken into
account.
• Adhere to OSHA safety measures (e.g. protective clothing, protective goggles, suitable gloves).
Special case "thorough cleansing"
In the case of stained, crusted or oxidised instruments, a thorough cleansing is recommended.
The thorough cleansing is carried out as indirect sonication in a plastic insert tub, using a special
detergent (see chapter 7.2).
