• Depending on the model, comes with heating (type “H”) or a special oscillating tank (type “C”)

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 releases energy upon imploding and generates 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.

Purpose

General application
SONOREX ultrasonic baths are intended for the sonication of aqueous fluids. They work based on 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. 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:

• during manual treatment
• before machine treatment
• 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.

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.

• 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.
• 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.
• 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.

If any damages or defects are found, these are to be immediately notified in writing to the transportation company and to the supplier. Before startup, the ultrasonic bath is to be left to stand at its operating location for 2 hours so that it may adapt to the ambient conditions.

Scope of delivery

• 1 Ultrasonic bath, optionally with heating – see delivery note
• 1 Ball valve (brass, galvanized) with hose, as of type RK 102 H, packaged separately with sealing tape and assembly instructions
• 1 Instruction manual

Additional accessories according to order – see delivery note

Set-up/assembly

• Place the ultrasonic bath atop a firm, level and dry surface. In doing so
  • observe the maximum weight of the ultrasonic bath, including fluid. For net weight.
  • do not block the air supply below the ultrasonic bath.
  • guard against moisture and wetness – the risk of electric shock.
• In the case of ultrasonic baths with a drain outlet, mount the ball valve, hose socket and hose, which are included in the delivery, under the enclosed assembly instructions.

Start-up

• Thoroughly rinse the ultrasonic bath’s oscillating tank with water before its first use.
• Verify that the control buttons are in the “off” position, i.e. the switch indicator above or the toggle switch is set to “0”, then connect the ultrasonic bath to the mains (grounded socket).
• Conduct function test – briefly plug in the ultrasound (maximum of 1 to 2 seconds), a hissing noise should be heard. Set to “0” once again.
• It is recommended that a foil test be conducted as part of quality assurance before the first use. This test is to be saved for later comparison, see appendix for information.
• If applicable, hang accessories in the ultrasonic bath and place the lid on top.

Operation

Operating elements

The ultrasound and the heating system are operated from the front:

1. Toggle switch for heating ON / OFF incl. control light (only type “RK 31 H”)
2. Turning knob for heating ON / OFF incl. adjustment control (only as of type “RK 52 H”)
3. Turning the knob for ultrasound ON / OFF with the preset time
4. White control light (the heating system is activated)
5. Yellow control light (heating system in operation – from RK 100 H)
6. Green control light (ultrasound in operation)

The layout of the control lights depends upon the ultrasonic bath.

Ultrasound
The ultrasound is operated through the turning knob (time switch).

Timed operation:

• Turn the knob to the right range of time 1 – 15 minutes
  • Green control light flashes.
  • Once the time has elapsed, the time switch will automatically turn off.
• By turning the knob back, the operating time will be shortened, i. e. the ultrasonic bath will be turned off.

Continuous operation:

• Turn the knob to the left
  Setting ∞

  • Green control light flashes.
  • The ultrasonic bath will not turn off automatically, to switch it off turn the knob left, back to “0”.

Notes

• While turned off, the ultrasonic bath may remain connected to the mains.
  It can be disconnected from the mains by pulling the mains plug.

• An “engaging” of the time switch is barely felt if the mains voltage is not present, e. g. if the mains plug is disconnected or the fuse is blown.
  The time switch only works if the mains voltage is present.

Heating
The heating system is operated through the integrated toggle switch or turning knob.

• Switch on the toggle switch
  Fixed setting 65 °C

  • The yellow control light in the switch will flash.
  • Press the switch to turn it off (a “0” becomes visible)

If a bath temperature of approx. 65 °C is reached, and the heating will turn off – the control light will continue to flash.

• Turn the knob to the right
  Temperature range 30-80 °C:

  • To turn it off, turn the knob left back to “°C”.

  • RK 52 H (a white lamp):
    The white control lamp comes on during the heating phase and goes out when the set temperature is reached.

  • From RK 100 H:

  • The yellow and white control lights will flash.

  • The yellow control light goes out when the set temperature is reached.

Notes

• The heating system works independently from the ultrasound.
• The heating will automatically turn on every time that the bath temperature drops below the set temperature.
• 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.

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: Inset beaker

• 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.

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 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.

General use

Step 1: Fill the oscillating tank
The oscillating tank is filled with water and a suitable preparation to reduce the surface tension.

Direct sonication

• Fill 1/3 of the oscillating tank with water.
• Add dosed preparation to the oscillating tank. See the appendix for dosage information.
• Fill carefully up to the filling level mark, and 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 the oscillating tank with water.
• Surfactant.
• Fill carefully, and 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 time must be degassed before use.

• Remove the basket and other accessories from the oscillating tank.
• Place lid on top.
• For degassing, start the ultrasound with the turning knob.
  • up to 10 litres bath volume: 10 min
  • more than 10 litres bath volume: 30 min

Time needs 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 the basket and other accessories from the oscillating tank.
• Place lid on top.
• Using the turning knob, set the desired temperature.
• 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 – the 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.
• The 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.
• 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.
• 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 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 respective used preparation.
• In the case of stubborn residue, conduct sonication for a longer time if necessary.
  • Place lid on top.
  • Using the turning knob, set the desired sonication time.

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 it 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 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.

• Switch off ultrasound.
• 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 the ball valve handle in the direction of discharge to open the 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.

Treatment of medical and dental instruments

• The disinfection and cleaning of medical instruments in a single step follows the general sonication procedure.
• 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 based on the respective manufacturer’s specifications.
• The service life of the disinfection solution under the manufacturer’s 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, and 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 by KRINKO/4 recommendations. 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.

Further information

Degassing

• Degassing the sonication fluid increases the ultrasound effect.
• Freshly filled-in fluid or fluid that has remained in the oscillating tank for a longer period must be degassed before 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, and 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.

Disposal of sonication fluids
The working solution is disposed of under the specifications in the product leaflet and the label supplied by the manufacturer of the preparations employed. All aqueous preparations made by DR H. STAMM GmbH are prepared under the regulations of the German Washing and Cleansing Agents Act, are biodegradable and as working solutions may be disposed of in the wastewater. Strongly acidic and strongly alkaline fluids are to be previously neutralised under technical data sheet specifications. The manufacturer’s specifications for the respective preparations should be observed. During cleaning, materials hazardous to water such as oils, heavy metal compounds, etc., depending on the type of contamination, may enter the working solution. If the limit values are exceeded, the working solution must be reconditioned (removal of contaminants) or disposed of as toxic waste.

Disinfection and cleaning agents that become contaminated when used are considered “waste material” according to the German Waste Act (AbfG) and may not be taken back by the manufacturer. In other countries, the relevant supplementary/divergent national regulations should be taken into account. In every case, the statutory provisions and regulations of municipal wastewater plants must be adhered to. Information is provided by municipal wastewater plants as well as by environmental agencies.

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.
• No guarantee will apply to damage caused by the use of unsuitable surface disinfection agents or detergents.

Cleaning and care

Oscillating tank
The oscillating tank of an ultrasonic bath is a worn 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

• Thoroughly and frequently rinse the oscillating tank with water and rub 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.
• Metal particles that remain on the stainless steel surface as well as rust particles from the water pipe system penetrate the passive protective layer of the stainless steel. The stainless steel is “activated” in this process and it begins to rust. The extraneous rust produces localised corrosion of the stainless steel. For this reason, remove metal parts such as screws, filings, etc. from the oscillating tank, and immediately remove rust stains using a soft cloth and a commercial stainless steel cleaning product without abrasive additives.

Housing

• Do not use any abrasive cleaners, only commercial care products without abrasive additives.
• Housing is to be wiped off only from the outside with a moist cloth; afterwards, allow to dry alone or wipe dry.

Disinfection for medical applications
If contaminated medical instruments are treated in the ultrasonic bath, hygienic safety after the application is important. To avoid any cross- contamination as a result of the colonisation of microorganisms, especially along the tank edge and in the drain outlet area, but also on the operator panel, these areas are to be regularly cleaned and disinfected with a suitable surface disinfectant, i.e. one that is at least bactericidal, pesticidal and virucidal against enveloped viruses. Accessories such as holders and baskets should be processed regularly in a cleaning and disinfection unit.

Warehousing/storing
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 to protect the oscillating tank from outside contamination.

Maintenance and repair

Maintenance

• SONOREX ultrasonic baths require no maintenance.
• For purposes of regular control, the following functional checks may be carried out.

Functional checks

Checking control lights

Checking the ultrasound and/or heating
The function can be checked using a standard wattmeter. It is to be inserted between the ultrasonic bath’s power plug and the power outlet.

• Fill the oscillating tank with fluid.
• For testing purposes, only the ultrasound or the heating system is to be plugged in. Next, the value displayed is to be compared with the corresponding value in the technical data (tolerances ± 20 %).

Checking the ultrasound effect

• For this check, it is recommended that a foil test be conducted.
• A suitable frame for a foil test can be requested from the manufacturer. Customary aluminium foil is used to conduct the test. Next, a comparison is made with previously generated foils. For more detailed information, please see the appendix.
• A measurement procedure is described in DIN SPEC 40170:2013-11 (Measurement and judgement of the cavitation noise).

Error analysis
SONOREX ultrasonic baths are robustly constructed and designed for a high level of reliability. Nevertheless, the possibility of a malfunction due to a defective component can never be fully discounted. The following overview of possible sources of error should serve as an aid for error detection and elimination.

• Ultrasonic bath oscillates weakly, unevenly, or the noise is too loud:

  • Has fluid been properly degassed? Sonicate for 15 min.
  • Is it overloaded with objects to be treated? Remove a few parts.
  • Uneven noises (wobbling) No error – slightly adjust the filling level of the fluid.

• Heating system defective?
  The ultrasonic bath can be readily operated without heating.

• Emergence of light erosion on the bottom of the tank?

  • Natural wear.
  • The ultrasonic bath is OK.

Any malfunctions are to be communicated in writing to the manufacturer.

Repairs and service

CAUTION!
Repair work may only be carried out by authorised, qualified personnel or by the manufacturer. The manufacturer assumes no liability for unauthorised interventions on the ultrasonic bath!

If errors or defects are ascertained as a result of the functional check, and if it is impossible to rectify such errors, the ultrasonic bath may no longer be used. In such a case, please contact the local distributor or the manufacturer:

Foil test

Information

Foil test
Testing of ultrasonic baths

A foil test1 is recommended for testing ultrasonic baths. It is to be conducted upon initial startup, and at regular intervals thereafter (e.g. every 3 months). The frequency of testing is the responsibility of the user. The foil test is a simple procedure to demonstrate the intensity and distribution of cavitation in an ultrasonic bath. To do so, aluminium foil is stretched over a foil test frame. It is perforated or destroyed to a certain degree by cavitation, depending on the duration.

For purposes of reproducibility, the test conditions must remain constant:

• Fill level in the oscillating tank (²/3)

• Temperature of tank contents

• Degassing time, if needed (degassing 5 to 30 min. before the test, depending on the tank contents)
  Time may need to be extended with acidic cleaning solutions.

• Frame positioning

• Foil properties (thickness, surface)

• Sonication time

• Concentration and type of ultrasound preparation

Foils can be archived in a suitable way (scanning, photos, etc.) This allows the foils to be compared at any time. The perforated areas of all foils should have approx. the same dimensions and distribution – the results are never identical. Process validation, e.g. for the treatment of medical products, can only be achieved by conducting regular foil tests.

To execute the foil test, different foil test frames FT can be ordered from the manufacturer (for a fee). The foil test frames are suitable for a wide range of tank dimensions. Aluminium household foil is also required to conduct the test and is not included in the delivery. Film: http://bandelin.com/folientest/.

Fluid for the foil test
To obtain an adequately strong cavitation effect, the surface tension of the water used must also be reduced for the foil test with the help of surfactant preparations. We recommend the following ultrasound preparations:
STAMMOPUR DR 8, STAMMOPUR R, TICKOMED 1, TICKOPUR R 33, TICKOPUR R 30, TICKOPUR TR 7

If none of these preparations is available, a neutral or mildly alkaline preparation that does not destroy aluminium may be used. The preparation must be approved by the manufacturer for use in ultrasonic baths.

Conducting the foil test

1. Fill 2/3 of the oscillating tank with water and a suitable ultrasound preparation in the dosage specified by the man-ufacturer.
2. Degas the liquid: < 10 l – 10 min and > 10 l – 30 min (see user instructions.)
3. Stretch aluminium foil (household foil with a thickness of 10 µm to 25 µm) over the wireframe (stainless steel). Depending on the tank size, the frame may protrude from the tank. Covering the portion of the frame that is submerged will suffice.
4. With the ultrasound switched off, place the foil-wrapped wire frame diagonally inside the oscillating tank, and adjust if necessary.
5. Switch on the ultrasound and sonicate the foil for at least one minute until visible perforations or holes are produced. With sturdier foils (thicker or coated ones), the sonication time can last up to 3 minutes.
6. Switch off the ultrasound, take the foil out and let it dry.
7. The foil must be perforated, otherwise, contact the manu-facturer.
8. Archive it together with the testing date and the serial number of the ultrasonic bath.
9. After the test, the oscillating tank must be thoroughly rinsed out to remove any loose foil particles.
