Ultrasonic baths: review, characteristics, how to do it yourself

From Masterweb

To date ultrasonic bath actively used for cleaning a variety of things. In addition, it is successfully used both in everyday life and in industrial scale. Its use made it possible to significantly speed up and improve the cleaning procedure.

What is a device

Ultrasonic bath is a container small sizes, which uses ultrasonic waves during its operation. Such waves are too weak for human hearing to detect, but they are quite capable of successfully combating different types dirt and even rust. Due to the influence of ultrasound, small air bubbles will form inside the container. Their number will increase and they will collide with each other. The result of the collision is a small impact, the force of which is sufficient to push dirt off the surface of the part.

As for the container, its size depends on what parts it is designed to work with. This parameter ranges from 0.5 to 30 liters.

Operating principle and design elements

In order to use an ultrasonic bath correctly, it is important to know how it works. For the operation of the equipment, a liquid is required, which includes alcohol, another substance of chemical origin, as well as active and ordinary water.

After filling the container with such liquid, the part is placed inside. Cleaning time is usually 2-3 minutes, but can increase if the part is covered with too much dirt, for example.

Typically, this structure is assembled from stainless steel. The basis of an ultrasonic cleaning bath consists of the following three elements:

• The first element is the emitter. The main function of this device is the conversion of electrical vibrations that are created under the influence of ultrasound. The type of such vibrations is mechanical, and they are transmitted to the liquid through the walls of the container.
• To create vibration, the bathtub design always includes a generator.
• The last element is a heater that will constantly maintain the temperature of the liquid in the bath. The maintained temperature is usually 70 degrees.

It is worth saying that the heater is not necessary, and there are models that function without it. However, its presence significantly improves the performance of the device.

Scope of application

The scope of application of such equipment is quite wide. It is successfully used for cleaning not only various types of parts, but also tools, for example. The main areas of application of such devices are mechanical engineering, medicine, electronics, and cosmetology. However, this is a general and fairly short list. Most often, units are used for the following purposes:

• Using an ultrasonic bath for injectors is one of the most common applications. Although it is worth saying that such a procedure is usually only possible at a service station.
• The use of the device in the electronics industry has become quite popular, where it is used to clean small parts from tablets, phones, laptops and other things. These devices have rather small spare parts, which are sometimes simply impossible to clean manually. Baths of this type completely solve this problem.

Positive and negative aspects of use

Ultrasonic bath Clean, like other models from different manufacturers, has a number of specific advantages:

• fairly high time savings, since cleaning the part takes an average of about 5 minutes;
• ultrasonic waves penetrate even the most inaccessible places, which is great for cleaning parts with complex shapes;
• since during operation no mechanical impact on the part, then scratches and other defects will never appear on it;
• Naturally, to clean parts in this way you do not have to make any physical effort, which is quite important, especially on an industrial scale;
• In addition to cleaning, the machine also does a good job of polishing, which will help in some cases or return original appearance, or even improve it.

However, there were some negative aspects:

• Such products are quite difficult to find. On the territory Russian Federation purchasing such devices is difficult because they are not very common, and therefore you have to spend a lot of time to find a product that will have good reviews and the required characteristics.
• Price. Such a device has enough high price, which varies from 20,000 to 40,000 thousand rubles. In the industrial sphere, this is not too much money, but it will definitely pay off, but as for domestic use, it is better to make an ultrasonic bath with your own hands.

Assembly materials

In order to make such a device with your own hands, you will need the following list of parts:

• a container or frame made of stainless steel, which will serve to immerse parts;
• a small tube made of glass or durable plastic;
• pump for pumping liquid into a container;
• a round magnet that can be removed, for example, from an old model of speakers;
• you will need a coil whose rod is made of ferrite;
• you will need another small vessel made of porcelain or ceramics;
• last necessary element- This is a pulse type transformer.

You will also need to buy the liquid that will be used for the job.

Where to start assembling

When everyone is ready necessary tools, you can start assembling the ultrasonic bath with your own hands.

The assembly process begins with the coil being wound onto a glass or plastic rod. It is important to note here that the ferrite rod of the coil itself should hang freely; there is no need to fix it. You will need to attach a magnet to the end of the rod. The result of such manipulations should be a magnetostrictive transducer or a homemade emitter.

Bathtub assembly

You need to drill several holes in a ceramic or porcelain vessel. They will be used to insert a previously prepared emitter. After this, you can fix the vessel in the container. Then you should start fixing the pipes for supplying and draining the cleaning liquid. It is worth noting here that the fluid supply can be improved if the pump is of a built-in type.

Pulse transformer in in this case will ensure more efficient operation of the unit when the voltage rises. Such devices are available in finished form in old TVs or computers. Once all the elements are in place, you can conduct a test run.

However, before you launch it, you need to pay attention to the following details:

• you need to make sure that there is no external damage;
• You cannot use a bath without liquid, as this will most likely lead to the destruction of the rod;
• It is strictly prohibited to touch the parts located inside the container with your hands during the cleaning process.

In addition, when operating the device, it is very important to observe simple rules fire and electrical safety.

Domestic models

For those who decide to buy this equipment, and not doing it yourself, there will be difficulties, which lie in choice. There are many companies and many different models, which makes it quite difficult to choose the right one for the first time. Therefore we can give brief overview some domestic companies:

1. Ultrasonic baths "Grad" are most often used on an industrial scale, and therefore are not suitable for private use.
2. Sapphire devices can be used to clean almost any part.
3. There is a company called "Gals", which is famous for the fact that its devices, made of stainless steel, perfectly clean the most difficult places.
4. If you need a device for use in the field of dentistry, then the company "UZV Raltek" has proven itself excellently.

How to choose correctly

When you need to choose such a device, you need to know several important criteria.

Firstly, you definitely need to decide why it is needed. The answer to this question will determine what capacity the device should have, and its cost directly depends on this. Secondly, you should pay attention to the presence of such a part as a heating element. Its presence will help significantly improve the quality of work, but will also increase its cost. Some models are equipped with a timer for convenience. The cost of the unit will increase slightly, but this will significantly help in its operation.

Codyson device

The Codyson CD-4810 ultrasonic bath, for example, is widely known in cosmetology. The main task of the device is to clean manicure attachments and tools. In addition, it can be used to perfectly clean other hand tools who have complex shape or moving parts, such as scissors. The main characteristic for all units is vibration frequency, which determines the degree of cleaning. For this manufacturer, this parameter is 35 kHz. This is quite enough for the waves to cope with the cleansing of even hard-to-reach places.

Models from this company have a timer, the range of which varies from 1 to 30 minutes. It is located on the front panel, but it is protected from moisture and chemicals, which allows you not to worry about its failure due to the ingress of these substances. The material for making the bathtub in this case is high-quality plastic, and the cleaning tank itself is made of stainless steel. The volume of this model is 2 liters. This is quite enough for use in the field of cosmetology. It can be added that the bathtub is additionally equipped heating element made of ceramics, which has double protection and also a degassing function.

Brief technical parameters devices are as follows:

• weight is 2.2 kg;
• total power 230 W (70 W is the power of the emitter, and 160 is the power of the heater);
• The maximum heating temperature during operation is 60 degrees Celsius.

Simple cleaning of the phone after water costs 800-1000 rubles.
If cleaning doesn’t help and you need to restore contacts and elements, we’ll do it!

Now let's figure out what it is to clean your phone after using water in an ultrasonic bath?

The procedure uses a special device called an ultrasonic bath and special solution, which in the best possible way proved himself in this work.

When the bathtub filled with the solution is running, it looks like a glass of lemonade - it fizzes and bubbles. The supplied pulse creates bubbles that permanently rid the phone board of dirt, oxides, corrosion, organic deposits and other things that shouldn’t be there

What are the stages of cleaning a phone in an ultrasonic bath? Even people who are very far from technology most likely understand that not the entire device is dipped into a bath of solution, but only part of it - the motherboard.

• First and main stage Cleaning a phone using ultrasound means disassembling the device and soldering/removing it from motherboard those elements (for example, microphones, shields) that cannot be immersed in the solution.
• The second step is to immerse the board in the solution. The board cleaning procedure lasts 10-15 minutes. At the discretion of the engineer, the cycle can be extended or repeated.
• At the third stage, the motherboard...is washed. Yes, yes, the solution must be washed off.
• It is logical that the fourth stage will be drying the phone.

At this time, the technician examines other components of the phone - display, cables, body parts. And it carries out mechanical cleaning, because the water that got inside caused damage to other parts on its way to the heart of the device.

• At the final stage, what was soldered in preparation for cleaning is soldered onto the dried board, the device is assembled, and undergoes a final user test. If everything is in order, then it is ready to be issued to the client.

This is the ideal ultrasonic cleaning scenario. But things don’t always happen this way. Why?

Pitfalls and difficulties that arise after ultrasonic cleaning are a consequence of the fact that water is not only a source of life, but also a great danger. Once in the device, contrary to belief, it does not dry out, does not evaporate, and even rice is not a hindrance to it. Water falling on electrical components, turns into oxides that disrupt contact and can also lead to short circuits. However, these oxides remain conductive. Thus, as long as the oxides are in place, the contact is at least maintained.

But after ultrasonic cleaning, the oxides, and along with it the established contact, disappear. This is why there are so many cases when a phone becomes “worse” after ultrasonic cleaning than before.

This is where the main work of the masters begins: finding the lost contact, which sometimes lasts a long time, and restoring it.

This contact may be lost over time, after the client has taken away the working device. Again, for the same reasons - the conductive oxides were gone, the contact somehow remained “on what was left,” and this did not lead to anything good. And the technicians will again put the device to work and look for the lost contact.

Of course, these are not ordinary cases. This happens when the oxides are outdated, and also when the device was actively used after water - charged and connected to a computer. That's why it's so important that you get your phones repaired in a timely manner after water damage! Ingress of caustic liquids, such as sea water, also complicates the work.

From all of the above, it follows that it can be difficult for the service to say exactly how long cleaning will take after water. It can also be difficult for us to say the exact cost of the planned work. And yes, it can be difficult for us to provide a guarantee for the work performed.

A qualified master will always point you to possible risks at work, having carried out preliminary diagnostics.

Now you know that cleaning in an ultrasonic bath requires the qualifications of an engineer. Clean the chain in the bath and mobile phone- these are not comparable things.

Remember, if your phone gets into water, the only thing you can do to help it is to turn off the power and take it to a service center.

A phone that has fallen into water must not:

• dry on radiator
• blow dry

And yes, it is useless to dry a phone that has fallen into water in rice; you are simply wasting precious time.

In fact, everything is very simple - pour the cleaning liquid inside the ultrasonic bath, prepare the dirty instruments and place them inside. You should use the device only after you have read the instructions, as there may be contraindications and special methods of operation.


Typically, cleaning time lasts from 5 to 10 minutes, but if the part is more prominent and heavily soiled, it may take longer. Some baths have the ability to change the operating frequency of the generator, and this will allow for better cleaning various types tools. After all, to cleanse small and prominent things, you need a higher frequency.


It's all about physical phenomenon cavitation, which creates small bubbles of liquids that, during ultrasonic radiation, begin to burst and thereby destroy dirt. As the frequency increases, the distance between these bubbles decreases!


Remember that use ultrasonic cleaning does not completely sterilize instruments. It only removes clots of dirt. If you need complete sterilization, you must use a separate sterilization device, which can be microwave or radiation based.
