50W 40khz Stainless Steel Mini Ultrasonic Cleaner Bath 2L With Digital Timer

We know that your reputation depends on cleaning parts effectively and efficiently. Ultrasonics International can help you choose the right kind of ultrasonic cleaner for your motorcycle industry needs.

For more than two decades, Ultrasonics International has helped businesses improve profitability by providing their clients with ultrasonic cleaning equipment that feature the latest advancements in wave sweep technology. Our ultrasonic cleaning equipment has a reputation for reliability and longevity. Utilizing the proper ultrasonic cleaning equipment saves money and improves cleaning processes. Cleaning results will be measurably better and less time will be required to complete the cleaning process. Production numbers go up and labor hours go down dramatically because multiple parts can be addressed simultaneously.

You’ll also need to know the working depth of the cleaning fluid as it relates to the size of parts you’re cleaning.

The working depth is the distance from the inside bottom surface of the basket to the surface of the liquid in a filled tank. This is important because parts being cleaned must be fully immersed in the liquid.

Sample prep, on the other hand, may require less depth because the entire container need not be immersed in the solution. Special units are designed for sample prep operations.Product specs for benchtop ultrasonic cleaners may not include this information. If they do not, feel free to contact the manufacturer or supplier for this information. On the other hand manufacturers of large industrial tanks often report both tank depth and working depth.For more on this see our video on selecting tank size.

2. How are you using the equipment?

Ultrasonic cleaners do a lot more than clean parts such as gears, carburetors, PCB boards and surgical instruments. In the lab they are broadly employed to degas solvents, disperse nanoparticles, and emulsify, dissolve, disperse and otherwise prepare lab samples.

If you are cleaning parts, to get started you need to consider the following before making a selection:
Type of contamination to be removed. There’s a big difference, as you can imagine, between removing coolant from machined parts, varnish deposits from a carburetor, ink from printing rolls, and blood and tissue residues from surgical instruments.
The composition of products being cleaned. Different parameters apply to cleaning aircraft engine components and glass capillaries. You’ll need compatible cleaning solution and ultrasonic cleaning frequency.

Will you be cleaning batches or individual parts?
Component size and weight
Once you define exactly what you’re trying to accomplish the following points will help narrow down your equipment selection. Then it’s time to contact Tovatech for specific recommendations.

3. Add Baskets to your Spec Sheet
Basket

Baskets support parts and sample containers in an ultrasonic cleaner.

They affect cleaning and sample processing efficiency and, importantly, protect tanks from damage. Baskets with insulated handles facilitate placing and removing parts being cleaned in hot liquid. They also keep parts, flasks and beakers off the tank bottom where they suppress vibration and lower cleaning effectiveness. In terms of tank life, keep in mind that the bottom of the tank is a vibrating membrane. Any solid item, particularly a metal part, can act as a drill while the ultrasound is operating. Over time this can wear a hole in the tank. That’s a good enough reason to use baskets.

Some baskets hang on the tank rim;

others are equipped with rubber coated feet positioned near the corners of the tank bottom where vibration is at a minimum.

Fine mesh baskets for small parts can be positioned in beakers or standard baskets.

You’ll find a bit more on this in our post on ultrasonic cleaner basket specification. This post connects to a related post for additional background.

4. How to Specify Ultrasonic FrequencyUltrasonic frequency is produced by generator-powered transducers bonded to the bottom of the tank. They vibrate in kilohertz (kHz or thousands of cycles per second) above the hearing range, which is approximately 20 kHz.Most ultrasonic cleaners operate between 35 and 45 kHz. This frequency range is well suited to the vast majority of cleaning tasks. Sample prep is often accomplished with units operating at 37 kHz. An example of an ultrasonic unit especially designed for sample prep is microprocessor-controlled

A lower frequency such as 25 kHz produces larger cavitation bubbles.

When these bubbles implode they release a larger amount of cleaning energy. For coarse cleaning such as removal of lapping abrasives or polishing paste, a lower frequency will be more effective. Note that the lower the frequency, the louder the cleaning operation. Sound-deadening tank lids with insulation are a good idea when operating at 25 kHz. Another useful accessory is a noise-protection box in which to place the unit.

A higher frequency produces smaller cavitation bubbles.

These cover fine featured complex surfaces more thoroughly and are gentler than low frequencies.

For fine cleaning of very delicate jewelry, electronics, and soft metals with polished surfaces consider a unit operating at 80 – 130 kHz.

If you are cleaning capillary tubes or spectrophotometer cuvettes you will need a unit that operates at 80 kHz or higher.If you are cleaning a variety of materials consider a dual frequency ultrasonic cleaner.
