There can be many frequencies used in anultrasonic cleaner with basket,It comes down to what you’re trying to clean, and how you’re trying to clean it. Some of the most common frequencies include:
25 kHz
A 25 kHz generator is used with larger mass items, such has a large cast iron block used for injection molding, a massive steel cutting tool or large stainless steel plates. It works best when the contaminant is on the surface of the item and requires a little more punch to remove it. This frequency also works well for removing baked on materials and is often found on plating lines for pre-treatment prior to the plating process. Larger tanks often are retrofitted with 25 kHz systems for these types of jobs.

40 kHz
The vast majority of ultrasonic cleaning applications require the mid-sized cavitation bubbles created by a 40 kHz generator. Approximately 90 percent of all ultrasonic cleaning applications can be addressed at this frequency. It has enough power to shake contaminants loose but is small enough to penetrate closer to the substrate. This frequency works best when items have many through-holes and/or complicated blind holes that are difficult to reach using the larger cavitation bubbles generated at lower frequencies.
Typical applications of 40 kHz generators include carburetor cleaning, removing oils and metal chips from general machine shop applications, soot removal from items damaged in fires, cleaning of ceramics used in the high technology fields, removal of biological contaminants from surgical tools and many more.

What can be cleaned in an ultrasonic cleaner?
Ultrasonic cleaner can be used to clean gold and silver, jewelry, glasses, teeth, bicycle chains, auto parts, electronics, medical equipment, collectibles, etc.
In an ultrasonic cleaner, the object to be cleaned is placed in a chamber containing a suitable solution (in an aqueous or organic solvent, depending on the application). In aqueous cleaners, surfactants (eg, laundry detergent) are often added to permit dissolution Of non-polar compounds such as oils and greases.
