Below are typical lab use cases of ultrasonic cleaning: from dispersing emulsions to cleaning optics and micro parts in glass beakers.

Ultrasonic Frequency Range and Application Guide

Frequency Range: 17kHz–28kHz
With longer wavelengths, low-frequency ultrasonic waves generate large but uneven cavitation bubbles. The collapse of these bubbles produces significant force, making it ideal for:

• 20kHz–25kHz: Assisting experiments such as wastewater treatment, algae inhibition and removal, dispersion of large-particle powders, emulsion extraction, and the treatment of hard-to-degrade organic substances.
• 28kHz: Best suited for rough cleaning tasks, especially heavy-duty applications like removing heavy oils, rust, and stubborn stains.

Frequency Range: 33kHz–40kHz
Moderate wavelengths generate a balanced number of cavitation bubbles and moderate collapse force. This makes medium-frequency ultrasonic waves suitable for:

• Standard cleaning tasks and routine laboratory experiments, including promoting fusion, catalysis, powder dispersion, and cleaning regular laboratory glassware.
• 40kHz: Known as the general-purpose ultrasonic frequency, ideal for multi-functional like household, commercial.

Frequency Range: 68kHz–200kHz
Shorter wavelengths generate dense and uniform cavitation bubbles. The collapse of these bubbles delivers gentle force, creating a refined ultrasonic field ideal for delicate and high-precision tasks:

• 68kHz–80kHz: Suitable for cleaning complex parts, as small cavitation bubbles penetrate micro- to nano-sized blind holes, removing contaminants or dust.
• 120kHz–200kHz: Preferred for precision cleaning in micro- and nanofabrication. Applications include:
  • Cleaning micron and nano-sized blind holes and through-holes.
  • Assisting in dispersing micro- to nanoscale particles.
  • Extracting intracellular substances.
  • Catalyzing the synthesis of new materials.
  • Removing particles from precision optical components and highly sensitive parts like wafers.
