High Frequency Ultrasonic Cleaning

Megasonic Clearing (HI MEGASONIC)
Suitable for precise cleaning of Si Wafer, GaAS, liquid crystal glass, glass mask, HDD, crystal transducer, thin-film magnetic head, brittle materials and etc.


  • Megasonic cleaner is high frequency ultrasonic cleaner for precise cleaning and suitable for high level cleaning requirements of silicon wafer, flat panel, HDD field that removing ultrafine particles.
  • High frequency (750kHz, 950kHz) megasonic cleaning removes particles by acceleration to realize uniform cleaning and less damages.


  • 0.1W power setting available. Easy cleaning control for less-damage cleaning.
  • Wide range of supply power voltage:AC200~240V +/-10% 50/60Hz
  • Max potput power:1200W for large area cleaning.
