Elmasonic S Heated Ultrasonic Cleaner with 3 Modes and High Power. The Elmasonic S ultrasonic bath operates at 37 kHz in three ultrasonic modes: Normal, Sweep, and Degas. Sweep mode produces a continuous slight variation of frequency to provide uniform and thorough cleaning of parts. Samples are rapidly mixed, dispersed, dissolved, or homogenized in Normal mode. A series of LEDs continuously show set time, time remaining, set temperature, and actual temperature. No need to scroll through menus to view parameters. The microprocessor-controlled generator in this sonic cleaner maintains constant ultrasonic power, sensing and adjusting for light or heavy loads in the tank. Digital operation with power tracking ensures reproducible performance from run to run. Temperature is adjustable from 30°C to 80°C; the timer can be set from 1-30 minutes or continuous operation. The unit turns off automatically after 12 hours of continuous operation for safety. The tank cover can be flipped over and used as a drip tray. The front panel has a convenient LED display of set and actual temperature and time.
