Tovatech’s Elmasonic P series ultrasonic cleaners give users control of ultrasonic power, frequency, mode, time and temperature for a wide range of cleaning tasks. Available in six tank sizes from 0.75-7.5 gallons, the units operate at 37 or 80 kHz in four ultrasonic modes for cleaning, intense cleaning, dissolving and degassing. Delicate instruments can be safely cleaned at 80 kHz. A pulse mode produces periodic sharp spikes in ultrasonic power to create explosions of cavitation activity for dislodging difficult-to-remove contaminants. An intuitive control panel with digital readouts allows users to select ultrasonic power, frequency, mode, time and temperature. A hold button allows temporary removal of samples and resuming the process when ready.
