Powersonics (Benchtop ultrasonic cleaners)
Available from Ultrasonics Depot
Although the industrial stack transducer has been acknowledged as superior in terms of reliability and performance, benchtop cleaners have always relied on wafer-thin discs to produce ultrasonic energy. Crest has brought the superior performance of full-wave 45 kHz Ceramically Enhanced Industrial Transducers to the Benchtop line. What's more, all units are supplied with either 0-30 minute analog or 0-99 minute digital timers and the heaters are thermostatically controlled. If you compare other benchtop cleaners, be sure to compare features because there really is no comparison.
Powersonic™ feature ensures uniform cleaning throughout the tank by sweeping the ultrasonic frequency 3 kHz, creating overlapping ultrasonic waves. This eliminates inconsistent cleaning due hot spots (areas of intense ultrasonic activity) in the cleaning solution, caused by the unvarying or "standing" waves produced by conventional ultrasonic power supplies.
