Cole-parmer provides ultrasonic cleaners. These ultrasonic cleaners transform low frequency ac current into high frequency sound waves [47 khz for 1/2, 3/4, 1-1/2, and 2-1/2-gallon models; and 40 khz for 5-1/2-gallon models] via an el ctroacoustic transducer. Following are some of the technical features of the ultrasonic cleaners:the transducer creates sinusoidal waves, which in turn cause cavitation, the formation and violent collapse of minute vacuum bubbles in the solution;. These implosions thoroughly scrub every surface with which the solution makes contact yet are not harsh on delicate items. Users can choose from five sizes of ultrasonic cleaners. These cleaners all of which are available with mechanical timer, with heater and mechanical timer or with heater digital timer temperature monitor and degas feature. The leak-proof housing features super sealing double o-rings and recessed ventilation are the features which are provided by the leak-proof housing. The 304 stainless steel tank is surrounded by a durable impact resistant polypropylene housing. Sealed membrane control panel is impervious to splashes and spills. Each cleaner is provided r comes complete with polypropylene lid, integral handles, non-skid feet, and a 7-1/2 foot power cord [115 v ac models include plug; 220 v ac models do not include plug]. All models are ul listed and csa certified. For critical cleaning applications choose a cleaner with heater digital timer, temperature monitor, and degas feature. The degas feature eliminates aair bubbles are eliminated by the degas from the solution for more efficient cleaning. The built-in temperature sensor prevents ooverheating is prevented by the built-in temperature sensor and automatically shuts down heating and ultrasonics when solution exceeds 158°-f [70°-c].
