The formation of free iodine from the KI/CCl4 chemical dosimeter has been used to quantify the amount of cavitational activity occurring within a 25 kHz cleaning bath under various exposure conditions. The amount of activity occurring within the bath was related to the supply voltage to the cleaning bath, the time of exposure and the volume of solution. An important observation was that the amount of cavitational activity occurring within a glass beaker suspended within a water-filled bath varied by as much as a factor of ten if that beaker contained different volumes of the test solution. Also, the amount of cavitation occurring within the exposure vessel and its contents of an ultrasonic cleaning bath will assist in the cleaning of dental instruments and their accessories.
碘化钾/四氯化碳化学剂量计中游离碘的形成已被用于量化在各种暴露条件下25 kHz清洗槽内发生的空化活动量。槽内发生的活动量与清洗槽的供电电压、暴露时间和溶液体积有关。一个重要的观察结果是，如果玻璃烧杯中装有不同体积的测试溶液，悬浮在充满水的槽内的玻璃烧杯内发生的空化活动量变化高达十倍。此外，超声清洗槽的暴露容器及其内容物中发生的空化量将有助于清洁牙科器械及其附件。
