V-bottom design: Our V-bottom design on selected machines makes it easy to clean between batches. V-bottom tanks are also designed to collect particles that fall off in the cleaning process without disturbing transducers and inhibiting their ability to deliver effective cavitation. Many ultrasonic cleaner manufacturers offer only flat-bottom tanks with transducers mounted on the bottom of their machines. This creates fundamental problems. Parts being cleaned should be placed at least 1-2 inches away from the transducers. Yet when you cover the transducers with parts and dirt, the cavitation gets distorted, which mitigates its cleaning power
