This submersible ultrasonic probe is a standalone ultrasonic liquid processing unit matched with an independent generator, available in 20kHz, 28kHz and 35kHz frequency options. The generator measures 255×160×100mm with optional power ranging from 500W to 3000W and a net weight of 3kg. Without an integrated tank, the vibrating rod can be directly immersed into users’ existing tanks, reactors and vessels. It delivers efficient ultrasonic cavitation effect to realize liquid dispersion, emulsification, defoaming, active ingredient extraction and cell crushing, widely applicable for chemical, pharmaceutical, laboratory and industrial wastewater treatment processes.
