Equipment for liquid processing using ultrasonic energy, such as promoting chemical reactions, material dispersion, sterilization, emulsification, and extraction. Fine particle slurries of secondary agglomerates like pigments, ceramics, magnetic powders, and carbon can be crushed, dispersed, and emulsified in containers such as beakers. The ultrasonic output can be continuously adjusted between 10% and 100%, with timer and continuous operation modes, allowing for the setting of ultrasonic irradiation time and interruption time. The size of the horn can be selected based on the volume of the processing liquid, featuring an automatic tuning function that enables automatic oscillation under ** conditions. Its space-saving design makes it highly suitable for use in laboratories.。
