Abstract: The present invention relates to methods for reducing cavitation-induced erosion, staining, and surface degradation of vessels placed in an ultrasonic bath during ultrasonication. Excessive cavitation caused by high ultrasonic power-density leads to white spot formation, micro-pitting, and long-term structural weakening of glass and other vessel materials. The inventors discovered that controlling ultrasonic operating parameters, particularly power-density and bath volume, maintains cavitation intensity within a safe and stable regime while preserving effective dissolution and mixing performance. Experiments demonstrate that maintaining an operational power range of approximately 50–60% of the ultrasonicator’s rated output (which is typically 400 W), corresponding to a power-density preferably in the range 11-14 W/L for borosilicate glass, prevents cavitation-induced white stains even during prolonged exposure. The invention provides a systematic method to regulate ultrasonic energy via power-density adjustment, bath temperature control, and increased liquid volume, thereby extending vessel lifespan and improving reliability of ultrasonication processes across pharmaceutical, chemical, food, electronics, and other industries.
