Yunyisonic YL0304-2840 is a 4.5L capacity dual-frequency ultrasonic cleaner (28/40kHz) built for laboratory workflows involving emulsification, dispersion, extraction, and degas preparation. Equipped with adjustable power up to 150W and a durable SUS304 stainless steel tank, it fits standard beakers (5–400mL) used in chemical analysis, sample prep, and fluid testing.
This model integrates pulse cleaning for strong cavitation bursts — ideal for breaking down emulsions, removing carbon buildup, and dislodging stubborn residues. The degas function offers gentle ON/OFF pulsing (5s cycles) that clears dissolved gases from new solutions, improving ultrasonic transfer efficiency.
Whether you’re running wastewater treatment simulations, algae disruption experiments, or fine powder suspension, the YL0304-2840 offers stability, repeatability, and customizable control — all under a compact, user-friendly design.
Multi-mode Highlight
| Function Mode | Degas Mode | Pulse Mode |
|---|---|---|
| Purpose | Removes dissolved air to enhance cavitation | Enhances power bursts for tough residues |
| Operation | 5s ON / 5s OFF ultrasonic cycle | Continuous ultrasonic with pulsed strength |
| Power Output | Intermittent output, reduced bubble shielding | Full power with dynamic modulation |
| Use Case | Ideal for new solution prep, sensitive extraction | Best for stubborn grease, carbon, emulsions |
| Control | ON/OFF timing-based | 1–100% adjustable pulse intensity |
| Applications | Sample degassing, pre-cleaning, analytical precision | Algae removal, particle breakup, oil degumming |
Application Scenarios
