3. Frequently Asked Questions

Q1. How does ultrasonic cleaning work?

Ultrasonic waves at 40 kHz generate microscopic cavitation bubbles in the liquid. When these bubbles collapse, they produce high-velocity micro-jets that dislodge contaminants from surfaces, even in blind holes and crevices.

Q2. How should I prepare the cleaner before use?

Fill the tank with water or a recommended ultrasonic detergent, ensuring the fluid covers your items but stays below the MAX level.

To degas, run the unit empty for 3–5 minutes; this removes dissolved gases for more effective cavitation. Then drain and refill before cleaning your samples.

Q3. What is the recommended cleaning time?

Light to moderate soiling: 3–10 minutes.

Stubborn deposits: up to 30 minutes or multiple shorter cycles.

Set the time using the ▲/▼ buttons on the control panel; the display counts down once ultrasound starts.

Q4. Do I need to use the heater?

Heating (20–60 °C) speeds removal of oils, greases, and organics.

For heat-sensitive samples (plastics, electronics), operate at room temperature to prevent damage.

Q5. What accessories are available?

Stainless steel basket: prevents direct contact with the bottom, protecting the transducer.

Lid: reduces evaporation, minimizes noise, and maintains temperature.

Drain valve: allows easy fluid removal without tilting the unit.

Q6. Can I use organic solvents directly in the tank?

No. Do not pour flammable solvents (e.g., acetone, alcohol) into the tank. If solvent cleaning is required, place the solvent in a sealed container and immerse it in the water bath, never add it directly to the tank.

Q7. How do I maintain and clean the unit?

After each use: power off, drain the solution, rinse with clean water, and dry thoroughly.

Replace cleaning solution every 3–5 uses or when it becomes discolored.

Inspect O-rings, gaskets, and the drain valve for wear; replace if leaking.

Q8. What if the cleaner does not operate?

No ultrasound: check the power cord, fuse, and main switch.

No heating: verify the heating element and thermostat.

Excessive vibration or noise: ensure samples aren’t touching the tank walls or bottom.

4. Safety & Best Practices

Always use a grounded outlet.

Never run the cleaner without liquid (dry run damages the transducer).

Keep hands and loose objects away from the liquid surface during operation.

Follow lab safety guidelines when handling detergents and hot fluids.
