30L Dual Frequency Dental Lab Ultrasonic Cleaner | 28/40kHz Large Sonicator Bath with Variable Power

The K1030HTDS 30-liter dental lab ultrasonic cleaner is the largest benchtop dual-frequency sonicator bath with variable ultrasonic power in our entire product line. It delivers 600W of adjustable ultrasonic power and 1000W of heating into a 30-liter ultrasonic bath with genuine 28/40kHz switching. It is a kind of variable frequency ultrasonic cleaner built for dental laboratories, hospital sterile supply departments, and research facilities that process high volumes of instruments and equipment daily. The dual frequency capability means the same bath handles the heavy-duty cleaning of stainless steel trays at 28kHz and the delicate processing of precision instruments at 40kHz—all with the adjustable power and sweep frequency that ensure uniform results across the full 30L volume sonicator bath.

The user can easily switch between the 28KHz frequency and the 40KHz frequency as needed. It can be a professional lab equipment ultrasonic cleaner for lab instruments cleaning, and also for laboratory sonication and degassing use.

• 30L Ultrasonic Cleaning Tank (500x300x200mm) — 200mm depth for tall items; 500mm length for instrument trays and elongated equipment.
• True 28/40kHz Dual Frequency — Selectable output with genuine cavitation at both frequencies; the largest dual frequency benchtop bath available.
• 600W Ultrasonic Power (5–100% Adjustable) — Maximum output in the dual frequency series; adequate cavitation density for the 30L working volume.
• 1000W Heater (0–100°C) — Highest heating capacity in the benchtop range for sustained high-temperature operation.
• Automatic Sweep Frequency — Essential in a 30L tank; prevents the pronounced standing wave dead zones that large fixed-frequency baths suffer from.

• 28kHz – Heavy-Duty Processing — Stainless steel instrument trays, large retractors, and robust surgical instruments with baked-on bioburden.
• 40kHz – Precision & Delicate Work — Dental prosthetics, crown and bridge frameworks, handpieces, and microsurgical instruments.
• Dental Laboratories — Bulk processing of prosthetic components, model holders, and laboratory instruments.
• Hospital CSSD Departments — High-throughput instrument reprocessing with frequency selected by instrument category.
• Research Facilities — Multi-protocol laboratories processing diverse equipment types.

Try more ultrasonic cleaners with various functions such as mechanical knob control, adjustable power, sweep frequency, and multiple cleaning modes.

A 30-liter ultrasonic cleaner is a significant piece of ultrasonic cleaning equipment—too large for casual use, too capable to be limited to a single cleaning mode. The K1030HTDS dental lab ultrasonic cleaner justifies its bench footprint by being the most adaptable machine in the facility. On 28kHz at high power and elevated temperature, it strips carbonized deposits from stainless steel trays and robust instruments. On 40kHz at moderate power, it processes delicate prosthetics, handpieces, and precision tools.

Besides, this kind of laboratory ultrasonic cleaner features an automatic sweep-frequency function. It can adjust the current automatically while working. The sweep frequency is not a luxury in a sonicator bath of this size; it is a necessity. Without it, the 500mm tank length would develop standing wave bands that leave some instruments barely touched by cavitation. With sweep engaged, the energy field fills the tank effectively.

FAQ

Q: How many instrument trays can this tank hold at once?

The 500x300x200mm tank typically accommodates two to three standard instrument trays, depending on their dimensions, or one large tray with clearance for cavitation circulation. For optimal cleaning, allow at least 20mm of space between trays and between trays and the tank walls. Overloading reduces cavitation effectiveness on all items in the bath.

Q: Why does a 30L tank need sweep frequency more than a smaller tank?

Standing wave formation is proportional to the ratio of tank dimension to ultrasonic wavelength. At 40kHz in a 500mm-long tank, multiple standing wave bands can form if the frequency is fixed. These create alternating zones of high and low cavitation—items in low zones receive almost no cleaning. Sweep frequency continuously shifts the operating point, preventing any single standing wave pattern from stabilizing. In a 30L tank, without sweep, you could see visible cleaning differences between the center and the ends of the tank. Sweep eliminates this problem.

Q: What power level is recommended for 28kHz operation?

For heavy-duty cleaning at 28kHz, 70–100% power is typical. The larger cavitation bubbles at 28kHz are inherently more aggressive, so even at 70% you get significant mechanical cleaning action. For delicate items inadvertently run at 28kHz, lower the power to 20–40% to moderate the impact, though switching to 40kHz is the better solution for delicate work.
