15L Medical Ultrasonic Cleaner for Dental Instruments | 28/40kHz Dual Frequency Sonicator Bath

This is the K615HTDS 15-liter medical ultrasonic cleaner for cleaning laboratory and dental instruments. It is a dual-frequency ultrasonic cleaner, combining 360W of adjustable ultrasonic power, a 600W heater, and genuine 28/40kHz switching in a tank sized for clinical instrument throughput. For medical and dental facilities that reprocess reusable instruments, this dual-frequency ultrasonic instrument cleaner addresses a real operational need: 28kHz for the heavy soil load of general surgical instruments, and 40kHz for delicate ophthalmic tools, dental handpieces, and fine-tipped instruments that could be damaged by aggressive low-frequency cavitation. One machine, two distinct cleaning modes, validated by the digital parameter display.

• True 28/40kHz Dual Frequency — Selectable frequency with genuine cavitation characteristics at both settings; not a marketing term, an engineering reality.
• 360W Ultrasonic Power (5–100% Adjustable) — Strong cavitation density across the 15L volume; adjustable independent of frequency.
• 600W Heater (0–100°C) — High-capacity heating for rapid temperature rise and stable maintenance during long processing runs.
• Automatic Sweep Frequency — Uniform cavitation at both 28kHz and 40kHz; particularly important at 28kHz, where standing waves can be more pronounced.
• 15L Cleaning Bath (330x300x150mm) — Fits standard instrument trays, multiple cassettes, and bulk loads of smaller instruments.

• 28kHz – General Surgical Instruments — General ultrasonic instrument cleaner for forceps, hemostats, needle holders, retractors, and rigid stainless steel tools.
• 40kHz – Delicate & Precision Instruments — Precision ultrasonic instrument cleaner for ophthalmic instruments, microsurgical tools, dental handpieces, and instruments with fine hinges or coatings.
• Dental Clinics — Instrument cassettes, bur blocks, and prosthetic components with frequency selected according to material and condition.
• Veterinary Practices — Mixed instrument loads where both heavy and delicate tools are processed.

Not all surgical instruments tolerate the same cleaning intensity. Stainless steel forceps, retractors, and rigid scopes can withstand—and benefit from—the aggressive 28kHz cavitation that strips bioburden from hinges and serrations. Delicate ophthalmic instruments, microsurgical tools, and dental handpieces with precision bearings are better served by 40kHz, where the smaller cavitation bubbles clean effectively without mechanical stress on fine structures. The K615HTDS gives instrument processing staff a clear choice, with documented parameters for each instrument category.

Q: Which frequency should I use for dental handpieces?

40kHz is recommended for dental handpieces. The smaller cavitation bubbles at this frequency clean effectively around the turbine and bearing areas without the mechanical stress that 28kHz could impart on precision components. Always follow the handpiece manufacturer’s ultrasonic cleaning compatibility statement. Some handpiece manufacturers specify a maximum frequency and power level.

Q: Can I run a mixed load of robust and delicate instruments?

It is not recommended to process mixed loads requiring different frequencies. The instruments that need 40kHz protection would be exposed to 28kHz energy if run together. Instead, batch instruments by frequency requirement: run the 28kHz cycle for robust instruments, then switch to 40kHz for delicate ones. The frequency change takes seconds, and the tank does not need to cool down between cycles.

Q: Is there a difference in noise level between the two frequencies?

Yes. 28kHz operation produces a deeper, more audible hum because the cavitation implosions are physically larger and more energetic. 40kHz operation is quieter and higher-pitched. Both are normal and indicate the machine is producing genuine cavitation at the selected frequency.
