4L Multifunctional Laboratory Ultrasonic Cleaner with Degas | Sweep Frequency Sonicator Bath

The K340HTDF 4L laboratory ultrasonic cleaner brings the touchscreen multifunctional experience to a 4-liter sonicator bath with 180W of ultrasonic power. The larger 300x150mm tank accommodates longer laboratory glassware while retaining the full suite of LCD-controlled features: four preset cleaning modes, degas function, automatic sweep frequency, and digital temperature control. For a teaching laboratory or quality control station, the touchscreen interface makes it easy to train new users—the cleaning mode icons and parameter readouts are self-explanatory, reducing the learning curve to near zero.

• LCD Touchscreen Interface — Intuitive mode selection and parameter adjustment on a single screen.
• 180W Ultrasonic Power — A 50% increase over the 3L model for stronger cavitation in the larger tank.
• Four Cleaning Modes — Multipurpose ultrasonic cleaner with multiple cleaning modes. Normal, Gentle, Strong, and Pulse for task-matched cleaning.
• Degas Function — Programmed degas cycle for fresh solution preparation.
• Automatic Sweep Frequency — Uniform cavitation across the 4L volume.
• 300W Heater (0–100°C) — Faster heat-up and wider temperature range than KHTD equivalents.

• Teaching Laboratories — Intuitive interface for student use with minimal supervision.
• Quality Control — Standardized cleaning with documented mode, temperature, and time.
• Research Labs — Gentle mode for sample preparation; strong mode for glassware degreasing.
• Small Instrument Processing — Dental and surgical instrument cleaning with degassing for lumens.

Anyone who has trained colleagues on lab equipment knows that the traditional button-and-knob controls of the mechanical ultrasonic cleaner are easy to use because of their simple function. But for multifunctional ultrasonic cleaners, traditional button-and-knob controls fail to perform their multifunctional features. The K340HTDF laboratory sonicator bath replaces that with a touchscreen. The home screen shows four clearly labeled cleaning modes. Tap one, and the machine configures itself for that type of cleaning. Adjust temperature and time with on-screen sliders—just like using a smartphone. No one needs to memorize button combinations or hunt through hidden menus. Every active setting is visible on one screen. In a shared laboratory, this means less time training new users and fewer mistakes on the control panel.

Q: Can I create and save my own custom cleaning program?

The K340HTDF does not have user-programmable memory slots. However, the four preset modes cover the practical range of cleaning scenarios, and you can manually adjust power within each mode. The settings you last used are retained when the machine is switched off, so your preferred configuration persists between sessions.

Q: Is this model suitable for cleaning HPLC components?

Yes. Use Gentle mode at 40–50°C for HPLC fittings, check valves, and small column components. The sweep frequency ensures uniform cavitation that reaches into the narrow internal passages of these precision parts. Always follow the component manufacturer’s cleaning recommendations regarding solvent type and ultrasonic exposure duration.
