4L Variable Power Ultrasonic Bath Sonicator for Dental & Lab Cleaning | Sweep Frequency

The K340HTDP 4L variable-power ultrasonic bath sonicator extends the adjustable power concept to a 4-liter platform with 180W of maximum ultrasonic output. It is an advanced sweep-frequency ultrasonic cleaner for dental instrument cleaning and lab soncating. The larger 300x150mm ultrasonic bath accommodates longer glassware—graduated cylinders, pipettes, and chromatography accessories—while retaining the full 5–100% power range and automatic sweep frequency of the KHTDP series adjustable power ultrasonic cleaner. For laboratories that need precision control in a medium benchtop format, this model bridges the gap between compact and mid-sized variable power machines.

• 180W Ultrasonic Power (5–100% Adjustable) — Variable power ultrasonic bath providing stronger cavitation at the top end while retaining the ability to go very gentle at low settings.
• Automatic Sweep Frequency — Sweep frequency ultrasonic cleaning eliminates dead zones for uniform cleaning across the 4L tank.
• 4L Ultrasonic Bath (300x150x100mm) — Rectangular shape ultrasonic bath sonicator suited to longer lab items.
• 300W Heater (0–100°C) — Wider temperature range and faster heat-up than the 3L model.
• Digital Timer & LED Display — Precise control with clear readout.

• Optical Components — Low-power cleaning of lenses, mirrors, and coated optics where surface damage must be avoided.
• Chromatography Accessories — HPLC fittings, columns, and sample vials cleaned at moderate power.
• Laboratory Glassware — Laboratory ultrasonic bath provides routine and deep cleaning of beakers, flasks, and graduated cylinders.
• Precision Mechanical Parts — Ultrasonic parts cleaner for cleaning small bearings, gears, and instrument components.

The jump from 120W to 180W means that at any given percentage setting, the K340HTDP ultrasonic bath sonicator delivers proportionally more cavitation energy than the 3L model. At 50% power, you get 90W of effective output—enough for routine cleaning with reserve capacity. At 100%, the full 180W tackles residues that a smaller machine might leave behind, while the sweep function ensures this energy is distributed evenly, not concentrated in hot spots.

FAQ

Q: Can I clean optical lenses at low power without damaging coatings?

Yes. At 5–15% power, the cavitation is gentle enough for most coated optical surfaces when using an appropriate cleaning solution and a short cycle time. Always verify compatibility with the lens manufacturer. Use a suspended holder to keep lenses from contacting the tank bottom, where cavitation is strongest.

Q: What is the difference between the 0–80°C range on the KHTD series and the 0–100°C range here?

The KHTDP series variable power sonicators heater and thermostat are specified for a 100°C maximum, which can be useful for applications requiring near-boiling temperatures, such as certain extraction protocols or accelerated cleaning of heavy polymerized residues. In practice, water-based solutions will boil at approximately 100°C; use appropriate caution at the top of the temperature range.
