22L Ultrasonic Cleaning Bath for Lab Equipment & Instruments | Adjustable Power Ultrasonic Cleaner

This is the K820HTDP 22L ultrasonic cleaning bath for cleaning lab equipment and instruments. It brings 22 liters of variable power ultrasonic cleaning to the laboratory and clinical environment. With 480W of adjustable output, an 800W heater, and a 500x300mm elongated tank, it handles instrument trays, large glassware, and small equipment components that exceed the capacity of 15L machines. The adjustable power and sweep frequency combination means this ultrasonic bath cleaner can process delicate instruments requiring low power alongside heavily soiled items needing maximum intensity—all with the uniformity that only sweep technology provides.

• 480W Ultrasonic Power (5–100% Adjustable) — The highest wattage in the benchtop adjustable power series ultrasonic bath for strong cavitation across a large volume.
• Automatic Sweep Frequency — Uniform energy distribution across the full 500x300mm footprint makes it a wonderful lab equipment ultrasonic cleaner.
• 800W Heater (0–100°C) — Industrial-grade heating for large-volume temperature control.
• 22L Ultrasonic Cleaning Bath (500x300x150mm) — Long rectangular shape accommodates instrument trays, chromatography equipment, and elongated lab items.
• Drain Tap — Standard on this model for practical solution management in a tank too large to tip.
• Digital Controls with Continuous Run Mode — Precise timer and temperature control plus extended-run capability.

• Clinical Instrument Processing — Surgical trays, instrument cassettes, and multiple handpieces in one load.
• Laboratory Equipment — Chromatography accessories, fraction collectors, and large glassware assemblies.
• Dental Lab Work — Denture frameworks, model holders, and large prosthetic components.
• Research Equipment — Components that require documented cleaning with adjustable intensity.

Laboratory equipment often does not fit in standard benchtop ultrasonic cleaning baths. A fraction collector assembly, a set of chromatography columns, or a tray of surgical instruments demands the length that only a 500mm tank can provide. The K820HTDP meets this need while retaining the adjustable power advantage—run instrument trays at 70% power and 60°C for effective bioburden removal, then switch to 20% power for rinsing delicate components. The sweep function ensures the elongated ultrasonic bath does not develop energy gradients along its length.

Ultrasonic cleaning is an effective way for laboratory instruments. But, how to make the cleaning work of ultrasonic lab equipment cleaner effectively? There are some points we should remember.

First, make sure to put the glassware in the cleaning basket. Choose a cleaning basket that fits the water bath, so that the items do not touch the bottom of the sonicator bath.

Second, use proper ultrasonic cleaning solutions for lab glassware. Improper detergents may cause some damage to the glassware. So pay attention to the specific cleaning chemicals before cleaning.

FAQ

Q: Can I clean multiple instrument trays simultaneously?

Yes, depending on tray dimensions. The 500x300mm footprint accommodates two standard small instrument trays side by side, or one large tray with clearance for cavitation circulation. Avoid stacking trays or packing them tightly, as cavitation requires liquid to flow around each instrument.

Q: Is the drain tap included as standard?

Yes. At 22 liters, the tank weighs over 22 kg when full, which is impractical and unsafe to tip for emptying. The front-mounted drain tap allows gravity drainage into a bucket or floor drain in 3–5 minutes.
