4L Digital Heated Ultrasonic Cleaner | Lab Benchtop Sonicator for Glassware & Instruments

The K340HTD 4L digital heated ultrasonic cleaner is a purpose-built laboratory benchtop sonicator for cleaning glassware and instruments. Its 4-liter sonicator bath with 180W of ultrasonic power handles a batch of beakers, a set of pipettes, or multiple small instrument trays in a single cycle. The 300x150mm rectangular tank footprint accommodates longer items—graduated cylinders, glass rods, and chromatography accessories—that would not fit in the smaller 3L model. The digital interface provides the precision and repeatability that laboratory protocols demand.

• 180W Ultrasonic Power – Lab benchtop sonicator with strong cavitation for removing stubborn residues from laboratory glassware.
• 300W Heater – Reaches set temperature rapidly; digital control thermostat makes cleaning effective.
• 4L Rectangular Tank – 300mm length accommodates elongated lab items.
• Digital Controls with Degas – Set temperature and time precisely; degas fresh solution before each protocol.
• Stainless Steel Tank & Housing – Resists corrosion from common lab detergents and mild acids.

• Laboratory Glassware – Lab benchtop sonicator for cleaning beakers, flasks, test tubes, graduated cylinders, and petri dishes.
• Lab Instruments – Laboratory ultrasonic cleaner for cleaning forceps, spatulas, stir bars, and small stainless steel tools.
• Sample Preparation – Digital ultrasonic cleaner for degassing HPLC solvents and accelerating dissolution of solid samples.
• Small Instrument Trays – Ultrasonic instrument cleaner for dental and surgical instrument cassettes in clinical settings.

In a busy laboratory, this 4-liter digital ultrasonic cleaner earns its bench space by handling the constant flow of soiled glassware. Rather than scrubbing beakers by hand—which risks breakage and exposes staff to residues—the technician loads the basket, sets the digital timer and temperature, and returns to other tasks. The degas function is run once after filling, and subsequent cycles that day can be started immediately with full cavitation efficiency.

Q: Can I use a mild acid solution in this tank for descaling glassware?

Yes, the 304 stainless steel ultrasonic cleaning tank is resistant to mild acids such as dilute citric acid or acetic acid solutions commonly used for descaling. Avoid strong acids, chlorides, and bleach-based solutions, which can pit stainless steel over extended contact.

Q: What kind of glassware should NOT be cleaned ultrasonically?

Avoid ultrasonically cleaning volumetric glassware that requires calibration, as prolonged cavitation could theoretically affect precision markings. Fritted glass filters and thin-walled capillary tubes should also be evaluated for compatibility. For most standard borosilicate laboratory glassware, ultrasonic cleaning at 40kHz is safe and effective.
