What Is an Ultrasonic Cleaner?
An ultrasonic cleaner uses high-frequency sound waves (typically 40 kHz) to create microscopic cavitation bubbles in a cleaning solution. These bubbles implode near surfaces, dislodging contaminants such as dust, grease, oil, flux, protein residues, and biological debris. Hawach ultrasonic cleaners feature digital controls, adjustable heating, programmable timer, degassing mode, and 304 stainless steel tanks.
How Ultrasonic Cleaning Works – The Science Behind Cavitation
- Mechanical scrubbing– Cavitation removes particles without abrasion, reaching crevices that brushes cannot access.
- Degassing mode– Removes dissolved air before operation, improving cavitation efficiency and reducing noise.
- Heating– Warmer solutions (up to 80°C) accelerate chemical reactions and soften residues.
Ultrasonic Cleaner Frequency – 28kHz vs 40kHz vs 80kHz
| Frequency | Cavitation Intensity | Best For | Typical Applications |
| 28 kHz | High intensity | Heavy contamination, robust surfaces | Metal parts, automotive components, castings, heavy grease/oil removal |
| 40 kHz (Hawach standard) | Medium intensity | General laboratory cleaning, most glassware, instruments | Laboratory beakers, HPLC vials, surgical tools, circuit boards |
| 80 kHz | Low intensity | Delicate surfaces, soft materials | Optics, silicon wafers, membranes, fine filters, microelectronics |
Hawach ultrasonic cleaners are 40 kHz as standard. Dual-frequency or 28/80 kHz options available on request.
Recommended Ultrasonic Cleaning Times
| Cleaning Task | Recommended Time | Notes |
| Light cleaning (dust, fresh residues) | 3-5 min | Low power density |
| HPLC mobile phase degassing | 10-15 min | Use degassing mode |
| Routine laboratory glassware | 10-20 min | With heating (40-50°C) |
| Protein residue removal (surgical instruments) | 15-25 min | With enzymatic cleaner, heating 50-60°C |
| Heavy grease, oil, carbon deposits | 20-30 min | Use stronger cleaning solution |
| Stubborn contaminants (dried-on, baked-on) | 30-45 min | May require multiple cycles |
Ultrasonic Cleaner vs Sonicator – What‘s the Difference?
Sonicator is often used as a synonym for ultrasonic cleaner, especially in research settings. Technically, a sonicator typically refers to a probe-type ultrasonic device (cell disruptor) used for lysing cells or dispersing nanoparticles. An ultrasonic cleaner (bath-type) is designed for cleaning, degassing, and gentle mixing. Hawach ultrasonic cleaners are bath-type units optimized for laboratory cleaning and HPLC degassing.
Ultrasonic Cleaner vs Manual Cleaning – Which Is Better?
| Factor | Ultrasonic Cleaner | Manual Scrubbing |
| Time per batch (glassware) | 10-20 min (unattended) | 30-60 min (hands-on) |
| Reach into complex parts | Excellent (cavitation) | Poor (brushes cannot reach) |
| Risk of glassware breakage | Very low | Moderate |
| Reproducibility | High (digital timer) | Low (operator-dependent) |
| Labor cost | Minimal | High |
For most laboratory applications, ultrasonic cleaning significantly reduces time and labor while improving consistency. Manual scrubbing may still be needed for heavy caked residues before ultrasonic processing.
Ultrasonic Cleaner Power – How Much Wattage Do You Need?
| Capacity | Ultrasonic Power | Power Density (W/L) | Cleaning Intensity |
| 2L | 60W | 30 W/L | High – good for tough residues |
| 3L | 120W | 40 W/L | Very high – ideal for heavy contamination |
| 6L | 180W | 30 W/L | High – balances power and capacity |
| 10L | 240W | 24 W/L | Medium-high – routine lab cleaning |
| 15L | 360W | 24 W/L | Medium-high – pharmaceutical equipment |
| 22L | 480W | 22 W/L | Medium – industrial parts |
| 30L | 600W | 20 W/L | Medium – bulk cleaning |
Ultrasonic Cleaner for HPLC Mobile Phase Degassing
Degassing of HPLC mobile phases is a standard application. Ultrasonic degassing removes dissolved gases, reducing baseline noise and improving retention time stability. Recommended models: 2L or 3L with degassing mode.
Applications of Ultrasonic Cleaners in Laboratory & Industry
Laboratory glassware cleaning – Removes protein residues, dried salts, organic compounds.
Surgical instruments & medical devices – Effective removal of blood, tissue, and biofilms.
Electronic parts & circuit boards – Removes flux, solder paste, dust, ionic contaminants.
Industrial parts & metal components – Degreasing of machined parts, removal of cutting oils.
How to Choose the Right Ultrasonic Cleaner Capacity
- 2L-3L: HPLC vials, small beakers, dental instruments
- 6L-10L: Routine glassware cleaning, multiple beakers, surgical instruments
- 15L-22L: High-throughput pharmaceutical QC, production lines
- 30L: Industrial parts, bulk cleaning, large components
