Ultrasonic Cleaning Objects

• Lab glassware: beakers, flasks, test tubes, pipettes, microscope slides (laboratory equipment often cleaned of chemical residues).
• Electronic components: printed circuit boards (PCBs), microchips, soldered assemblies (requires gentle cleaning to remove flux and debris).
• Automotive parts: engine blocks, carburetors, fuel injectors, valves (heavy grease and carbon deposits removed from metal components).
• Medical & dental instruments: surgical tools, dental handpieces, forceps, endoscope parts (cleaning removes blood, tissue, and contaminants before sterilization).
• Jewelry & watch components: rings, necklaces, bracelets, watch movements, gears (precious metal pieces cleaned of tarnish, oils, and dirt).
• Optical items: camera lenses, eyeglasses, microscope optics, glass filters (delicate surfaces cleaned of fingerprints and dust).
• Industrial hardware: molds, nozzles, bearings, firearm parts (machined metal parts with intricate crevices or carbon residue benefit from ultrasonic cleaning).

Ultrasonic Removing Contaminant

• Oil and grease: machine oil, lubricants, heavy grease deposits (common soils from engines and machinery).
• Dust and dirt: particulate matter, soil, general grime (accumulates on equipment surfaces).
• Fingerprints and oils: skin oils, smudges, light films (often found on lenses and precision parts).
• Polishing compounds: buffing rouge, lapping paste, polishing wax (residues from finishing processes).
• Rust and oxidation: corrosion, tarnish, oxide layers (metal parts with rust or oxidized film).
• Carbon residues: soot, burnt carbon deposits (from combustion engines or firing residues).
• Blood and biological stains: dried blood, tissue residue, biofilms (on medical and dental instruments).
• Flux and solder residue: solder paste, flux char, ionic residues (left on PCBs after soldering).

Recommended Frequency by Object/Contaminant (Frequency Guidance)

• 25–28 kHz (Low frequency): Strong cavitation for heavy-duty cleaning of robust metal parts with tenacious contaminants (e.g. engine blocks, injection molds).
• 40 kHz (Standard frequency): General-purpose cleaning for a wide range of materials and common contamination (the most widely used ultrasonic frequency for labware, tools, and general metal parts).
• 68–80 kHz (Higher frequency): Finer cleaning for delicate or complex items – smaller cavitation bubbles penetrate intricate crevices and blind holes (ideal for precision optics, small jewelry, and parts with complex geometry).
• 120 kHz (Ultrasonic/Megasonic): Ultra-fine cleaning for highly sensitive components – gentle cavitation used in microelectronics and precision optics to remove microscopic particles and dust without damage.
• Dual-frequency systems: e.g. 40/80 kHz switchable – offer versatility to handle both coarse and fine cleaning needs in one machine.

Note: High-frequency megasonic cleaners (>120 kHz) are often used for semiconductor wafers and final rinsing of ultra-delicate parts.

Ultrasonic Cleaner Application Industry

• Research laboratory: University and industrial labs cleaning glassware and experiment apparatus (fast removal of residues from beakers, test tubes, etc. for next use).
• Dental clinic: Cleaning of dental tools, drills, and molds – ensures instruments (burs, scalers, mirrors) are free of blood and debris before sterilization.
• Medical facility (Hospital CSSD): Pre-sterilization cleaning of surgical instruments and endoscopic equipment – thorough removal of bioburden to meet medical hygiene standards.
• Semiconductor fabrication: Cleanroom use for silicon wafers, masks, and precision parts – megasonic cleaners remove microscopic particles in chip manufacturing lines.
• Watchmaker & jewelry workshop: Precision cleaning of watch movements, clock parts, and jewelry pieces – restores shine and removes polishing compounds from intricate items.
• Aerospace maintenance: Overhaul shops for aerospace/aviation parts – ultrasonic baths clean turbine components, fuel system parts, and hydraulic valves of oils, carbon, and contaminants.
• Automotive repair garage: Service centers using ultrasonic parts washers for carburetors, fuel injectors, and engine components – quick removal of grease, varnish, and carbon buildup to improve performance

Technical Description

• Industrial ultrasonic bath: large-capacity or heavy-duty cleaner for industrial use (suitable for manufacturing or automotive applications).
• Reliable precision cleaning system: High-performance cleaning for intricate or sensitive parts.
• OEM/ODM China supplier: Original equipment manufacturer in China offering customizable ultrasonic cleaners.
• Stainless steel SUS304 tank: Emphasizes durable 304-grade stainless steel construction of the cleaning tank.
• Noise Reduction:
  – Double-layer sound insulation structure (sound-damping foam + precision circuits)
  – Operates <80dB for 68kHz+, ideal for quiet lab environments
• Degas function: Feature that removes dissolved air from the cleaning solution for improved cavitation efficiency (prevents air bubbles from hindering cleaning).
• Sweep frequency technology: Feature that continuously modulates the ultrasonic frequency to eliminate standing waves and ensure uniform cleaning, avoiding damage from resonance.
• Pulse mode: High-power burst setting that delivers intensified cavitation for short periods to dislodge especially stubborn contaminants.
• Digital timer & temperature control: Indicates the cleaner has a programmable timer and heating element with digital controls for precise operation (e.g. adjustable cleaning time, thermostat settings).
• Multiple-frequency option: Some systems offer switchable or dual frequencies (e.g. 28 kHz & 68 kHz in one unit) to adapt to different cleaning tasks, a selling point for versatile usage.
• CE/FCC certified equipment: Compliance with safety and quality standards.
