Otisience AS3120 (Aluminum) Ultrasonic Cleaner

Overview

The Otisience AS3120 (Aluminum) Ultrasonic Cleaner is a compact, general-purpose benchtop cleaning system engineered for routine laboratory decontamination of glassware, metal parts, pipette tips, filters, and small instrumentation components. It operates on the principle of ultrasonic cavitation—where high-frequency mechanical vibrations (40 kHz) generate microscopic vacuum bubbles in the cleaning solvent that rapidly collapse, producing localized shockwaves and microstreaming effects. This physical mechanism effectively dislodges particulate matter, organic residues, biofilms, and loosely adhered contaminants without abrasive contact or chemical aggressiveness. Designed for stability and reproducibility in non-regulated or low-criticality workflows, the AS3120 delivers consistent energy transfer across its 3-liter tank volume and is widely deployed in QC labs, academic teaching facilities, and preparatory workspaces where ISO/IEC 17025 traceability is not mandated but process repeatability remains essential.

Key Features

• Stable 120 W ultrasonic power output at 40 kHz—optimized for broad-spectrum contaminant removal while minimizing sample erosion or solvent degradation
• Dual-stage power selection (50% / 100%) enables precise energy modulation for delicate versus robust substrates
• Mechanical timer with calibrated 5–30 minute range plus continuous operation mode—no electronic drift or battery dependency
• Robust anodized aluminum alloy tank and housing—corrosion-resistant, lightweight, and thermally stable under prolonged duty cycles
• Integrated noise-reduction lid—reduces airborne acoustic emission by ≥15 dB(A) during operation, improving ambient lab conditions
• Standard stainless-steel mesh basket included—facilitates uniform part suspension and prevents direct contact with transducer surface
• Manual drain/fill interface—enables controlled solvent exchange without external plumbing or pump integration

Sample Compatibility & Compliance

The AS3120 accommodates a wide range of laboratory items including volumetric flasks, cuvettes, syringe filters, HPLC vials, surgical instruments, printed circuit boards, and precision optics mounts—provided they are compatible with aqueous or mild organic solvents (e.g., isopropanol, ethanol, detergent solutions). The unit does not support heated cleaning cycles or degassing functions, and therefore is not intended for applications requiring temperature-controlled dissolution (e.g., wax or polymer residue removal) or dissolved gas elimination (e.g., prior to GC solvent injection). While not certified to UL 61010-1 or IEC 61000-6-3, its construction meets baseline electrical safety requirements for Class I laboratory equipment per GB 4793.1–2007 (Chinese national standard aligned with IEC 61010-1:2010). It is suitable for use in environments operating under GLP principles where documentation of cleaning parameters (time, power, solvent type) is maintained manually.

Software & Data Management

This model is hardware-only and features no embedded firmware, digital interface, or data logging capability. All operational parameters—including timer setting, power level selection, and cycle initiation—are managed via tactile mechanical controls. Consequently, it requires no software installation, driver configuration, or cybersecurity validation. Its simplicity ensures long-term reliability in resource-constrained or legacy infrastructure settings, and eliminates risks associated with firmware obsolescence, OS compatibility, or audit trail gaps. For laboratories subject to FDA 21 CFR Part 11 or Annex 11 requirements, manual logbook entries (including operator ID, date/time, cycle duration, and solvent batch number) constitute the sole record of cleaning activity.

Applications

• Routine cleaning of analytical glassware prior to calibration or titration
• Preparation of sampling tools for environmental or food microbiology analysis
• Removal of polishing compounds from optical lenses and metrology fixtures
• Debris clearance from microfluidic chips and MEMS devices before bonding or testing
• Supporting sample prep workflows in conjunction with ASE solid-phase extraction systems or UH-series sonicators
• Low-risk sterilization adjunct in biosafety level 1 (BSL-1) containment areas when paired with validated disinfectant solutions

FAQ

Is the AS3120 compliant with ISO 13485 or GMP standards?
No—the unit lacks documented design history files, change control procedures, and electronic audit trails required for regulated medical device or pharmaceutical manufacturing environments.
Can I use acetone or chlorinated solvents in this cleaner?
Not recommended—aluminum tank material is incompatible with strong oxidizers or halogenated hydrocarbons; only water-miscible or alcohol-based solvents should be used.
Does the unit include a heater or temperature monitoring?
No—temperature regulation is not available; solvent thermal rise is passive and limited to <5 °C above ambient over a 30-minute cycle.
What maintenance is required for long-term reliability?
Periodic inspection of the transducer mounting integrity, cleaning of the tank interior with mild detergent, and verification of lid seal compression every 6 months.
Is technical support available outside China?
Yes—Otisience provides remote troubleshooting guidance and spare parts distribution through authorized regional partners in North America, Southeast Asia, and the Middle East.
