Otisience AS3120A Ultrasonic Cleaner

Overview

The Otisience AS3120A Ultrasonic Cleaner is a compact, general-purpose laboratory-grade cleaning system engineered for precision and reliability in routine sample preparation workflows. It operates on the principle of ultrasonic cavitation—generating high-frequency acoustic energy at 40 kHz to induce controlled microbubble formation and collapse within aqueous or compatible solvent media. This physical mechanism delivers effective removal of particulate contaminants, organic residues, and loosely adhered biofilms from delicate instrumentation components (e.g., pipette tips, HPLC vials, glassware, surgical tools, and semiconductor wafers) without mechanical abrasion or thermal degradation. Designed for consistent performance across diverse lab environments—from QC/QA laboratories to academic research facilities—the AS3120A integrates robust transducer coupling, stable power delivery, and user-configurable intensity settings to support reproducible cleaning outcomes aligned with standard operating procedures.

Key Features

• 120 W ultrasonic power output with continuously adjustable intensity (30–100%), enabling optimization for sensitive substrates or heavily soiled samples.
• Dual-timer architecture: electronic timer (0–20 min) for precise cycle control and mechanical timer (0–30 min) for simplified operation; both support continuous mode for extended cleaning protocols.
• Integrated degassing function facilitates rapid removal of dissolved air prior to cleaning, enhancing cavitation efficiency and reducing process variability.
• Sound-dampening lid minimizes ambient noise emission during operation—critical for shared laboratory spaces where acoustic compliance is required.
• Corrosion-resistant construction: 304 stainless steel tank ensures long-term chemical compatibility with common cleaning solvents (e.g., isopropanol, acetone, aqueous alkaline solutions); aluminum housing features electrophoretic coating for durability in humid environments.
• Compact footprint (265 × 160 × 240 mm) and 3 L capacity provide optimal balance between benchtop usability and throughput for small-batch applications.

Sample Compatibility & Compliance

The AS3120A accommodates a wide range of laboratory consumables and instruments—including volumetric flasks, cuvettes, filtration membranes, microcentrifuge tubes, and reusable chromatography columns—without risk of surface pitting or dimensional distortion when operated within recommended parameters. Its 40 kHz frequency is optimized for medium-to-fine particle removal (typically <50 µm), making it suitable for pre-analytical cleaning prior to spectroscopic, chromatographic, or elemental analysis. While not certified for medical device reprocessing under ISO 15883 or FDA 510(k), the unit meets general electrical safety requirements per IEC 61010-1 and supports GLP-aligned documentation practices through manual log entry of operational parameters (time, power setting, solvent type). For regulated environments requiring audit trails, integration with external environmental monitoring systems is supported via analog timer outputs.

Software & Data Management

The AS3120A is a standalone hardware platform with no embedded firmware or digital connectivity. All operational parameters—including timer selection, power level, and degassing activation—are managed via front-panel mechanical switches and rotary dials. This analog interface eliminates cybersecurity vulnerabilities and ensures uninterrupted functionality in labs with restricted network access or electromagnetic interference concerns. Users maintain full traceability by recording settings manually in laboratory notebooks or electronic lab notebooks (ELNs), aligning with 21 CFR Part 11 principles when paired with validated documentation workflows. No proprietary software, drivers, or cloud services are required or supported.

Applications

• Preparation of analytical glassware prior to UV-Vis, AAS, or ICP-MS analysis to eliminate trace metal carryover.
• Cleaning of reusable HPLC/GC autosampler vials and injection syringes to prevent cross-contamination between runs.
• Removal of residual solder flux or photoresist from PCBs and microelectromechanical systems (MEMS) during R&D prototyping.
• Decontamination of reusable cell culture inserts and transwell membranes prior to reuse in barrier integrity assays.
• Routine maintenance of optical components (e.g., microscope slides, prism mounts) where solvent immersion must avoid scratching or coating damage.
• Supporting ASTM D2621 (standard test method for ultrasonic cleaning of automotive parts) and ISO 13485-aligned cleaning validation protocols for Class I/IIa medical device manufacturing.

FAQ

Is the AS3120A compliant with FDA or ISO standards for medical device cleaning?
No—this model is intended for general laboratory use and does not carry regulatory certification for sterile reprocessing. Validation for clinical applications requires supplementary testing per ISO 15883-1 and user-defined protocol qualification.
Can the unit be used with flammable solvents such as acetone or ethanol?
Yes, but only in well-ventilated fume hoods with appropriate explosion-proof infrastructure. The AS3120A lacks intrinsic safety certification (ATEX/IECEx) and must not be operated in uncontrolled solvent vapor environments.
Does the timer retain settings after power interruption?
No—the mechanical and electronic timers reset upon power loss. Continuous operation mode remains available without timing constraints.
What is the expected service life of the ultrasonic transducers?
Under normal usage (≤4 hours/day, proper solvent maintenance), transducers typically deliver >5,000 hours of functional operation before measurable output decay occurs.
Is technical support available outside China?
Yes—Otisience provides remote diagnostics and application guidance globally through authorized distributors and its Montreal-based engineering support team. Field service is coordinated regionally via partner networks.
