alalis AS03T Touchscreen Ultrasonic Cleaner

Overview

The alalis AS03T Touchscreen Ultrasonic Cleaner is a precision-engineered benchtop ultrasonic cleaning system designed for laboratories requiring consistent, non-destructive removal of particulate contaminants, organic residues, and loosely adhered films from delicate and geometrically complex samples. Operating on the principle of cavitation—generated by high-frequency (40 kHz) acoustic energy transmitted through aqueous or mild solvent-based cleaning media—the AS03T produces controlled microbubble implosion at surfaces, enabling effective cleaning of blind holes, microchannels, threaded components, and microfluidic devices without mechanical abrasion or surface erosion. Its compact 3-liter tank volume and regulated thermal and temporal parameters make it especially suitable for routine QC/QA workflows in analytical chemistry, biomedical device reprocessing, semiconductor component preparation, and academic research labs where space efficiency and reproducibility are critical.

Key Features

• Intuitive 4.3-inch capacitive touchscreen interface with icon-driven navigation and multilingual support (English, Spanish, French), enabling rapid parameter setup and real-time status monitoring.
• Digitally adjustable ultrasonic power output (40–100% in 10% increments), optimized via pulse-width modulation (PWM) to maintain stable cavitation intensity across varying load conditions and liquid levels.
• Independent temperature control (20–65 °C, ±1 °C accuracy) with integrated PTC heating element (90 W) and PID feedback loop, supporting enzymatic, low-temperature, and accelerated cleaning protocols.
• Precision programmable timer (1–199 minutes) with auto-shutdown and audible end-of-cycle alert; all active settings—including power level, temperature setpoint, and duration—are retained after power interruption via non-volatile memory.
• Robust 304 stainless steel tank with electropolished interior finish and corrosion-resistant powder-coated steel housing, compliant with ISO 14644-1 Class 7 cleanroom-compatible surface requirements.
• Dual-layer sound-dampening lid with silicone gasket seal reduces ambient noise to ≤55 dB(A) at 1 m distance and minimizes solvent evaporation during extended operation.
• Integrated leak detection circuitry monitors tank integrity continuously; automatic shutdown occurs within 200 ms upon detecting abnormal current draw or ground fault, meeting UL 61010-1 and IEC 61000-6-3 safety standards.
• Anti-slip, height-adjustable rubber feet ensure stability on uneven workbenches; optional accessories include mesh baskets, beaker holders, and degassing trays for specialized sample configurations.

Sample Compatibility & Compliance

The AS03T accommodates a broad range of sample types including glassware (vials, cuvettes, pipette tips), metal parts (surgical instruments, calibration standards), ceramic substrates, polymer microplates, and silicon wafers. It is validated for use with deionized water, alkaline detergents (e.g., Alconox®), ethanol/water mixtures, and low-concentration surfactant solutions. The unit complies with key international regulatory frameworks relevant to laboratory instrumentation: FDA 21 CFR Part 11-ready firmware architecture (audit trail logging available via optional USB export), GLP/GMP-aligned operational traceability, and electromagnetic compatibility per EN 61326-1. While not certified for sterile processing per ISO 17664 or AAMI ST79, it supports pre-sterilization cleaning steps aligned with USP and ASTM D2603-20 guidelines for ultrasonic cleaning validation.

Software & Data Management

The AS03T operates autonomously without external PC dependency. All operational data—including cycle start/stop timestamps, actual vs. set temperature/power profiles, and fault logs—are stored internally for up to 1,000 cycles. Optional USB-C data export enables CSV-formatted reporting compatible with LIMS integration (e.g., LabVantage, Thermo Fisher SampleManager). Firmware updates are performed via secure signed .bin files; version history and calibration verification records adhere to ISO/IEC 17025 documentation requirements for accredited testing laboratories.

Applications

• Routine cleaning of HPLC autosampler vials, GC inlet liners, and ICP-MS nebulizers prior to trace-metal analysis.
• Preparation of TEM grid specimens and AFM cantilevers to eliminate hydrocarbon contamination.
• Removal of solder flux residues from PCB prototypes and MEMS packaging substrates.
• Decontamination of reusable biosafety cabinet tools and centrifuge rotors in BSL-2 environments.
• Supporting ASTM E1753-22 standard practice for evaluating cleaning efficacy of medical device components.
• Academic teaching labs: hands-on instruction in sonochemistry fundamentals, cavitation threshold measurement, and cleaning process optimization.

FAQ

Is the AS03T suitable for cleaning delicate optical lenses or coated surfaces?
Yes—when operated at reduced power (40–60%) and low temperatures (20–35 °C) using non-ionic, low-foaming detergents, the AS03T has been verified to clean anti-reflective coated optics without measurable coating degradation (per MIL-C-48497A adhesion testing).
Does the unit support continuous operation mode?
No—maximum single-cycle duration is 199 minutes; however, sequential cycles can be queued manually. For unattended overnight cleaning, users must configure repeated manual starts.
Can the heating function operate independently of ultrasonic activation?
Yes—“Heat Only” mode allows temperature equilibration without cavitation, useful for degassing solvents or pre-warming cleaning baths.
What maintenance is required to sustain performance over time?
Monthly inspection of transducer coupling integrity, quarterly descaling of the tank interior using 5% citric acid solution, and annual verification of temperature sensor calibration against NIST-traceable reference thermometers.
Is the AS03T CE-marked for use in the European Union?
Yes—the device carries full CE marking under the Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU, with technical documentation available upon request from alalis authorized distributors.
