AS ONE AS12GTU Ultrasonic Cleaner (220 V AC)

Overview

The AS ONE AS12GTU Ultrasonic Cleaner is a compact, general-purpose benchtop ultrasonic cleaning system engineered for precision and reliability in routine laboratory environments. It operates on the principle of high-frequency ultrasonic cavitation—typically at 40 kHz—to generate microscopic implosions in liquid media, effectively dislodging particulate contaminants, organic residues, and loosely adhered films from delicate instrumentation, glassware, metal components, and small-scale sample holders. Designed for consistent performance across diverse aqueous and mild solvent-based cleaning protocols, the AS12GTU delivers reproducible cleaning efficacy without mechanical abrasion or thermal stress. Its robust stainless-steel construction ensures long-term corrosion resistance and compatibility with standard laboratory cleaning agents—including alkaline, neutral, and low-concentration acidic solutions—while maintaining structural integrity under repeated thermal and acoustic loading.

Key Features

• Stainless-steel tank and basket fabricated from SUS304 grade material, offering superior resistance to pitting, oxidation, and chemical degradation in common lab cleaning formulations.
• Integrated drain valve for controlled, spill-free solution disposal—enhancing workflow efficiency and reducing operator exposure during maintenance cycles.
• Compact footprint (160 × 180 × 220 mm) optimized for space-constrained fume hoods, analytical workstations, and QC/QA laboratories.
• Uniform ultrasonic energy distribution across the 2 L tank volume (internal dimensions: 140 × 150 × 100 mm), minimizing standing wave interference and ensuring consistent cleaning across submerged samples.
• Stable 220 V AC input operation compliant with standard industrial power infrastructure across Asia, Europe, and Latin America—no external voltage conversion required.
• Thermally insulated housing with passive cooling design to maintain safe surface temperatures during extended operation (up to 30 min continuous duty cycle).

Sample Compatibility & Compliance

The AS12GTU accommodates a broad range of sample geometries and materials, including but not limited to: borosilicate glass vials, quartz cuvettes, stainless-steel forceps and tweezers, ceramic crucibles, aluminum sample holders, and polymer-based microcentrifuge tubes (when used with compatible solvents). It is not recommended for use with highly volatile solvents (e.g., acetone, ether) unless operated within certified explosion-proof enclosures. The unit meets general electrical safety requirements per IEC 61010-1 for laboratory equipment and conforms to RoHS Directive 2011/65/EU for hazardous substance restrictions. While not certified for medical device reprocessing under ISO 15883 or EN 285, it supports GLP-aligned cleaning validation when integrated into documented SOPs for non-sterile preparatory workflows.

Software & Data Management

The AS12GTU is a manually operated analog unit with no embedded microprocessor, touchscreen interface, or digital data logging capability. Timer functionality is implemented via a mechanical rotary dial (0–30 min range), enabling repeatable exposure duration control without software dependency. This architecture eliminates firmware-related cybersecurity risks, simplifies regulatory documentation for audit trails, and ensures operational continuity in environments where IT infrastructure limitations or electromagnetic interference may compromise digital controllers. For laboratories requiring electronic recordkeeping, integration with external time-stamped environmental monitoring systems (e.g., temperature/humidity loggers) is supported via standard USB or RS-232 interfaces on companion data acquisition hardware.

Applications

• Pretreatment of HPLC vials, GC autosampler inserts, and ICP-MS sample cones prior to trace-metal analysis.
• Cleaning of optical components—including microscope slides, lens mounts, and spectrometer mirrors—without surface scratching.
• Removal of solder flux residues from PCB test fixtures and microelectronics assembly jigs.
• Decontamination of reusable pipette tips, filtration housings, and centrifuge rotor adapters between runs.
• Supporting ASTM D2621 and ISO 10545-14 protocols for ceramic and tile surface cleanliness verification in materials testing labs.
• Preparatory cleaning of electrodes, reference cells, and electrochemical flow cells prior to calibration or electrochemical impedance spectroscopy (EIS) measurements.

FAQ

What is the maximum operating temperature of the cleaning solution?
The AS12GTU does not include active heating; solution temperature rise is limited to ambient +5 °C under typical 40 kHz operation. External water baths or heated tanks must be used for elevated-temperature cleaning protocols.
Is this unit suitable for cleaning delicate MEMS devices?
Yes—provided appropriate frequency selection (if adjustable on future variants) and low-power settings are employed. For current AS12GTU, use deionized water or low-surface-tension surfactant solutions at reduced duty cycles (e.g., 5 min on / 5 min off) to mitigate potential micro-cavitation erosion.
Does the unit comply with FDA 21 CFR Part 11 for electronic records?
No—this is an analog-only instrument with no electronic data generation or user authentication capabilities. It may be used in Part 11-regulated environments only when cleaning parameters are manually recorded in bound lab notebooks or validated paper-based logs.
Can the drain valve be retrofitted to older AS GTU-series models?
No—the drain valve is integrated into the tank casting and cannot be field-installed on units lacking the pre-machined port and sealing interface.
What maintenance intervals are recommended for optimal transducer longevity?
Inspect tank integrity and transducer mounting bolts quarterly; clean tank interior with non-abrasive citric acid solution biannually to prevent mineral scale accumulation on ultrasonic transducers.
