alalis AS15T Touchscreen Ultrasonic Cleaner

Overview

The alalis AS15T Touchscreen Ultrasonic Cleaner is an engineered solution for precision cleaning of delicate, high-value laboratory components—including glassware, surgical instruments, microfluidic devices, chromatography columns, optical lenses, and MEMS assemblies. It operates on the principle of cavitation: high-frequency (40 kHz) ultrasonic energy generates controlled micro-bubbles in aqueous or solvent-based cleaning media; their implosive collapse produces localized shear forces sufficient to dislodge sub-micron particulates, organic residues, biofilms, and adsorbed contaminants without mechanical abrasion or surface etching. Designed for reproducible, non-destructive cleaning across academic, clinical, pharmaceutical, and industrial QC environments, the AS15T integrates robust thermal regulation, programmable power modulation, and real-time parameter retention—ensuring compliance with GLP/GMP documentation requirements and method transfer protocols.

Key Features

• Capacitive touchscreen interface with intuitive icon-driven navigation and multilingual UI support (English, Spanish, German, French)
• 304 stainless steel tank (330 × 300 × 150 mm internal dimensions) with electropolished finish for corrosion resistance and ease of decontamination
• Adjustable ultrasonic output (40–100% of 350 W nominal power) via pulse-width modulation (PWM), enabling optimization for sensitive substrates or viscous media
• Precise temperature control (20–65 °C ± 0.5 °C) with PID-regulated heating element (380 W) and auto-compensation for ambient drift
• Programmable timer (1–199 minutes) with automatic shutdown and audible end-cycle alert
• Integrated degassing mode to remove dissolved air prior to cleaning—critical for achieving uniform cavitation intensity and eliminating shadow zones
• Leak-detection circuitry that halts operation and triggers visual/audible alarm upon detection of tank integrity compromise
• Sound-dampening lid with silicone gasket reduces operational noise to ≤55 dB(A) at 1 m distance, meeting OSHA and EU Directive 2003/10/EC workplace exposure limits
• Front-mounted drain valve and rear-fill port enable closed-loop fluid handling compatible with recirculating filtration systems
• Non-volatile memory retains up to 10 user-defined cleaning protocols—including frequency, power, temperature, time, and degas duration—even after power interruption

Sample Compatibility & Compliance

The AS15T accommodates a broad range of sample geometries and materials: hollow capillaries, porous ceramic filters, multi-well plates, semiconductor wafers, and polymer-based diagnostic cartridges. Its 15 L working volume supports batch processing of up to 48 standard 15 mL centrifuge tubes or six 100 mm Petri dishes simultaneously. All wetted surfaces comply with USP Class VI biocompatibility standards. The system adheres to ASTM D2276 (cleaning validation for fuel system components), ISO 13843 (ultrasonic cleaning performance testing), and IEC 61000-6-3 (EMC emissions). For regulated environments, optional audit-trail firmware enables 21 CFR Part 11–compliant electronic records with user authentication, timestamped event logging, and immutable protocol history.

Software & Data Management

While the AS15T operates autonomously via its embedded controller, optional USB-C data export allows CSV-formatted logs (timestamp, setpoint vs. actual temp/power, cycle status, fault codes) to be transferred for LIMS integration or QA review. Firmware updates are performed via secure signed packages delivered through alalis’ certified support portal. No cloud connectivity or remote access is implemented—ensuring full data sovereignty and alignment with institutional cybersecurity policies governing lab instrumentation.

Applications

• Pre-analytical sample preparation in clinical labs: removal of hemoglobin residue from pipette tips and cuvettes prior to spectrophotometric assays
• Cleaning of HPLC and UHPLC injection valves, frits, and guard columns to prevent backpressure drift and peak tailing
• Decontamination of reusable endoscopic tools in hospital sterilization centers per AAMI ST91 guidelines
• Removal of photoresist residuals from photomasks and wafer carriers in microfabrication cleanrooms
• Extraction support for environmental analysis: liberation of PCBs and PAHs from sediment cores using solvent-assisted sonication
• Cell culture equipment maintenance: depyrogenation of CO₂ incubator shelves and humidification trays without thermal degradation

FAQ

Is the AS15T validated for use in GMP-compliant facilities?
Yes—when equipped with audit-trail firmware and operated under documented SOPs, it satisfies FDA and EMA expectations for cleaning equipment qualification (IQ/OQ/PQ) and ongoing performance verification.
Can the unit be integrated into a centralized lab automation network?
No native Ethernet or RS-232 interface is provided; however, discrete dry-contact I/O signals (start/stop/fault) are available for PLC-level coordination.
What cleaning solutions are recommended for optimal cavitation efficiency?
Aqueous alkaline detergents (pH 9–11) or low-surface-tension solvents (e.g., isopropanol/water blends) yield highest energy transfer; avoid highly viscous or degassed media unless degas mode is activated first.
Does the system support continuous operation over multiple cycles?
Yes—thermal management and duty-cycle monitoring allow uninterrupted sequential runs, with automatic cooldown interlocks preventing sustained >65 °C tank temperatures.
How is calibration traceability maintained?
Alalis provides NIST-traceable calibration certificates for temperature and timer functions; annual verification is recommended per ISO/IEC 17025 laboratory accreditation requirements.
