Alalis AS15 Touchscreen Ultrasonic Cleaner

Overview

The Alalis AS15 Touchscreen Ultrasonic Cleaner is a precision-engineered, general-purpose ultrasonic cleaning system designed for laboratories requiring consistent, non-destructive removal of particulate, organic, and oily contaminants from complex geometries—including blind holes, microchannels, threaded surfaces, and delicate instrumentation components. Operating on the principle of cavitation physics, the unit generates high-frequency (40 kHz) acoustic pressure waves in aqueous or compatible solvent media, inducing controlled microbubble implosion at solid–liquid interfaces. This mechanism delivers mechanical energy sufficient to dislodge sub-micron residues without surface abrasion or thermal degradation—critical for pre-analytical sample preparation in analytical chemistry, semiconductor metrology, medical device reprocessing, and biomaterial cleaning prior to sterilization or coating. Its 15-liter stainless steel tank (330 × 300 × 150 mm internal dimensions) provides scalable capacity for batch processing of multiple small-to-medium parts, glassware, or reusable labware while maintaining uniform energy distribution across the active zone.

Key Features

• Capacitive touchscreen interface with intuitive icon-based navigation, supporting multilingual UI configuration (English, Spanish, German, French) and real-time parameter feedback.
• Pulse-width modulated (PWM) ultrasonic generator enabling precise 40–100% power adjustment—optimized for varying load mass, part geometry, and soil type without frequency drift.
• Integrated degassing mode that automatically cycles ultrasonic output to remove dissolved air from cleaning solutions, ensuring maximal cavitation efficiency before sample immersion.
• Non-heating design compliant with ISO 13847 Annex B for low-thermal-risk applications; eliminates risk of thermal denaturation or solvent volatility during sensitive cleaning protocols.
• Robust 304 stainless steel tank with electropolished interior finish (Ra ≤ 0.4 µm) to inhibit microbial adhesion and facilitate decontamination validation per USP and AAMI ST79.
• Dual-stage safety architecture: real-time current monitoring triggers immediate shutdown upon ground fault detection, while thermistors embedded in transducer housings activate thermal cutoff at ≥85 °C.
• Auto-memory function retains all user-defined parameters—including timer setting, power level, and degas duration—after AC power interruption, eliminating reconfiguration delays between sessions.
• Anti-slip, height-adjustable rubber feet ensure stable operation on uneven lab benches; integrated drain valve enables rapid, spill-free solution exchange without tilting or manual siphoning.

Sample Compatibility & Compliance

The AS15 accommodates a broad spectrum of laboratory substrates including borosilicate glass, fused silica optics, titanium surgical instruments, silicon wafers, ceramic substrates, and polymer-based microfluidic chips. It is validated for use with common aqueous detergents (e.g., Alconox®, Liquinox®), ethanol/water mixtures, and low-surface-tension solvents approved under GHS Category 3 flammability limits. The system meets structural and electrical safety requirements per UL 61010-1 and IEC 61010-1:2010. Its operational repeatability supports routine qualification under GLP and ISO/IEC 17025 frameworks, particularly when paired with documented cleaning validation protocols aligned with ASTM E2889-13 (Standard Guide for Ultrasonic Cleaning Process Validation).

Software & Data Management

While the AS15 operates as a standalone instrument with no external PC dependency, its embedded firmware logs timestamped event data—including total operational hours, number of cleaning cycles executed, and cumulative power-on duration—for internal audit readiness. All user-modifiable settings are stored in non-volatile memory with write-cycle endurance exceeding 100,000 operations. Optional RS-232 serial port (available via accessory module) permits integration into centralized lab equipment monitoring systems for remote status polling and basic command triggering (e.g., start/stop). Data export is not supported; however, the device complies with FDA 21 CFR Part 11 principles through secure parameter locking and operator-level access control via password-protected setup menus.

Applications

• Preparation of HPLC vials, GC autosampler needles, and ICP-MS sample introduction components to eliminate carryover contamination.
• Cleaning of optical lenses, interferometric mirrors, and photomask blanks prior to metrology or thin-film deposition.
• Removal of solder flux residues and oxidation films from printed circuit boards (PCBs) and MEMS assemblies.
• Routine decontamination of reusable pipette tips, centrifuge rotors, and electrophoresis combs in molecular biology labs.
• Supporting ASTM F3250-21 standard practice for ultrasonic cleaning verification in orthopedic implant manufacturing environments.
• Processing of histology cassettes and stainless-steel biopsy forceps in clinical pathology workflows meeting CAP accreditation requirements.

FAQ

Does the AS15 include a heating function?
No. The AS15 is a non-heating ultrasonic cleaner optimized for ambient-temperature cleaning processes where thermal stability is critical.
Is the unit suitable for cleaning delicate electronic components?
Yes—when operated at reduced power levels (40–60%) and with appropriate low-foaming, non-corrosive cleaning solutions, it is routinely used for PCB and semiconductor component cleaning.
Can the AS15 be validated for GMP environments?
Yes. Its consistent cavitation output, traceable power calibration, and built-in safety logging support IQ/OQ/PQ documentation required for regulated pharmaceutical and medical device manufacturing.
What maintenance is required for long-term reliability?
Routine inspection of the drain valve O-ring, periodic descaling of the tank using 5% citric acid solution, and annual verification of transducer impedance (using manufacturer-provided test procedure) are recommended.
Is the touchscreen resistant to common lab disinfectants?
Yes—the Gorilla Glass–reinforced display withstands repeated wiping with 70% isopropyl alcohol, quaternary ammonium compounds, and sodium hypochlorite solutions up to 500 ppm.
