Otisience AS10200A Ultrasonic Cleaner

Overview

The Otisience AS10200A Ultrasonic Cleaner is a benchtop, general-purpose ultrasonic cleaning system engineered for precision and reproducibility in routine laboratory cleaning, degassing, and sample preparation workflows. It operates on the principle of piezoelectric transduction at a fixed frequency of 40 kHz, generating high-frequency acoustic pressure waves in liquid media that induce controlled cavitation—microbubble formation and collapse—within the cleaning solution. This physical mechanism effectively dislodges particulate contaminants, organic residues, and loosely adhered biofilms from surfaces of glassware, metal parts, surgical instruments, filters, and small-scale analytical components without mechanical abrasion. Designed for consistent performance across variable load conditions, the AS10200A delivers stable 300 W nominal output power with fine-grained digital control over intensity (30–100% in 10% steps), enabling optimization for delicate substrates (e.g., microfluidic chips, optical lenses) as well as robust items (e.g., stainless-steel forceps, chromatography vials). Its 10 L tank volume supports standard laboratory throughput while maintaining uniform energy distribution across the bath.

Key Features

• Digitally controlled ultrasonic power output (30–100% in precise 10% increments) for process repeatability and material compatibility tuning
• Programmable electronic timer with selectable intervals from 1 to 18 minutes or continuous mode, supporting both standardized cleaning protocols and extended degassing applications
• Sound-dampening hinged lid reduces ambient noise levels to ≤55 dB(A) at 1 m distance, improving ergonomics in shared lab environments
• Corrosion-resistant stainless-steel tank (304 grade) with seamless welds and polished interior surface for long-term chemical resistance and ease of decontamination
• Anodized aluminum housing provides structural rigidity, thermal stability, and electromagnetic interference (EMI) shielding; stainless-steel housing available as factory-configured option
• Integrated manual drain valve with quick-connect fitting enables safe, spill-free solution disposal without tilting or lifting the unit
• Degassing mode activation via dedicated front-panel button initiates low-power, high-cavitation-density cycling to rapidly remove dissolved gases from solvents prior to critical analytical use

Sample Compatibility & Compliance

The AS10200A accommodates a wide range of sample geometries and materials, including but not limited to volumetric flasks, pipette tips, LC vials, HPLC columns (with protective sleeves), ceramic crucibles, and polymer-based microplates. It is compatible with common aqueous and mild organic cleaning solutions (e.g., diluted alkaline detergents, isopropanol/water mixtures, and ethanol-based formulations), though aggressive solvents such as chlorinated hydrocarbons or concentrated acids require verification against tank material compatibility charts. The unit complies with IEC 61010-1:2010 for laboratory electrical equipment safety and meets EMC requirements per IEC 61000-6-3 (emission) and IEC 61000-6-2 (immunity). While not certified for ISO 13485 or FDA 21 CFR Part 11, its design supports GLP/GMP-aligned documentation practices when integrated into validated cleaning SOPs—including operator log entries, time/power parameter recording, and maintenance history tracking.

Software & Data Management

The AS10200A is a standalone analog-digital hybrid instrument with no embedded firmware-based data logging or network connectivity. All operational parameters (power level, timer setting, degas activation) are set manually via tactile membrane switches and displayed on a dual-digit LED screen. For laboratories requiring audit-ready records, integration with external environmental monitoring systems or LIMS is achieved through optional dry-contact relay outputs (available via OEM customization). Routine calibration verification—such as bath temperature stability (if equipped with optional probe), ultrasonic field uniformity mapping, and power output validation—should be performed semiannually using traceable reference standards (e.g., calorimetric power meters per ASTM E1427) and documented per internal QA procedures.

Applications

• Routine cleaning and sterilization pre-treatment of glassware and metallic labware prior to autoclaving or analytical use
• Degassing of mobile phases and solvents for HPLC, UHPLC, and GC systems to minimize baseline noise and bubble-induced pump fluctuations
• Removal of residual proteins, lipids, and nucleic acid fragments from electrophoresis combs, gel trays, and PCR tubes
• Preparation of nanoparticle suspensions and colloidal dispersions by controlled deagglomeration
• Surface activation and contaminant removal from semiconductor wafers, MEMS devices, and optical components during R&D prototyping
• Supporting ISO 17025-accredited testing labs in maintaining traceable, repeatable cleaning steps within method validation packages

FAQ

Is the AS10200A suitable for cleaning delicate optics or microelectronics?
Yes—when operated at 30–50% power with low-surface-tension, non-corrosive solvents (e.g., 2-propanol), it effectively removes submicron particles without scratching. Always verify solvent compatibility with substrate manufacturer specifications.
Can the unit be used for solvent degassing in HPLC mobile phase preparation?
Yes—the dedicated degas mode enhances cavitation efficiency at reduced power, accelerating dissolved air removal. Typical degassing duration is 5–10 minutes per liter of solvent.
Does the AS10200A include temperature control or heating capability?
No—this model lacks integrated heating elements or temperature sensors. For thermally assisted cleaning, external water baths or heated immersion tanks must be used in conjunction.
What maintenance is required to ensure long-term reliability?
Monthly inspection of transducer integrity, quarterly cleaning of tank bottom deposits with citric acid solution, and annual verification of power output stability using calibrated calorimetric methods are recommended.
Is stainless-steel housing available as a standard configuration?
No—it is offered only as a factory-configurable option at time of order; anodized aluminum is the default housing material.
