Overview
The Otisience AS5150A is a compact, general-purpose benchtop ultrasonic cleaner engineered for reproducible, non-destructive cleaning of delicate laboratory components—including glassware, pipette tips, chromatography vials, sample holders, and precision metal parts. It operates on the principle of cavitation: high-frequency (40 kHz) acoustic energy induces microscopic bubble formation and collapse within the cleaning solvent, generating localized shockwaves and microstreaming that dislodge particulate contaminants, organic residues, and biofilms without mechanical abrasion. Its 6 L stainless steel tank provides sufficient volume for batch processing of standard labware while maintaining optimal energy density for consistent cleaning efficacy. The unit is designed for routine use in analytical laboratories, QC/QA departments, and research facilities where trace contamination control, instrument maintenance, and sample preparation integrity are critical.
Key Features
- Stable 40 kHz ultrasonic transducer array with 120 W nominal output—delivering uniform energy distribution across the tank bottom for high repeatability
- Adjustable power output (30–100%) to optimize cleaning intensity for sensitive substrates such as coated optics or microfluidic devices
- Digital electronic timer with precise 1–18 minute interval control; supports single-cycle operation without continuous mode (per specification)
- Integrated sound-dampening lid reduces ambient noise to ≤55 dB(A) at 1 m distance—enhancing operator comfort in shared lab spaces
- 304 stainless steel tank with seamless welds and passivated surface finish ensures long-term corrosion resistance against aqueous and mild solvent-based cleaning media
- Anodized aluminum housing provides structural rigidity, thermal stability, and resistance to common lab chemical splashes
- Manual drain valve located at tank base enables rapid, residue-free solvent removal between cleaning cycles
- Dedicated de-gassing function accelerates removal of dissolved air from fresh cleaning solutions—improving cavitation efficiency during initial activation
Sample Compatibility & Compliance
The AS5150A is compatible with water-based detergents, ethanol, isopropanol, acetone, and other low-viscosity solvents commonly used in analytical sample preparation workflows. It is not rated for flammable solvent use without external explosion-proof enclosure. All wetted materials comply with USP Class VI biocompatibility requirements for indirect contact applications. The device conforms to IEC 61000-6-3 (EMC emissions) and IEC 61010-1 (safety for electrical equipment for measurement, control, and laboratory use). While it lacks integrated temperature regulation, its design supports ambient-temperature cleaning protocols aligned with ASTM D4296 (Standard Practice for Ultrasonic Cleaning of Laboratory Glassware) and ISO 15027-1 (Ultrasonic cleaning systems — Part 1: Performance testing methods).
Software & Data Management
The AS5150A operates as a stand-alone hardware system with no embedded firmware or network interface. All controls are implemented via tactile push-button interface with LED status indicators. No software installation, data logging, or audit trail functionality is provided—consistent with its classification as a Class I general-purpose lab utility device under FDA 21 CFR Part 11 interpretation. For labs requiring documented cleaning parameters, users may integrate external timers or environmental monitors compliant with GLP/GMP record-keeping practices. Service logs and calibration verification records are maintained manually per institutional SOPs.
Applications
- Routine cleaning of HPLC vials, GC autosampler inserts, and syringe filters prior to analysis
- Removal of residual solutes and crystalline deposits from quartz cuvettes and optical lenses
- Pre-treatment of metal coupons and calibration standards for surface analysis (e.g., XRF, SEM-EDS)
- Decontamination of reusable electrophoresis combs and gel trays between runs
- Supporting sample prep for ICP-MS and AAS by minimizing trace metal carryover
- Assisting in dissolution testing apparatus maintenance per USP
FAQ
Is the AS5150A suitable for cleaning delicate MEMS devices or semiconductor wafers?
It is not recommended for direct cleaning of unmasked silicon wafers or unprotected MEMS structures due to absence of frequency sweep or pulse modulation features required for ultra-low damage cleaning.
Does the unit include a heater or temperature monitoring capability?
No. The AS5150A operates exclusively at ambient temperature and does not incorporate heating elements or thermal sensors.
Can the timer be bypassed for continuous operation?
No. The digital timer enforces a maximum 18-minute cycle; continuous operation is not supported per current firmware and safety design.
What maintenance is required for long-term reliability?
Monthly inspection of tank integrity, periodic descaling using 5% citric acid solution (if using hard water), and annual transducer impedance verification using a calibrated impedance analyzer are recommended.
Is the unit certified for use in ISO Class 5 cleanrooms?
While constructed with non-shedding materials, it lacks ISO 14644-1 certification for particle generation; placement outside the cleanroom with transfer via pass-through is advised.
