Otisence AS5150BD Dual-Frequency Ultrasonic Cleaner

Overview

The Otisence AS5150BD is a dual-frequency benchtop ultrasonic cleaner engineered for precision cleaning of delicate laboratory components, analytical instrumentation parts, glassware, surgical tools, and microfabricated substrates. It operates on the principle of acoustic cavitation—where high-frequency sound waves generate microscopic vacuum bubbles in the cleaning solvent that rapidly collapse, producing localized shockwaves and microstreaming forces capable of dislodging particulate contaminants, organic residues, and weakly adhered biofilms without mechanical abrasion. Its dual-frequency capability (40 kHz and 60 kHz) allows users to optimize cleaning efficacy based on substrate geometry, contaminant type, and material sensitivity: 40 kHz delivers higher energy density and stronger cavitation intensity—ideal for robust items with heavy or tenaciously bonded soils—while 60 kHz provides finer, more uniform energy distribution with reduced noise emission and improved penetration into narrow channels, blind holes, and intricate surface topographies.

Key Features

• Dual-frequency operation (40 kHz / 60 kHz) with manual selection via front-panel switch for application-specific optimization
• Digitally controlled ultrasonic power output (180 W total), continuously adjustable from 1% to 100% to prevent sample damage during sensitive cleaning protocols
• Independent digital timer with dual-line LED display: one line shows preset duration (1–999 minutes), the other displays real-time elapsed time—enabling precise process repeatability and documentation
• Programmable temperature control (RT + 5 °C to 80 °C) with PID-based regulation for enhanced solvent activity and residue solubilization, particularly critical when using aqueous or mild alkaline solutions
• Integrated sound-dampening lid reduces ambient noise by ≥15 dB(A) and minimizes solvent evaporation during extended cycles
• Benchtop stainless steel tank (300 × 150 × 150 mm internal dimensions) ensures chemical resistance, structural rigidity, and long-term dimensional stability under thermal cycling
• Manual drain valve located at tank base enables safe, controlled solvent removal without tilting or lifting the unit

Sample Compatibility & Compliance

The AS5150BD accommodates a broad range of laboratory-compatible materials including borosilicate glass, fused silica, stainless steel, titanium alloys, anodized aluminum, and most thermoplastics (e.g., PTFE, PP, PC). It is routinely deployed in environments requiring adherence to ISO 13485 cleanroom maintenance procedures, ASTM D2603 (ultrasonic cleaning validation), and CLSI GP26-A4 guidelines for reprocessing reusable medical devices. While not certified to FDA 21 CFR Part 11 out-of-the-box, its digital timer and temperature logging support GLP-compliant record-keeping when paired with external audit-trail-capable data loggers. The unit complies with IEC 61000-6-3 (EMC emissions) and IEC 61010-1 (safety requirements for electrical equipment used in laboratory environments).

Software & Data Management

The AS5150BD operates via embedded firmware with no external software dependency. All operational parameters—including frequency selection, power level, set temperature, and timer value—are stored in non-volatile memory and retained after power cycling. Though it lacks USB or Ethernet connectivity, its dual-line digital interface enables unambiguous parameter verification prior to cycle initiation—a critical feature for SOP-driven workflows in QC/QA laboratories. For facilities requiring electronic batch records, integration with third-party SCADA or LIMS platforms is achievable via optional analog voltage outputs (0–10 V) for temperature and timer status signals (available upon request with OEM configuration).

Applications

• Cleaning HPLC/GC autosampler vials, syringe filters, and column frits prior to reuse or calibration
• Removing polishing compounds and oxide layers from optical lenses and semiconductor wafers
• Decontaminating pipette tips, centrifuge rotors, and electrophoresis combs in molecular biology labs
• Pre-cleaning surgical instruments and dental handpieces in accordance with AAMI ST79 and EN ISO 15883 standards
• Preparing TEM grids and AFM cantilevers for high-resolution imaging by eliminating hydrocarbon adsorption and particulate artifacts
• Routine maintenance of viscometers, rheometers, and particle size analyzers where solvent residue compromises measurement accuracy

FAQ

Is the AS5150BD suitable for cleaning delicate MEMS devices or microfluidic chips?

Yes—when operated at 60 kHz with ≤30% power and low-temperature aqueous surfactant solutions, it achieves effective particulate removal while minimizing risk of stiction or structural resonance-induced damage.
Can the unit maintain stable temperature across the full 1–999 minute timer range?

Yes—the PID-controlled heating system compensates for ambient fluctuations and maintains ±1.5 °C accuracy over the entire operating window, verified per ASTM E2209 calibration protocol.
Does the stainless steel tank resist corrosion from common cleaning solvents such as isopropanol or dilute NaOH?

The 304-grade stainless steel construction resists short-term exposure to IPA, ethanol, and ≤2% w/w sodium hydroxide; prolonged use of strong alkalis or halogenated solvents requires periodic inspection per ASTM A967 passivation verification.
Is the drain valve compatible with standard laboratory waste collection systems?

The 1/4″ NPT male thread outlet accepts standard polypropylene or PTFE-lined tubing and connects directly to acid-resistant waste carboys or neutralization traps.
What safety certifications does the AS5150BD carry for international deployment?

It bears CE marking per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), and conforms to RoHS 2011/65/EU. UL/cUL listing is available under custom order with additional safety interlock hardware.
