Elma Elmasonic one Compact Ultrasonic Cleaner

Overview

The Elma Elmasonic one Compact Ultrasonic Cleaner is a precision-engineered benchtop ultrasonic cleaning system designed for laboratories, quality control environments, dental practices, jewelry workshops, and research facilities requiring reliable, repeatable removal of particulate contamination from delicate and complex-surface components. Operating on the principle of cavitation—where high-frequency acoustic energy (35 kHz) generates microscopic vacuum bubbles in the cleaning liquid that implode with localized energy—the Elmasonic one delivers consistent mechanical agitation without thermal or chemical aggression. Its compact footprint (236 × 144 × 157 mm), stainless steel tank (194 × 84 × 60 mm internal), and 0.9 L working volume make it ideal for targeted cleaning of small instruments, optical lenses, watch movements, dental prostheses, surgical forceps, and electronic connectors. The unit is engineered for global use with automatic 90–250 V AC input compatibility and conforms to IEC 61000-6-3 (EMC) and IEC 61000-6-2 (immunity) standards.

Key Features

• 35 kHz transducer array with sandwich-type mounting architecture—optimized for uniform energy distribution and effective dislodgement of sub-micron contaminants from crevices, threads, and layered geometries
• Stainless steel tank (AISI 304) with polished interior surface—resistant to corrosion from aqueous and mild solvent-based cleaning solutions
• Digitally controlled timer with LED display: preset intervals from 5 to 30 minutes or continuous operation mode for extended cycles
• Integrated sound-dampening lid—removable and reversible to serve as a drip tray, minimizing lab bench contamination and supporting GLP-compliant workflow hygiene
• Low thermal mass design—no built-in heater; maintains ambient temperature during operation to preserve heat-sensitive substrates (e.g., polymers, adhesives, coated optics)
• Robust power supply with overcurrent and short-circuit protection—certified to UL/EN 61010-1 for laboratory safety compliance

Sample Compatibility & Compliance

The Elmasonic one accommodates a broad range of sample types including metal alloys (stainless steel, titanium, gold), ceramics, glass, acrylics, and silicone-based medical devices. It is routinely employed in pre-sterilization cleaning of Class IIa and IIb medical devices per ISO 15883-1 and supports validation protocols aligned with ISO 13485 quality management systems. While not a sterilizer, its cleaning efficacy meets ASTM F3127 criteria for residual soil removal from reusable surgical instruments prior to autoclaving. The unit is compatible with Elma’s portfolio of GMP-grade, non-ionic, low-foaming cleaning agents (e.g., Elma Clean A, Elma Clean S) formulated for residue-free rinsing and USP particulate matter compliance.

Software & Data Management

As a standalone analog-digital hybrid instrument, the Elmasonic one does not feature embedded software or network connectivity. All operational parameters are set via front-panel controls with real-time LED feedback. However, its deterministic timer behavior and stable frequency output support integration into validated cleaning processes where manual logging (e.g., batch records, SOP adherence checklists) fulfills 21 CFR Part 11 requirements for audit trails. For laboratories operating under GLP or ISO/IEC 17025 accreditation, the device’s repeatability (±2% timer accuracy, ±3% power output stability over 8-hour duty cycle) enables robust method transfer and equipment qualification (IQ/OQ).

Applications

• Precision cleaning of dental prostheses, orthodontic appliances, and endodontic files prior to steam sterilization
• Removal of polishing compounds and organic residues from optical lenses, spectrometer mirrors, and laser components
• Decontamination of microfluidic chips, MEMS sensors, and semiconductor wafers before metrology inspection
• Cleaning of vintage watch parts, gemstone settings, and fine jewelry without surface abrasion or plating damage
• Preparatory cleaning of HPLC injection valves, GC liners, and autosampler vials to prevent carryover artifacts
• Routine maintenance of personal care devices (e.g., electric shavers, hearing aid components) in clinical or industrial hygiene settings

FAQ

Is the Elmasonic one suitable for cleaning heat-sensitive polymer components?
Yes—its non-heated design ensures no thermal stress is applied to thermoplastics, elastomers, or adhesive-bonded assemblies.
Can this unit be used with flammable solvents?
No—only aqueous or water-miscible, non-flammable cleaning solutions are permitted per EN 60079-0 and Elma safety guidelines.
Does the basket meet ISO 15883-5 requirements for medical device reprocessing?
The included 6 × 6 mm mesh basket is compatible with standard reprocessing workflows but requires separate validation for specific device loads per hospital IFU protocols.
What is the expected service life of the transducers under normal lab usage?
With proper solution maintenance and avoidance of dry operation, transducer longevity exceeds 5,000 operating hours, supported by Elma’s 2-year limited warranty.
Is calibration required for routine operation?
No formal calibration is mandated; however, periodic verification of timer accuracy and cavitation activity (e.g., aluminum foil test per ASTM D2299) is recommended for critical applications.
