Overview
The Elma Elmasonic X-tra pro Flex is a modular, high-flexibility ultrasonic cleaning system engineered for precision laboratory, R&D, and industrial maintenance applications where reproducible, process-controlled cleaning is critical. Based on Elma’s proven Couette-flow-compatible transducer architecture and dual-frequency piezoelectric generation (25 kHz and 45 kHz), the system delivers controlled cavitation energy optimized for both macro-debris removal and micro-contaminant elimination. Unlike fixed-frequency cleaners, the X-tra pro Flex leverages real-time frequency sweep modulation—dynamically varying the drive signal across a narrow bandwidth—to homogenize acoustic pressure distribution within the tank, eliminating standing-wave nodes and minimizing cleaning blind spots. This principle ensures uniform energy delivery across complex geometries, including blind holes, threaded surfaces, and microstructured components. Designed and manufactured in Germany under DIN EN ISO 9001:2015 certified processes, each unit carries the “Made by Elma Germany” designation—a mark of mechanical robustness, long-term thermal stability, and adherence to EU Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU.
Key Features
- Dual-frequency operation (25 kHz for heavy particulate removal; 45 kHz for delicate substrates and fine particulate dispersion)
- Sweep mode: Continuous ±1 kHz frequency modulation to prevent node formation and ensure consistent cavitation density
- Pulse mode: Temporarily boosts effective acoustic power to 120% for recalcitrant residues without thermal overload
- Integrated degassing function: Accelerates solvent deaeration prior to cleaning cycle initiation, improving cavitation efficiency
- Programmable temperature control (30–80 °C) with thermal-activation logic—ultrasound initiates only after setpoint stabilization
- Overtemperature safety cutoff at >90 °C, independent of main controller, compliant with IEC 61000-6-2 immunity requirements
- Low-level fluid sensor with fail-safe interlock: Halts operation if bath volume falls below minimum operational threshold
- Motorized oscillation module (optional): Provides synchronized lateral motion during sonication to enhance mass transfer at solid–liquid interfaces
- Five-language graphical interface (English, German, French, Spanish, Chinese) with five fully customizable protocol slots
- Sound-dampened hinged lid meeting ISO 717-1 noise emission standards (≤65 dB(A) at 1 m)
Sample Compatibility & Compliance
The X-tra pro Flex accommodates a broad range of sample types—from stainless-steel surgical instruments and optical lens assemblies to printed circuit boards (PCBs), MEMS devices, and pharmaceutical vial trays—without risk of surface erosion or micro-pitting when operated within recommended parameters. All wetted parts are constructed from AISI 316L stainless steel, compatible with aqueous alkaline, neutral, and mild acidic cleaning chemistries per ASTM D2616 and ISO 15877. The system supports GLP/GMP-aligned documentation via optional Ethernet or RS-232 connectivity (not included standard), enabling integration into audit-trail-capable environments. While not intrinsically rated for hazardous area use, its electrical design conforms to UL 61010-1 and EN 61010-1 for laboratory equipment safety.
Software & Data Management
The onboard firmware supports full parameter logging—including actual temperature, elapsed time, frequency mode, power output %, and fault codes—for each executed cycle. Data export is available via USB flash drive (FAT32 formatted) in CSV format for traceability and quality review. Optional Elma CleanControl software (v3.2+) enables remote configuration, batch protocol deployment, and trend analysis of cleaning performance metrics across multiple units. Audit trail functionality—including user login, parameter changes, and cycle execution timestamps—is available when paired with Elma’s network-enabled controller upgrade kit, satisfying FDA 21 CFR Part 11 requirements for electronic records and signatures in regulated labs.
Applications
This modular platform serves as a scalable cleaning core in diverse technical environments: QC laboratories validating cleaning efficacy per ISO 14971; medical device reprocessing facilities complying with AAMI ST79 and EN ISO 15883; semiconductor packaging lines requiring particle-free leadframe preparation; optics manufacturing cleanrooms adhering to ISO 14644-1 Class 5 protocols; and academic research groups performing surface science prep for XPS or AFM analysis. Its configurable architecture allows seamless integration of rinse tanks with DI water conductivity monitoring, hot-air drying modules with HEPA-filtered airflow, and programmable lift mechanisms for basket-based batch handling—all controllable through unified sequencing logic.
FAQ
Is the X-tra pro Flex suitable for cleaning heat-sensitive polymer components?
Yes—when operated at 45 kHz with temperature set ≤45 °C and pulse mode disabled, it delivers gentle yet effective cleaning for acrylics, polycarbonates, and PTFE without thermal distortion.
Can the system be validated for ISO 13485-compliant medical device cleaning processes?
Yes—the modular design, programmable repeatability, and optional data logging support IQ/OQ/PQ protocol development; validation kits and qualification templates are available from Elma Technical Services.
What maintenance intervals are recommended for transducer longevity?
Transducers require no scheduled replacement under normal use; annual verification of impedance matching and coolant flow (in water-cooled variants) is advised per Elma Service Bulletin SB-XTP-2023-01.
Does the system support external trigger input for synchronization with robotic handlers?
Yes—via opto-isolated digital I/O port (24 V DC), enabling Start/Stop and status feedback integration with PLC-controlled automation cells.
Are custom tank geometries or material linings available?
Yes—Elma Engineering offers bespoke stainless-steel tank fabrication, including tapered bottoms, integrated filtration ports, and titanium-clad ultrasonic radiating surfaces upon request.
