IRM IDH Series Advanced Ultrasonic Cleaner with Dual-Frequency Operation and Digital Temperature Control

Overview

The IRM IDH Series Ultrasonic Cleaner is an engineered solution for precision cleaning, sample preparation, and auxiliary laboratory processes—including cell disruption, emulsification, dispersion, solvent-assisted extraction, degassing, and acceleration of chemical reactions. Based on the principle of ultrasonic cavitation, the system generates high-frequency mechanical vibrations (33 kHz and 40 kHz) in liquid media, producing transient microbubbles that collapse violently near surfaces—releasing localized energy sufficient to dislodge particulate contaminants, biofilms, and organic residues from complex geometries such as capillaries, porous matrices, and intricate instrumentation components. Unlike single-frequency systems, the IDH series implements synchronized dual-frequency operation to minimize standing-wave dead zones and improve uniformity of acoustic energy distribution across the cleaning bath. Its fully sealed SUS304 stainless-steel tank—formed via one-piece deep-drawing—ensures long-term corrosion resistance, structural integrity, and compliance with ISO 15190:2020 (laboratory safety) and GLP-aligned operational hygiene standards.

Key Features

• Dual-frequency ultrasonic generation (33 kHz + 40 kHz) with independent or interleaved mode selection to eliminate acoustic shadowing and enhance cleaning efficacy on irregular or multi-faceted samples.
• High-efficiency power conversion circuitry (>98% efficiency), minimizing reactive power loss and thermal load on internal electronics—extending mean time between failures (MTBF) and supporting continuous-duty operation.
• Intelligent digital control panel with memory retention: retains last-used temperature, timer, and operating mode settings after power interruption, reducing procedural variability in regulated environments.
• Integrated degassing function: initiates low-power ultrasonic agitation prior to main cycle to remove dissolved air from solvents—critical for achieving reproducible cavitation intensity and avoiding bubble interference during analytical or preparative workflows.
• SUS304 soft-gasketed sound-dampening lid reduces operational noise to ≤55 dB(A) at 1 m distance—meeting WHO-recommended ambient noise thresholds for laboratory workspaces.
• Programmable heating system with PID-controlled thermal regulation (±1.5 °C accuracy) across 0–80 °C range; compatible with aqueous, alcoholic, and mild detergent-based cleaning solutions.
• Configurable waveform output: selectable half-wave or full-wave rectified drive modes—optimized for either gentle surface decontamination or aggressive particulate removal without compromising transducer longevity.
• Sleep-mode activation with one-touch wake-up: automatically enters low-power standby after idle period, reducing standby energy consumption by >70% per IEC 62301:2011 compliance requirements.

Sample Compatibility & Compliance

The IDH series accommodates a broad spectrum of laboratory consumables and instruments—including glassware (vials, cuvettes, pipette tips), metal tools (forceps, scalpels), ceramic substrates, polymer-based microfluidic chips, and delicate optical components. All wetted parts are constructed from medical-grade SUS304 stainless steel (ASTM A240/A240M), certified free of leachable heavy metals per USP and . The unit supports validation protocols aligned with ISO 13485:2016 (medical device manufacturing), ASTM D2603-20 (ultrasonic cleaner performance testing), and EU GMP Annex 15 (qualification of cleaning equipment). Optional accessories—including SUS304 mesh baskets with ergonomic handles and custom-fit rack inserts—are available to maintain spatial separation and prevent cross-contamination during batch processing.

Software & Data Management

While the IDH series operates via embedded microcontroller-based firmware (no external PC dependency), its interface supports audit-trail-capable parameter logging when integrated with third-party Lab Information Management Systems (LIMS) via RS-232 or optional USB-to-serial adapter. Timestamped records include start/stop times, setpoint temperatures, actual bath temperatures (monitored via PT100 sensor), elapsed cycle duration, and selected frequency/power mode—enabling retrospective review for FDA 21 CFR Part 11-compliant electronic records when paired with validated software platforms. Firmware updates are performed via secure bootloader protocol, preserving calibration integrity and ensuring traceability per ISO/IEC 17025:2017 clause 5.9.2.

Applications

• Pre-analytical sample preparation: removal of residual proteins, nucleic acids, or lipids from HPLC autosampler vials, GC inlet liners, and mass spectrometry source components.
• Biological tissue homogenization: controlled lysis of cultured cells and soft tissues under chilled conditions to preserve enzyme activity and antigen integrity.
• Pharmaceutical QA/QC: cleaning of tablet punches, capsule fillers, and dissolution apparatus vessels in accordance with USP and Ph. Eur. 2.6.27.
• Nanomaterial synthesis support: dispersion stabilization of carbon nanotubes, graphene oxide, and metal-organic frameworks in polar solvents.
• Maintenance of optical and metrology equipment: non-abrasive cleaning of interferometer mirrors, laser cavity optics, and coordinate measuring machine (CMM) probes.
• Electronics R&D: residue-free removal of flux agents and solder paste from printed circuit boards (PCBs) prior to SEM imaging or electrical testing.

FAQ

What safety certifications does the IDH series hold?
The unit complies with IEC 61010-1:2010 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and carries CE marking under the Low Voltage Directive (2014/35/EU) and EMC Directive (2014/30/EU). Electrical insulation meets double-insulation Class II requirements.
Can the IDH series be used with flammable solvents?
No. The heater and transducer assembly are not intrinsically safe for use with volatile organic solvents (e.g., acetone, ethanol above 40% v/v, or chlorinated hydrocarbons). Only aqueous or water-miscible, non-flammable cleaning solutions are permitted.
Is calibration documentation provided with shipment?
Yes. Each unit ships with a factory calibration certificate verifying temperature accuracy (±1.5 °C at 25 °C, 50 °C, and 75 °C) and timer deviation (<±0.5% over full range), traceable to NIST-certified reference standards.
How often should the ultrasonic tank be descaled?
In hard-water regions, descaling using 5–10% citric acid solution is recommended every 200 operational hours or quarterly—whichever occurs first—to prevent calcium carbonate buildup that attenuates acoustic transmission.
Does the IDH series support remote monitoring or IoT integration?
Not natively. However, analog voltage outputs (0–5 V) for temperature and timer status are accessible via the rear-panel test port, enabling connection to programmable logic controllers (PLCs) or SCADA systems for centralized lab infrastructure monitoring.
