Hanuo HN-6AL Adjustable-Power Ultrasonic Cleaner

Overview

The Hanuo HN-6AL Adjustable-Power Ultrasonic Cleaner is an engineered solution for precision cleaning of delicate laboratory components, optical elements, electronic assemblies, and medical instruments. It operates on the principle of ultrasonic cavitation—generating high-frequency pressure waves (40 kHz) in liquid media that induce microscopic bubble formation and collapse, producing localized energy sufficient to dislodge particulate contaminants, organic residues, oils, fluxes, and biofilms without mechanical abrasion. Designed for routine use in QC labs, R&D facilities, and clinical support environments, this unit delivers reproducible cleaning performance across diverse sample geometries and material classes—including glassware, stainless steel tools, silicone tubing, quartz optics, and SMD substrates—while maintaining structural integrity and surface finish.

Key Features

• Digitally controlled ultrasonic power output (40–100% of 180 W), enabling optimization for sensitive or heavily soiled samples
• Precise temperature regulation from 10 °C to 80 °C via integrated heating element (200 W), supporting enzymatic decontamination, solvent-assisted cleaning, and degassing protocols
• Programmable digital timer (0–30 minutes) with automatic shutdown for unattended operation and process repeatability
• Full SUS304 stainless steel construction—including tank, housing, lid, and mesh basket—ensuring corrosion resistance, cleanability, and compliance with ISO 13485 and GLP environmental requirements
• Acoustically damped hinged lid to reduce ambient noise levels and minimize airborne aerosol dispersion during operation
• Manual fill-and-drain configuration compatible with aqueous solutions, ethanol, isopropanol, and low-surface-tension cleaning solvents approved under REACH and GHS guidelines

Sample Compatibility & Compliance

The HN-6AL accommodates a broad spectrum of laboratory and industrial specimens: volumetric flasks, pipettes, cuvettes, microscope slides, spectrophotometer cells, endoscopic components, dental burs, orthodontic retainers, semiconductor wafers, PCBs, and MEMS devices. Its 6 L capacity and 300 × 150 × 150 mm tank volume permit batch processing of multiple items while preserving uniform acoustic field distribution. The device meets general safety standards per IEC 61010-1 for laboratory electrical equipment and supports validation workflows aligned with ASTM D2603 (ultrasonic cleaning efficacy testing) and USP (cleaning verification of pharmaceutical equipment). While not certified as a sterilizer, it serves as a validated pre-sterilization cleaning step compliant with ISO 17664 and AAMI ST79.

Software & Data Management

This model features embedded microcontroller-based operation with no external software dependency. All parameters—power level, temperature setpoint, and duration—are configured via intuitive front-panel membrane buttons and a backlit LCD display. The system logs no operational data internally; however, its stable analog control architecture ensures consistent parameter retention across power cycles. For laboratories requiring audit trails, integration with external environmental monitoring systems (e.g., via RS232 or optional relay outputs) is feasible through third-party hardware interfaces. The absence of network connectivity aligns with air-gapped lab infrastructure policies and simplifies 21 CFR Part 11 compliance when used in conjunction with paper-based or LIMS-managed procedural documentation.

Applications

• Routine decontamination of glassware and plastic labware prior to calibration or analytical use
• Removal of solder flux, rosin residue, and particulate debris from printed circuit boards and microelectronic components
• Preparation of optical surfaces—including camera lenses, interferometric mirrors, and fiber optic connectors—for metrology-grade inspection
• Cell culture vessel cleaning to eliminate protein adhesion and biofilm precursors before autoclaving
• Support of nanoparticle dispersion and sample homogenization in suspension-based assays
• Ultrasonic degassing of solvents and mobile phases prior to HPLC or GC analysis
• Cleaning of reusable surgical instruments and dental handpieces in accordance with AORN recommended practices

FAQ

Is the HN-6AL suitable for cleaning delicate optical components such as coated lenses or prisms?
Yes—the 40 kHz frequency and adjustable power allow gentle yet effective removal of dust, fingerprints, and thin organic films without damaging anti-reflective or dielectric coatings.
Can this unit be used with flammable solvents like acetone or hexane?
No. The HN-6AL lacks explosion-proof certification and internal ventilation. Only non-flammable, low-volatility solvents (e.g., aqueous detergents, ethanol ≤70%, isopropanol) are permitted.
Does the unit include a built-in drain valve?
No. Drainage is manual via tilting or siphoning; models HN-15AL and above feature integrated drain ports.
What maintenance is required for long-term reliability?
Routine descaling with diluted citric acid solution every 50 operating hours is recommended when using tap water; periodic inspection of transducer adhesion and tank integrity is advised per ISO/IEC 17025 maintenance schedules.
Is calibration documentation provided with shipment?
The unit ships with a factory test report confirming functional verification of timer accuracy, temperature stability (±2 °C at 50 °C), and ultrasonic activation. NIST-traceable calibration services are available upon request.
