Supmile KQ-1500E Benchtop Ultrasonic Cleaner

Overview

The Supmile KQ-1500E is a heavy-duty, general-purpose benchtop ultrasonic cleaner engineered for consistent, high-efficiency removal of particulate contaminants, organic residues, and light oxides from laboratory glassware, precision metal parts, optical components, and medical instruments. It operates on the principle of acoustic cavitation—where high-frequency (40 kHz) ultrasonic energy generates microscopic vacuum bubbles in the cleaning solution that rapidly collapse, producing localized shockwaves and microstreaming forces capable of dislodging sub-micron debris from complex geometries and blind holes. Designed for sustained operation in QC labs, R&D facilities, and sterilization support units, the KQ-1500E features a robust 112-liter stainless steel tank (700 × 400 × 400 mm internal), industrial-grade transducer array, and integrated heating system delivering precise thermal control from ambient temperature up to 80 °C—enabling optimized cleaning performance across aqueous, alkaline, and mild solvent-based solutions.

Key Features

• 1500 W nominal ultrasonic power output with uniform energy distribution across the full tank volume, ensuring reproducible cleaning efficacy in large-batch processing.
• Temperature-regulated heating system (6000 W) with digital setpoint control (RT–80 °C) and ±1 °C stability, supporting temperature-dependent cleaning protocols aligned with ASTM D4169 and ISO 15883-5 standards.
• Mechanical timer with selectable duration (1–60 minutes) and continuous mode—designed for operator simplicity and long-term reliability without software dependencies.
• Full 304 stainless steel construction (tank, lid, frame), including corrosion-resistant transducer mounting and sealed electrical compartments compliant with IP54 ingress protection.
• Included sound-dampening lid reduces operational noise to ≤65 dB(A) at 1 m distance, meeting occupational safety guidelines per OSHA 29 CFR 1910.95.
• Manual inlet and drain valves enable flexible integration into lab water management workflows; compatible with deionized, distilled, or detergent-enhanced solutions.

Sample Compatibility & Compliance

The KQ-1500E accommodates a broad range of sample types—including volumetric flasks, chromatography vials, syringe filters, surgical forceps, endoscopic channels, and semiconductor wafers—without risk of surface erosion or dimensional distortion under standard operating conditions. Its non-aggressive, non-contact cleaning mechanism preserves calibration integrity of metrology tools and avoids mechanical abrasion common in brush-based methods. The unit conforms to key regulatory expectations for equipment used in GLP-compliant laboratories (OECD Principles of GLP, Annex III) and supports traceable process documentation when paired with external loggers. While not certified for sterile processing per ISO 17664, it serves as a validated pre-sterilization cleaning step in GMP environments where residual bioburden reduction is required prior to autoclaving or ethylene oxide treatment.

Software & Data Management

As a mechanically controlled instrument, the KQ-1500E does not incorporate embedded firmware, network connectivity, or digital data logging—intentionally eliminating cybersecurity vulnerabilities and reducing validation overhead in regulated settings. All operational parameters (time, temperature) are set via tactile dials with physical position feedback, enabling straightforward IQ/OQ execution and minimizing electronic audit trail requirements. For labs requiring electronic records, external USB or RS-485-compatible temperature/time loggers can be deployed alongside the unit to capture time-stamped process data compliant with FDA 21 CFR Part 11 when configured with appropriate access controls and electronic signature workflows.

Applications

• Pre-analytical preparation of HPLC/GC sample vials and autosampler components to eliminate carryover and baseline noise.
• Decontamination of reusable pipette tips, centrifuge rotors, and electrophoresis tanks in molecular biology labs.
• Removal of polishing compounds and flux residues from precision optics and MEMS devices prior to coating or assembly.
• Supporting ASTM E1667 and USP cleaning validation studies through repeatable parameter control and documented thermal profiles.
• Routine maintenance of dental handpieces, orthopedic implants, and laparoscopic instruments in hospital central supply departments.

FAQ

Is the KQ-1500E suitable for cleaning delicate optical lenses?

Yes—when operated with low-surfactant, non-ionic aqueous solutions at 35–45 °C and 3–5 minute cycles, it effectively removes fingerprint oils and dust without damaging anti-reflective coatings.
Can the unit be used with flammable solvents?

No—this model is designed exclusively for aqueous and water-miscible solutions. Use only in well-ventilated areas and never with acetone, ethanol, or chlorinated hydrocarbons due to lack of explosion-proof certification.
What maintenance is required for long-term reliability?

Routine inspection of the stainless steel tank for pitting, periodic descaling using 5% citric acid solution, and verification of transducer adhesion integrity every 6 months—per manufacturer-recommended PM schedule.
Does the unit include a degassing function?

No—degassing must be performed manually by running the unit empty for 5–10 minutes before introducing samples, or by applying vacuum-assisted solution preparation externally.
Is calibration documentation provided with shipment?

A factory-issued Certificate of Conformance (CoC) is included, listing measured ultrasonic power output, temperature accuracy verification, and dimensional compliance—sufficient for initial IQ documentation in non-GxP environments.
