Supmile KQ-AS2000VDE Floor-Standing Triple-Frequency Ultrasonic Cleaner

Overview

The Supmile KQ-AS2000VDE is a floor-standing, triple-frequency ultrasonic cleaner engineered for high-reproducibility cleaning across diverse sample types and contamination profiles. Unlike single-frequency systems, it employs synchronized switching between three discrete ultrasonic frequencies—45 kHz, 80 kHz, and 100 kHz—enabling optimized cavitation energy distribution across varying particle sizes, surface geometries, and contaminant adhesion mechanisms. At 45 kHz, the system delivers higher cavitation intensity suitable for robust macro-particulate removal; at 80 kHz, it balances penetration depth and micro-cavitation density for general-purpose cleaning; and at 100 kHz, it generates finer, more uniform bubble collapse ideal for delicate substrates and sub-micron residue removal. This frequency-agile architecture eliminates cleaning blind spots and mitigates standing-wave artifacts common in fixed-frequency tanks, particularly in large-volume (160 L) applications where acoustic field homogeneity is critical. The unit complies with IEC 61000-6-3 (EMC emission limits) and incorporates stainless-steel VDE-series construction (304 SS tank, lid, basket, and chassis) to ensure long-term corrosion resistance in aqueous and mild solvent environments.

Key Features

• Floor-standing ergonomic design with reinforced steel frame and casters for stable operation and repositioning in shared lab spaces.
• Triple-frequency digital generator with programmable auto-switching intervals (1–999 s per frequency), enabling sequential or alternating mode execution without manual intervention.
• Full digital control interface with real-time display of temperature, elapsed time, active frequency, power level, and solvent level (1–300 mm adjustable via integrated ultrasonic liquid-level sensor).
• Electrically actuated inlet and drain valves supporting automated fill-and-drain cycles—compatible with centralized lab water supply and waste management systems.
• Integrated solvent filtration module (AS-series specific) with replaceable particulate filter cartridge, extending bath life and reducing maintenance frequency during extended operation.
• Thermal insulation layer beneath the tank and sound-dampening lid reduce ambient noise to ≤65 dB(A) at 1 m and minimize heat loss during heated cycles.
• Over-temperature, dry-run, and over-current protection circuits conforming to IEC 61000-4-5 surge immunity standards.

Sample Compatibility & Compliance

The KQ-AS2000VDE accommodates a broad range of sample formats—including glassware (vials, flasks, cuvettes), metal components (surgical instruments, precision fixtures), ceramic substrates, and polymer-based devices—without requiring dedicated cleaning stations. Its large 800 × 500 × 400 mm internal tank volume supports batch processing of multiple racks simultaneously. All wetted surfaces meet ASTM A240 Type 304 stainless-steel specifications. While not certified for ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, the system’s audit-ready digital log (timestamped parameter records, frequency switching events, and thermal profiles) supports GLP/GMP-aligned documentation when integrated into validated lab workflows. It is routinely deployed in QC labs adhering to USP (Ultrasonic Cleaning of Pharmaceutical Equipment) and ISO 14040-compliant environmental testing facilities.

Software & Data Management

The embedded microcontroller stores up to 99 user-defined cleaning protocols, each configurable with independent settings for frequency sequence, dwell time per frequency, power percentage, heating ramp rate, and final hold temperature. Parameter changes are logged with timestamps and operator ID (via optional RFID badge integration). USB-C port enables export of CSV-formatted session logs for traceability and statistical process analysis. No cloud connectivity or proprietary software installation is required—operation remains fully self-contained and offline-capable to meet data sovereignty requirements in regulated environments.

Applications

• Pre-analytical preparation of HPLC vials, GC autosampler trays, and ICP-MS sample introduction components.
• Removal of polishing compounds, oxides, and organic residues from optical lenses, semiconductor wafers, and MEMS assemblies.
• Extraction support for botanical matrices and tissue homogenates under controlled thermal-ultrasonic conditions.
• Dispersing nanomaterials (e.g., graphene oxide, TiO₂ nanoparticles) in aqueous or ethanol suspensions with reduced agglomeration.
• De-gassing solvents prior to chromatographic use or electrochemical cell filling.
• Validation of cleaning efficacy per ASTM F3255-20 (Standard Guide for Ultrasonic Cleaning Process Validation in Medical Device Manufacturing).

FAQ

Does the KQ-AS2000VDE support frequency-synchronized heating?
Yes—temperature ramping and stabilization occur concurrently with ultrasonic activation, with independent PID control ensuring ±1.5 °C accuracy across the 10–80 °C range.
Can the filtration module handle chlorinated solvents?
The standard AS-series filter housing is rated for aqueous and alcohol-based solutions; for chlorinated or highly aggressive solvents, optional PTFE-lined filter cartridges must be specified at order.
Is remote monitoring or Ethernet connectivity available?
No native Ethernet or Wi-Fi interface is provided; however, the USB-C data export function enables periodic synchronization with local LIMS or ELN platforms via scripted batch transfers.
What safety certifications does the unit carry?
It bears CE marking per Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU, with test reports available upon request for EN 61000-6-2 (immunity) and EN 61000-6-4 (emissions).
How is acoustic uniformity verified in the 160 L tank?
Supmile provides a calibration certificate documenting aluminum foil erosion test results at nine standardized positions (per ASTM D2603-18 Annex A1), confirming ≥85% spatial coverage of effective cavitation intensity.
