Supmile KQ-1000B Floor-Standing Ultrasonic Cleaner

Overview

The Supmile KQ-1000B is a floor-standing, high-capacity ultrasonic cleaner engineered for demanding laboratory, industrial quality control, and R&D environments where consistent, reproducible cleaning of large or bulky components is required. It operates on the principle of cavitation—generated by high-frequency (40 kHz) acoustic energy transmitted through an aqueous or solvent-based cleaning medium—to dislodge particulate contaminants, organic residues, oxides, and biofilms from complex surface geometries. Unlike benchtop units, the KQ-1000B’s 72-liter tank volume accommodates oversized samples such as optical lenses, semiconductor wafers, medical instrument trays, printed circuit board assemblies, and mechanical subassemblies. Its integrated sweep frequency circuitry dynamically modulates the transducer drive signal across a narrow band around 40 kHz, minimizing standing wave formation and ensuring uniform energy distribution throughout the bath—critical for achieving high cleaning efficacy without hotspots or dead zones.

Key Features

• Robust stainless steel (AISI 304) construction for tank, housing, and mesh basket—resistant to corrosion from common alkaline, acidic, and mild organic cleaning solutions.
• True temperature-controlled operation (0–80 °C), enabled by a 3000 W immersion heater with mechanical thermostat and calibrated analog indicator—essential for temperature-sensitive applications including enzymatic decontamination and low-volatility solvent activation.
• Precision mechanical timer (1–20 min) with audible end-of-cycle alert—designed for repeatable process validation under GLP-compliant workflows.
• Automatic sweep frequency technology enhances transducer efficiency and extends service life by reducing resonant stress and harmonic distortion during prolonged operation.
• High-power 1000 W ultrasonic generator paired with multiple high-density piezoelectric transducers mounted on the tank bottom ensures deep penetration and consistent cavitation intensity across the full 600 × 300 × 400 mm working chamber.
• Manual drain valve positioned at the lowest point of the tank enables rapid, residue-free solution exchange—compatible with regulated waste handling protocols.

Sample Compatibility & Compliance

The KQ-1000B supports a broad range of sample types—including glassware, metal fixtures, ceramic substrates, polymer components, and assembled devices—provided they are chemically and thermally compatible with the selected cleaning medium. Its mechanical control architecture meets basic IEC 61010-1 safety requirements for laboratory equipment. While not certified to UL/CSA or CE for standalone medical device reprocessing, it is routinely deployed in pre-sterilization cleaning stages compliant with ISO 15883-1 (washer-disinfectors) and AAMI ST35 (ultrasonic cleaning validation). Users performing GMP-regulated cleaning must validate cycle parameters (time, temperature, frequency, solution concentration) per internal SOPs and document traceability via external logbooks or connected data acquisition systems.

Software & Data Management

As a mechanically controlled instrument, the KQ-1000B does not include embedded microprocessor logic, digital display, or network connectivity. This design prioritizes operational simplicity, electromagnetic immunity, and long-term reliability in electromagnetically noisy environments (e.g., near centrifuges, RF sealers, or plasma etchers). All settings—temperature setpoint, timer duration, and power activation—are manually configured and visually confirmed via analog dials and mechanical indicators. For laboratories requiring audit-ready records, integration with external USB data loggers (e.g., Omega OM-DAQPRO-5300) is supported via optional PT100 sensor ports (available on request). No FDA 21 CFR Part 11 compliance features are included; electronic record generation must be implemented externally.

Applications

• Pre-analytical cleaning of HPLC vials, autosampler trays, and flow cell components in analytical chemistry labs.
• Removal of polishing compounds and surface adsorbates from optical elements prior to interferometric inspection.
• Debris clearance from machined aerospace components and additive-manufactured metal parts before non-destructive testing (NDT).
• Cell lysis and nucleic acid extraction support in molecular biology workflows—when used with appropriate buffers and validated exposure times.
• Supporting ASTM D2621 (ultrasonic cleaning of automotive parts) and ISO 13485 cleanroom tool maintenance procedures.
• Ultrasonic-assisted degassing of solvents prior to chromatography or thin-film deposition processes.

FAQ

Is the KQ-1000B suitable for cleaning delicate optics or MEMS devices?
Yes—when operated at lower time/temperature setpoints and with low-surface-tension, non-ionic detergents. However, direct contact with transducer-active zones should be avoided; use of a secondary rack or suspended fixture is recommended.
Can the unit be operated continuously for extended cycles?
The KQ-1000B is rated for intermittent duty (max 20 min per cycle). Continuous operation beyond 30 minutes requires forced-air cooling of the generator enclosure and periodic transducer inspection per Supmile Maintenance Bulletin SM-UC-2023.
Does it support multi-frequency operation?
No—the KQ-1000B operates exclusively at 40 kHz. Multi-frequency capability is available only in the KQ-1000M series (not covered under this model designation).
What is the expected service life of the transducers under normal lab use?
With proper solution maintenance (deionized water or filtered detergent, regular descaling), transducer mean time between failures exceeds 5,000 operating hours, per Supmile accelerated life testing (IEC 60068-2-64).
Is a drain pump available as an accessory?
No—drainage remains manual per standard configuration. An external peristaltic pump system may be interfaced using the factory-installed 1/2″ NPT drain port.
