Supmile KQ-2000E Benchtop Ultrasonic Cleaner

Overview

The Supmile KQ-2000E is a high-capacity, general-purpose benchtop ultrasonic cleaner engineered for demanding laboratory, industrial maintenance, and quality control environments. It operates on the principle of cavitation—where high-frequency sound waves (40 kHz) generate microscopic vacuum bubbles in the cleaning solution that collapse with localized energy release, effectively dislodging particulate contaminants, oils, oxides, and biofilms from complex geometries, blind holes, and delicate surfaces. With a 160-liter stainless steel tank constructed entirely from ASTM A240 304-grade stainless steel, the KQ-2000E supports large-volume batch processing of components such as optical lenses, surgical instruments, precision machined parts, printed circuit boards, and ceramic substrates. Its robust 2000 W ultrasonic transducer array delivers uniform energy distribution across the entire tank volume, while the integrated 9000 W heating system enables precise temperature control from ambient up to 80 °C—critical for optimizing detergent activation and solubilizing organic residues.

Key Features

• High-power 2000 W ultrasonic output at 40 kHz frequency, optimized for consistent cavitation intensity and reproducible cleaning efficacy
• Full 304 stainless steel construction—including tank, lid, and structural frame—for corrosion resistance, long-term durability, and compliance with ISO 15190 laboratory safety standards
• Adjustable digital timer with range from 1 minute to 60 minutes, plus continuous operation mode for extended cleaning cycles
• Precise thermostatic control (ambient to 80 °C) with ±2 °C accuracy, supporting temperature-dependent cleaning protocols per ASTM D2616 and ISO 14971 risk management frameworks
• Integrated sound-dampening lid reduces operational noise to ≤65 dB(A) at 1 m distance, meeting OSHA 29 CFR 1910.95 workplace noise exposure guidelines
• Manual inlet and drain valves enable flexible fluid handling without reliance on permanent plumbing; compatible with deionized water, aqueous detergents, and low-volatility solvents
• Mechanical knob-based interface ensures reliability, electromagnetic interference (EMI) immunity, and simplified operation under glovebox or wet-lab conditions

Sample Compatibility & Compliance

The KQ-2000E accommodates a wide range of sample types—including metal alloys, glassware, polymers, ceramics, and composite assemblies—without compromising dimensional integrity or surface finish. Its non-contact cleaning mechanism avoids mechanical abrasion, making it suitable for fragile optics, MEMS devices, and calibration standards. The unit complies with IEC 61000-6-3 (EMC emission limits) and IEC 61000-6-2 (immunity requirements). While not certified for sterile processing per ISO 13485 or FDA 21 CFR Part 820, it supports GMP-aligned cleaning validation when used with documented SOPs, calibrated thermometers, and traceable time/temperature logs. Optional accessories—including stainless steel mesh baskets, ultrasonic booster probes, and degassing modules—extend its adaptability to specialized applications.

Software & Data Management

The KQ-2000E features a hardware-centric, analog-digital hybrid control architecture with no embedded firmware or network connectivity. All operational parameters—time, temperature, and power activation—are set via tactile mechanical dials and monitored using analog gauges and LED indicators. This design prioritizes operational continuity, eliminates cybersecurity vulnerabilities, and ensures uninterrupted functionality during power fluctuations or electromagnetic disturbances common in manufacturing facilities. For laboratories requiring audit trails, external data loggers (e.g., Omega OM-DAQPRO-5300) may be connected to the unit’s PT100 temperature sensor output (0–10 V analog signal) and timer relay contacts to record process variables compliant with GLP Annex 11 and FDA 21 CFR Part 11 data integrity principles.

Applications

• Pre-analytical sample preparation in environmental labs: removal of soil particulates from filtration membranes and sediment cores
• Pharmaceutical equipment cleaning validation: residue removal from stainless steel reactor vessels and filling nozzles prior to swab testing
• Electronics manufacturing: defluxing of PCBAs and ultrasonic-assisted solder paste residue extraction
• Research instrumentation maintenance: cleaning of HPLC injector ports, GC liner inserts, and electron microscope specimen holders
• Aerospace component overhaul: deburring and contaminant removal from turbine blades and fuel system injectors
• Academic teaching labs: standardized demonstration of cavitation physics, surfactant efficiency, and temperature-dependent cleaning kinetics

FAQ

Is the KQ-2000E suitable for use with flammable solvents?

No. The unit is designed exclusively for aqueous and non-flammable cleaning solutions. Its heating element and lack of explosion-proof certification preclude safe operation with alcohols, acetone, or hydrocarbon-based solvents.
Can the ultrasonic power be adjusted in real time?

No. The 2000 W output is fixed at 40 kHz; power modulation is not supported. Intensity control is achieved indirectly via temperature, dwell time, and solution chemistry selection.
What is the expected service life of the transducer array?

Under normal operating conditions and proper solution maintenance (e.g., regular degassing, pH monitoring), the piezoelectric transducers are rated for ≥10,000 hours of cumulative operation.
Does the unit include a built-in degassing function?

No. Degassing must be performed manually by running the unit empty for 5–10 minutes prior to loading samples, or by using an external vacuum degasser.
Is technical support available outside mainland China?

Yes. Supmile provides remote diagnostic assistance and English-language documentation. Spare parts—including transducer modules, heaters, and control panels—are distributed through authorized regional partners in Southeast Asia, the Middle East, and Latin America.
