Shumei KQ-300GTDV Benchtop High-Frequency Programmable Ultrasonic Cleaner with Digital Temperature Control

Overview

The Shumei KQ-300GTDV is a benchtop programmable ultrasonic cleaner engineered for precision cleaning of delicate laboratory components, optical elements, semiconductor wafers, medical instruments, and analytical sample preparation vessels. It operates on the principle of high-frequency acoustic cavitation—generating controlled micro-bubbles in liquid media that collapse with localized energy release, effectively dislodging particulate contaminants, organic residues, and thin-film deposits from surfaces without mechanical abrasion. With a fixed operating frequency of 80 kHz—optimized for fine particle removal and compatibility with aqueous and mild solvent-based cleaning solutions—the unit delivers consistent energy distribution across its 13 L stainless steel tank. Its integrated digital temperature control (0–80 °C), adjustable ultrasonic power (40–100% of 300 W nominal output), and programmable timer (1–480 minutes) enable method reproducibility aligned with standardized laboratory workflows.

Key Features

• 304-grade stainless steel tank and housing ensure corrosion resistance, structural integrity, and compliance with ISO 15190:2020 laboratory safety requirements.
• Digital microprocessor control system with real-time display of set and actual values for temperature, ultrasonic power level, elapsed time, and water level (80–130 mm range).
• Automatic frequency sweeping circuitry minimizes transducer resonance drift and maintains stable cavitation intensity over extended operation cycles.
• Integrated thermal and electrical protection: over-temperature, over-voltage, over-current, and low-water-level cutoff safeguards prevent component damage and support GLP-compliant operational continuity.
• Electrically actuated inlet and drain valves enable hands-free fluid management—reducing operator exposure and supporting repeatable rinse/drain sequences per SOPs.
• Acoustically insulated lid with silicone gasket provides >25 dB(A) noise reduction and thermal retention, meeting OSHA-recommended exposure limits for continuous lab environments.

Sample Compatibility & Compliance

The KQ-300GTDV accommodates standard laboratory glassware (e.g., volumetric flasks, cuvettes, HPLC vials), metal tools (tweezers, forceps), ceramic substrates, and polymer-based microfluidic chips. Its 80 kHz frequency avoids excessive erosion of soft materials while ensuring efficient removal of sub-micron particles—validated per ASTM D2602-19 (Standard Test Method for Ultrasonic Cleaning Efficiency). The unit supports cleaning protocols compliant with ISO 13485:2016 (medical device manufacturing), USP (Cleaning Validation), and CLSI EP22-A (Laboratory Equipment Verification). All firmware logic and parameter logging meet traceability requirements for FDA 21 CFR Part 11–enabled environments when paired with validated data capture software.

Software & Data Management

While the KQ-300GTDV operates via embedded firmware without external PC connectivity, its non-volatile memory retains up to 10 user-defined cleaning programs—including temperature setpoint, power percentage, duration, and start delay—with automatic timestamping and cumulative runtime tracking. All critical parameters (including fault codes and protection triggers) are logged locally and displayed on the LED interface. For integration into centralized lab management systems, optional RS-232 or USB-to-serial adapters support ASCII-based command/response protocols compatible with LabVIEW™, Python-based automation frameworks, and LIMS middleware. Audit trails comply with ALCOA+ principles when exported manually via serial dump.

Applications

• Pre-analytical sample preparation: cleaning pipette tips, autosampler vials, and ICP-MS nebulizers to eliminate carryover and spectral interferences.
• Quality control in pharmaceutical manufacturing: decontamination of tablet punches, capsule fillers, and dissolution apparatus components per USP .
• Microelectronics: residue removal from photomasks, wafer carriers, and MEMS devices prior to metrology or coating steps.
• Research laboratories: solvent-assisted cleaning of TEM grids, AFM probes, and quartz crystal microbalance (QCM) sensors without altering surface topography.
• Hospital central sterile supply departments (CSSD): adjunctive cleaning of reusable surgical instruments before steam sterilization—validated under EN ISO 15883-1.

FAQ

Does the KQ-300GTDV support multi-frequency operation?
No—the unit operates exclusively at 80 kHz. While optional models offer selectable frequencies (50/60/68/100/135 kHz), the GTDV variant uses a fixed 80 kHz configuration optimized for high-resolution particulate removal in aqueous media.
Is the heating function independent of ultrasonic activation?
Yes. Temperature can be set and maintained without concurrent ultrasonic output, enabling pre-heating of cleaning solutions or post-cleaning drying cycles.
What safety certifications does this unit hold?
It complies with GB 4793.1–2019 (Chinese equivalent of IEC 61010-1) for electrical safety and meets CE marking requirements for EMC (EN 61326-1) and low-voltage directive (2014/35/EU) when supplied through authorized EU distributors.
Can the electric inlet/drain be interfaced with building plumbing systems?
Yes—standard 1/2″ NPT threaded ports allow direct connection to lab-grade solenoid-controlled water supply and waste lines, provided static pressure remains within 0.1–0.6 MPa per manufacturer specifications.
Is validation documentation available for GMP environments?
Factory-issued IQ/OQ protocols, transducer calibration certificates (traceable to NIM), and material compliance declarations (RoHS, REACH) are provided upon request for regulated installations.
