Supmile KQ3200DM Quiet-Operation Ultrasonic Cleaner

Overview

The Supmile KQ3200DM Quiet-Operation Ultrasonic Cleaner is a benchtop laboratory-grade cleaning system engineered for precision, reliability, and low-noise operation in demanding analytical, quality control, and research environments. It employs high-efficiency piezoelectric ring transducers operating at a fixed frequency of 40 kHz—optimized for broad-spectrum cavitation performance across aqueous and mild solvent-based cleaning media. The device utilizes the principle of acoustic cavitation: ultrasonic energy induces rapid formation and collapse of microscopic vapor bubbles in the cleaning solution, generating localized high-pressure shockwaves that dislodge particulate contaminants, organic residues, and biofilms from complex geometries—including pipette tips, optical lenses, microfluidic chips, surgical instruments, and precision mechanical components. Its robust SUS304 stainless steel tank (300 × 150 × 150 mm internal dimensions), combined with intelligent thermal regulation and real-time frequency tracking, ensures consistent cleaning efficacy across extended operational cycles while maintaining compliance with general laboratory safety and electromagnetic compatibility standards.

Key Features

• Low-noise design with integrated sound-dampening lid, achieving <60 dB(A) during full-power operation—suitable for shared lab spaces and noise-sensitive facilities.
• LCD touch interface enabling intuitive parameter setting for time (0–24 h), temperature (ambient to 80 °C), and ultrasonic power (0–100% in fine increments).
• Advanced transducer control architecture featuring automatic frequency sweeping, real-time frequency tracking, and auto-frequency search—ensuring optimal energy coupling despite solution composition changes or tank loading variations.
• Comprehensive safety system including over-temperature, over-voltage, and over-current protection circuits compliant with IEC 61010-1 requirements for laboratory electrical equipment.
• High-Q piezoelectric ring transducers mounted on the tank bottom provide uniform energy distribution and extended service life under continuous duty cycles.
• Integrated 400 W heating element with PID-controlled thermal regulation supports temperature-assisted cleaning protocols critical for protein removal, wax dissolution, or degassing applications.

Sample Compatibility & Compliance

The KQ3200DM accommodates a wide range of sample types and accessories: standard glassware (beakers, flasks, cuvettes), metal tools (tweezers, forceps, scalpels), ceramic substrates, silicon wafers, and polymer-based microdevices. Its 6 L tank volume supports batch processing of multiple items simultaneously using the included SUS304 mesh basket. While not certified for sterile processing per ISO 13485 or EN 285, the unit meets general-purpose cleaning validation prerequisites outlined in ASTM D4169 and USP for non-sterile equipment decontamination. All materials in contact with cleaning solutions conform to FDA-compliant stainless steel (SUS304) specifications. Electrical design adheres to CE marking directives (EMC Directive 2014/30/EU and Low Voltage Directive 2014/35/EU).

Software & Data Management

The KQ3200DM operates as a standalone instrument without external software dependency. All operational parameters are stored in non-volatile memory and retained after power cycling. The LCD interface logs last-used settings and displays real-time status indicators (temperature, elapsed time, active power level). Though it does not feature USB or Ethernet connectivity, its timer and temperature functions support reproducible protocol execution required for GLP-aligned documentation. For audit-trail purposes, users may manually record cycle parameters in laboratory notebooks or integrate usage logs into LIMS via external time-stamped entries.

Applications

• Pre-analytical sample preparation: removal of residual solvents, fingerprints, or polishing compounds from HPLC vials, GC liners, and spectrophotometer cells.
• Microelectronics: cleaning of PCBs, solder masks, and MEMS devices prior to coating or bonding steps.
• Pharmaceutical QA/QC labs: decontamination of tablet punches, capsule fillers, and stainless-steel contact surfaces between batches.
• Academic research: surface preparation of AFM cantilevers, TEM grids, and electrochemical electrodes.
• Dental and veterinary clinics: adjunctive cleaning of reusable instruments before autoclaving or chemical sterilization.

FAQ

Is the KQ3200DM suitable for use with flammable solvents?
No. This unit is designed exclusively for aqueous or water-miscible solutions. Flammable or highly volatile solvents must not be used due to absence of explosion-proof certification.
Does the unit support remote monitoring or data export?
No. It lacks digital communication interfaces; all operation and monitoring occur locally via the front-panel LCD touchscreen.
What maintenance is required for long-term reliability?
Routine cleaning of the tank interior and mesh basket is recommended after each use. Transducer performance should be verified annually using a calibrated hydrophone or cavitation intensity test kit per ASTM E1755 guidelines.
Can the heating function operate independently of ultrasonic activation?
Yes. Temperature control and ultrasonic generation are decoupled systems—enabling standalone warming or silent soaking protocols.
Is the sound-dampening lid removable for large-item loading?
Yes. The lid is hinged and fully openable, allowing unobstructed access to the tank for oversized or irregularly shaped components.
