Shanghai Kedao SK3200HP High-Power Benchtop Ultrasonic Cleaner

Overview

The Shanghai Kedao SK3200HP is a high-power benchtop ultrasonic cleaner engineered for precision cleaning of delicate laboratory components, analytical instrumentation parts, glassware, surgical tools, and small electronic assemblies. It operates on the principle of cavitation—generating microscopic vacuum bubbles in liquid media through high-frequency acoustic energy (53 kHz), which collapse violently to dislodge particulate contaminants, organic residues, and biofilms from surfaces. Unlike lower-frequency systems, the 53 kHz frequency provides an optimal balance between cleaning intensity and surface safety, minimizing erosion risk on sensitive substrates such as optical lenses, microfluidic chips, and coated metal parts. Designed for routine use in QC/QA labs, research facilities, and clinical instrument maintenance workflows, the SK3200HP delivers reproducible cleaning performance without integrated heating—ensuring thermal stability for temperature-sensitive samples and solvents.

Key Features

• Benchtop form factor with compact footprint (330 × 180 × 240 mm) suitable for fume hoods, laminar flow cabinets, or shared lab benches.
• Backlit LCD interface displaying real-time timer countdown, power level (%), and tank water temperature (sensor-integrated, non-heating).
• Fine-grained ultrasonic power control: adjustable from 40% to 100% of nominal 150 W output in precise 1% increments—enabling method optimization for varying soil loads and substrate fragility.
• Digital timer with extended range (1–199 minutes), supporting both short-cycle degassing and prolonged cleaning protocols.
• Stainless steel 304 tank (300 × 150 × 100 mm internal dimensions) with corrosion-resistant finish and seamless construction for long-term solvent compatibility and cleanability.
• Power interruption memory function: automatically resumes pre-set parameters after brief power loss—critical for unattended overnight operation.
• Included stainless steel support rack for uniform sample suspension and consistent exposure to acoustic fields.

Sample Compatibility & Compliance

The SK3200HP accommodates a broad spectrum of sample types including volumetric flasks, pipette tips, HPLC vials, microscope slides, semiconductor wafers (pre-etch), dental instruments, and printed circuit board (PCB) assemblies. Its 4.5 L capacity supports batch processing of up to 20 standard test tubes or six 100 mL beakers simultaneously. The unit complies with IEC 61000-6-3 (EMC emission standards) and meets basic electrical safety requirements per GB 4793.1–2007 (Chinese equivalent of IEC 61010-1). While not certified for ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, its parameter logging capability (via manual recording of LCD-displayed settings) supports GLP-compliant documentation when integrated into validated cleaning SOPs. Users performing regulated cleaning (e.g., USP for pharmaceutical equipment) should validate cycle parameters—including sonication time, power level, and bath temperature—against defined acceptance criteria.

Software & Data Management

The SK3200HP operates via embedded firmware with no external software dependency. All operational parameters are configured directly on the front-panel LCD using intuitive menu navigation. Real-time display includes elapsed time, remaining time, set power percentage, and measured bath temperature (±1 °C accuracy). Though the device lacks USB/RS-232 connectivity or cloud data export, its parameter retention feature ensures traceability across sequential runs. For laboratories requiring audit-ready records, integration with external data loggers (e.g., thermocouple-based bath monitors) and manual entry into ELN systems is recommended. The absence of network interfaces simplifies cybersecurity compliance in GxP environments where isolated instrumentation is preferred.

Applications

• Pre-analytical sample preparation: removal of residual proteins, lipids, or salts from LC-MS autosampler vials and syringe filters.
• Maintenance of optical components: gentle decontamination of cuvettes, fiber optic connectors, and spectrophotometer cells without scratching.
• Microelectronics: particle removal from MEMS devices and solder paste stencils prior to inspection.
• Clinical lab support: cleaning of reusable hematology analyzers’ fluidic manifolds and electrode housings.
• Materials science: debubbling of nanoparticle suspensions and dispersion homogenization in low-viscosity solvents.
• Education labs: standardized demonstration of cavitation physics and cleaning efficiency testing using dye-stained coupons.

FAQ

Does the SK3200HP include a heater?
No. This model is a non-heated ultrasonic cleaner. Bath temperature is monitored but not actively controlled.
Can it be used with flammable solvents?
Only in well-ventilated areas or explosion-proof enclosures. The unit is not intrinsically safe; consult solvent safety data sheets before use.
Is the 53 kHz frequency adjustable?
No. Frequency is fixed at 53 kHz to ensure stable cavitation field generation and transducer longevity.
What is the warranty coverage?
Shanghai Kedao provides a standard 12-month limited warranty covering manufacturing defects in materials and workmanship under normal laboratory use.
How often should the tank water be changed?
Recommended after each cleaning session or when visible contamination accumulates—especially when processing oily or proteinaceous residues.
