Shanghai Kedao SK5200BT Low-Frequency Heated Ultrasonic Cleaner

Overview

The Shanghai Kedao SK5200BT Low-Frequency Heated Ultrasonic Cleaner is a benchtop laboratory instrument engineered for reliable, reproducible cleaning of delicate components, glassware, precision instruments, and small-volume sample containers. Operating at a fixed frequency of 35 kHz, it utilizes low-frequency cavitation physics—characterized by larger, more energetic bubble collapse events—to effectively dislodge particulate contamination, organic residues, and loosely adhered biofilms from surfaces with moderate to high mechanical robustness. The integrated PTC heating system enables precise thermal control between 20 °C and 69 °C, enhancing solvent activity and accelerating dissolution kinetics without compromising temperature-sensitive substrates. Designed for general-purpose use in QC labs, research facilities, and maintenance workshops, the SK5200BT conforms to fundamental functional requirements outlined in ISO 13485 (for medical device reprocessing support), ASTM D2603 (for ultrasonic cleaning validation methodology), and GLP-compliant workflow environments where traceability and operational consistency are essential.

Key Features

• Stable 35 kHz ultrasonic generation via piezoelectric transducers bonded to the bottom of a seamless 304 stainless steel tank—ensuring corrosion resistance, acoustic uniformity, and long-term structural integrity.
• Digital microprocessor-controlled timer (1–99 min) with automatic shutdown and audible end-of-cycle alert—eliminating operator dependency and supporting SOP-driven operation.
• Precise thermostatic regulation with ±2 °C accuracy across the full 20–69 °C range; heating element rated at 270 W for rapid thermal equilibration and stable setpoint maintenance.
• Ergonomic acoustic lid included as standard equipment—reducing ambient noise by ≥15 dB(A) and minimizing solvent evaporation during extended cycles.
• Integrated stainless steel support rack with elevated grid design—optimizing part suspension, maximizing exposure to active cavitation zones, and preventing direct contact between samples and tank bottom.
• Compact footprint (360 × 270 × 310 mm) and lightweight construction (8.6 kg net)—facilitating placement on fume hoods, laminar flow benches, or mobile lab carts without floor reinforcement.

Sample Compatibility & Compliance

The SK5200BT accommodates a broad spectrum of laboratory items including volumetric flasks, pipette tips, crucibles, syringe filters, chromatography vials, optical lenses, and metal calibration standards. Its 10 L tank volume supports batch processing of up to 12 standard 100 mL beakers or 24 × 15 mL centrifuge tubes simultaneously. All wetted parts—including tank, rack, and lid—are fabricated from AISI 304 stainless steel, compliant with FDA 21 CFR §178.3570 for indirect food-contact applications and compatible with common aqueous and mild solvent-based cleaning media (e.g., 1–5% sodium hydroxide, citric acid solutions, isopropanol/water blends). While not certified for sterile processing per ISO 17664 or EN 285, the unit meets baseline electrical safety requirements per IEC 61010-1:2010 and is suitable for non-sterile preparatory cleaning steps within GMP-aligned workflows.

Software & Data Management

The SK5200BT operates via a dedicated front-panel interface with LED display and tactile membrane buttons—designed for intuitive manual operation without external software dependencies. No proprietary drivers, cloud connectivity, or data export functionality are provided, aligning with ISO/IEC 17025 Clause 6.4.7 requirements for equipment used in accredited testing where firmware stability and audit trail simplicity are prioritized over digital integration. All parameter settings (time, temperature) are retained through power cycling, and the absence of internal memory or network interfaces ensures compliance with ITAR-free and air-gapped lab infrastructure policies. For laboratories requiring electronic recordkeeping, external time-lapse logging can be implemented using calibrated external thermometers and stopwatch devices traceable to NIST standards.

Applications

• Pre-analytical preparation of HPLC/GC sample vials and autosampler trays to eliminate carryover and adsorptive artifacts.
• Cleaning of optical components (e.g., cuvettes, microscope slides) prior to spectrophotometric or fluorescence measurements.
• Removal of machining oils and metal fines from precision-engineered parts in materials science and metrology labs.
• Routine decontamination of reusable labware in academic teaching laboratories and industrial R&D centers.
• Supporting ASTM E2983-14 procedures for evaluating cleaning efficacy of medical device components prior to bioburden testing.
• Assisting USP environmental monitoring swab processing by removing particulate interference before microbial enumeration.

FAQ

Is the SK5200BT validated for use in regulated pharmaceutical environments?
It is not supplied with IQ/OQ documentation or 21 CFR Part 11-compliant audit trails. However, its mechanical and thermal parameters are stable and manually verifiable—making it suitable for installation in non-critical cleaning zones under site-specific qualification protocols.
Can this unit operate continuously for extended durations?
Yes—thermal protection circuitry automatically disables heating if internal temperature exceeds safe limits, while ultrasonic transducers are rated for continuous duty at rated power output.
What cleaning solutions are recommended for optimal performance?
Aqueous alkaline detergents (pH 9–11), enzymatic formulations, or low-concentration ethanol/water mixtures are preferred; avoid halogenated solvents or strong acids unless verified compatible with 304 stainless steel.
Does the unit include calibration certificates for temperature or timing functions?
No factory-issued calibration certificates are included; users must perform periodic verification using NIST-traceable thermometers and stopwatches per internal SOPs.
Is remote monitoring or Ethernet connectivity available?
No—the SK5200BT is a standalone analog/digital hybrid instrument with no communication ports, firmware updates, or network interfaces.
