Shanghai Kedao SK1200BT Low-Frequency Heated Ultrasonic Cleaner

Overview

The Shanghai Kedao SK1200BT Low-Frequency Heated Ultrasonic Cleaner is an entry-level benchtop ultrasonic cleaning system engineered for routine laboratory and light industrial applications requiring reliable particle removal from delicate components. It operates on the principle of cavitation—generated by high-frequency mechanical vibrations transmitted through a liquid medium at 35 kHz—producing microscopic implosions that dislodge contaminants from surfaces without mechanical abrasion. Its integrated heating function (20–69 °C) enhances cleaning efficacy for organic residues, oils, and waxes by reducing solution viscosity and increasing solubility kinetics. Designed for stability and reproducibility in non-GMP environments, the SK1200BT supports standardized cleaning protocols in QC labs, electronics assembly, optical component preparation, and pre-analytical sample handling.

Key Features

• 35 kHz ultrasonic transducer array delivering uniform energy distribution across the 2 L stainless steel tank (304 grade), ensuring consistent cavitation intensity and minimizing dead zones.
• Digital microprocessor-controlled timer (1–99 minutes) with automatic shutdown, enabling precise process repeatability and operator-independent execution.
• Adjustable thermostatic heating system (20–69 °C) with ±2 °C accuracy, facilitating temperature-optimized cleaning cycles for diverse soil types and substrate sensitivities.
• Robust housing and sound-dampening lid reduce ambient noise to <55 dB(A) at 1 m distance, meeting standard laboratory acoustic requirements.
• Compact footprint (180 × 160 × 220 mm) and lightweight design (3 kg net) allow flexible placement on fume hoods, laminar flow benches, or shared instrument carts.
• Included accessories—stainless steel support rack and removable lid—support vertical part orientation and minimize solvent evaporation during extended cycles.

Sample Compatibility & Compliance

The SK1200BT accommodates a broad range of substrates including glassware (vials, cuvettes, pipette tips), metal parts (surgical instruments, watch components), ceramic filters, and silicon wafers. Its low-frequency operation avoids excessive erosion of soft metals or fragile coatings. While not certified for ISO 13485 or FDA 21 CFR Part 11 compliance out-of-the-box, its digital timer and temperature control support documentation of critical cleaning parameters—enabling traceability when integrated into lab-specific SOPs aligned with ISO 17025 or GLP frameworks. The 304 stainless steel tank meets ASTM A240 standards for corrosion resistance in aqueous cleaning solutions.

Software & Data Management

The SK1200BT operates via embedded firmware with no external software dependency. All operational parameters—including set temperature, elapsed time, and power status—are displayed on a dual-digit LED interface. No data logging, USB export, or network connectivity is provided; however, manual recording of cycle settings satisfies basic audit requirements for non-regulated environments. For labs requiring electronic records, integration with external environmental monitoring systems (e.g., via relay-triggered signal output) is feasible using third-party I/O modules.

Applications

• Routine cleaning of analytical glassware prior to HPLC, GC, or spectrophotometric analysis.
• Decontamination of reusable pipette tips, centrifuge tubes, and microtiter plates in molecular biology workflows.
• Removal of flux residues and particulate debris from printed circuit boards (PCBs) and semiconductor test fixtures.
• Preparation of optical lenses, mirrors, and fiber optic connectors where surface integrity must be preserved.
• Supporting ASTM D2240 (durometer calibration) and ISO 8502-3 (surface cleanliness assessment) sample conditioning steps.

FAQ

Is the SK1200BT suitable for use with flammable solvents?
No. The device lacks explosion-proof certification and should only be operated with aqueous or non-volatile, low-flashpoint cleaning solutions.
Can the unit be used without heating?
Yes. The heater can be disabled independently while maintaining ultrasonic operation at ambient temperature.
What is the recommended cleaning solution for general-purpose use?
A 1–2% concentration of non-ionic, low-foaming detergent (e.g., Alconox® Liquinox® or Tergazyme®) in deionized water is optimal for most applications.
Does the unit include a degas function?
No. Degassing must be performed manually by running the unit empty for 5–10 minutes before loading samples.
Is calibration documentation provided with the instrument?
Factory calibration certificates are not included; users should perform periodic verification of temperature and timer accuracy per internal quality procedures.
