Zhongke Aobo CP Series Ultrasonic Cleaner

Overview

The Zhongke Aobo CP Series Ultrasonic Cleaner is a general-purpose laboratory ultrasonic cleaning system engineered for precision, repeatability, and operational safety in routine sample preparation, glassware decontamination, and component surface conditioning. It operates on the principle of cavitation—generated by high-frequency (40 kHz) piezoelectric transducers bonded to the tank bottom—which produces microscopic implosions in the cleaning solution. These transient pressure differentials disrupt particulate adhesion, organic residue, and biofilm layers without mechanical abrasion or thermal degradation. With a validated cleaning efficacy exceeding 98% and uniform energy distribution across the tank volume, this unit meets the functional requirements of ISO 13485-prepared environments and supports GLP-compliant workflows where trace contaminant removal is critical—especially for complex geometries such as pipette tips, microtiter plates, filtration membranes, and precision optical components.

Key Features

• Stainless steel tank (300 × 150 × 150 mm) with corrosion-resistant 304-grade construction and seamless welding for long-term chemical compatibility with aqueous, alkaline, and mild solvent-based cleaning solutions.
• Digital control panel with independent, real-time adjustment of ultrasonic power (10–100% in 10% increments), heating temperature (ambient +5°C to 80°C), and timer (0–80 minutes), enabling method reproducibility across operators and shifts.
• Integrated sound-dampening lid reduces airborne noise to ≤55 dB(A) at 1 m distance—complying with OSHA 29 CFR 1910.95 occupational exposure limits for continuous operation in shared lab spaces.
• Over-temperature protection and auto-shutdown upon lid opening ensure compliance with IEC 61010-1:2010 safety standards for laboratory electrical equipment.
• Manual drain port located at tank base facilitates rapid solution exchange and minimizes cross-contamination risk between cleaning cycles.

Sample Compatibility & Compliance

The CP Series accommodates a broad range of laboratory substrates—including borosilicate glassware, stainless steel tools, aluminum fixtures, ceramic crucibles, and polymer-based consumables—without inducing surface pitting or dimensional distortion under standard operating conditions. It is compatible with common cleaning chemistries approved under ASTM D4305 (Standard Test Method for Cleaning Ability of Solvents) and supports validation protocols aligned with USP “Cleaning and Sterilization” guidelines. While not certified for sterile processing per ISO 11135 or ISO 11137, it serves as a critical pre-sterilization step in GMP-regulated pharmaceutical QC labs and academic research facilities requiring residue-free surfaces prior to analytical instrumentation use (e.g., HPLC vial preparation, SEM stub cleaning).

Software & Data Management

This model operates via embedded firmware without external PC dependency; all parameter settings are retained in non-volatile memory after power cycling. Though no proprietary software interface is provided, the digital display logs setpoints and elapsed time for manual audit trail documentation—a minimal but sufficient configuration for labs operating under basic GLP or ISO/IEC 17025 Clause 7.7 record-keeping requirements. For facilities requiring electronic records compliant with FDA 21 CFR Part 11, integration with third-party lab information management systems (LIMS) is achievable via optional RS-232 or USB-to-serial adapters (sold separately), enabling timestamped export of cycle metadata including start/end time, temperature profile, and power level.

Applications

• Routine decontamination of volumetric flasks, burettes, and graduated cylinders prior to titration or calibration.
• Removal of proteinaceous residues from electrophoresis combs, gel trays, and blotting apparatus.
• Cleaning of reusable filtration housings, syringe filters, and HPLC column frits to restore flow integrity and minimize backpressure drift.
• Preparation of metallographic samples and electron microscopy specimens where particle-free surfaces are essential for imaging fidelity.
• Support of environmental testing workflows—including TSP/PM2.5 filter cleaning—per EPA Method IO-3.2 and ISO 14644-1 cleanroom component maintenance protocols.

FAQ

Is the CP Series suitable for cleaning delicate optics or MEMS devices?
Yes—when operated at reduced power (≤30%) and using low-surface-tension, non-ionic aqueous solutions, the 40 kHz frequency provides gentle yet effective cavitation for sub-micron particle removal without damaging coated lenses or microstructured surfaces.
Does the unit include a heater safety cutoff?
Yes—the integrated thermostat automatically disables heating if internal temperature exceeds 85°C or if the tank is operated empty, preventing dry-run damage and thermal runaway.
Can I use organic solvents such as acetone or isopropanol?
No—this model is rated exclusively for aqueous and water-miscible solutions. Use of flammable solvents violates IEC 61010-1 ignition hazard provisions and voids the safety certification.
What is the expected service life of the transducers under continuous daily use?
Based on accelerated lifetime testing per IEC 60068-2-64, the piezoceramic transducers maintain ≥95% nominal power output after 10,000 hours of operation at 40 kHz and 25°C ambient.
Is calibration documentation provided with shipment?
A factory-issued Certificate of Conformance (CoC) is included, verifying compliance with specified electrical, thermal, and acoustic performance parameters. NIST-traceable calibration certificates are available upon request at additional cost.
