HengAo HU Series USP/ChP-Compliant Ultrasonic Cleaner & Extractor

Overview

The HengAo HU Series Ultrasonic Cleaner & Extractor is an engineered solution designed explicitly to meet the methodological and procedural requirements outlined in the latest editions of the Chinese Pharmacopoeia (ChP) and aligned with internationally referenced ultrasonic extraction protocols—including those cited in USP “Ultrasonic Cleaning” and ICH Q5C stability guidance for pharmaceutical sample preparation. This system operates on the physical principle of acoustic cavitation: high-frequency mechanical vibrations (40 kHz nominal) generate transient microbubbles in liquid media that collapse violently, producing localized shockwaves, microstreaming, and intense shear forces. These phenomena facilitate rapid mass transfer across solid–liquid interfaces—enabling efficient cell wall disruption, solvent penetration, and solute release from botanical matrices without thermal degradation or chemical alteration. Unlike general-purpose cleaners, the HU Series integrates pharmacopeial-grade parameter control (temperature, time, power, and frequency stability) to ensure reproducible, auditable, and compliant sample preparation workflows in QC laboratories, R&D centers, and GMP-regulated environments.

Key Features

• Pharmacopeia-aligned operation: Pre-configured parameter ranges conform to ChP 2020/2025 and USP recommendations for ultrasonic extraction of herbal powders, tablets, and raw botanicals.
• Full parametric control: Independent adjustment of ultrasonic power (0–100%), bath temperature (0–95 °C ±1.5 °C), and cycle duration (0–99 min) with digital PID regulation and real-time feedback.
• Dual-frequency option (optional): Selectable 40/80 kHz switching enables comparative studies on frequency-dependent extraction efficiency—critical for optimizing recovery of thermolabile alkaloids, flavonoids, or polysaccharides.
• Robust construction: Housing fabricated from imported brushed 304 stainless steel with reinforced weld seams and corrosion-resistant transducer mounting—ensuring long-term dimensional stability under repeated thermal cycling and solvent exposure.
• Stable acoustic field distribution: Optimized tank geometry and transducer placement minimize standing wave formation and hot/cold spots, supporting uniform energy delivery across full-load volumes (2–40 L).
• Integrated safety architecture: Overtemperature cutoff, dry-run protection, and automatic shutdown upon lid opening comply with IEC 61000-6-3 EMC and IEC 61010-1 safety standards for laboratory equipment.

Sample Compatibility & Compliance

The HU Series accommodates a broad spectrum of pharmaceutical and botanical sample formats—including dried herb powders, granules, crushed tablets, filter paper extracts, and suspension-based reference standards. It supports aqueous, ethanol, methanol, and mixed-solvent systems commonly used in ChP Method 2201 (Ultrasonic Extraction for Assay Determination). All operational parameters are logged with timestamped metadata, enabling traceability per GLP and GMP Annex 11 requirements. While not FDA 21 CFR Part 11–certified out-of-the-box, the system’s deterministic control logic and non-volatile parameter storage allow integration into validated workflows when paired with compliant LIMS or ELN platforms. Documentation packages include factory calibration reports, material certifications (EN 10088-1), and conformity statements to GB/T 20142–2021 (Ultrasonic Equipment for Laboratory Use).

Software & Data Management

The HU Series features an embedded microcontroller-based interface with LCD display and tactile membrane keys—designed for glove-compatible operation in cleanroom and containment environments. Parameter sets can be saved as named protocols (e.g., “ChP_HuZhang_Extract_40kHz”) and recalled instantly. Optional RS-232 or USB-B output enables connection to external data loggers or lab automation systems. Audit trail functionality records all user-initiated changes—including power adjustments, temperature overrides, and timer resets—with operator ID tagging when integrated with network-authenticated controllers. Raw acoustic output stability is verified quarterly using calibrated hydrophone measurements (per ASTM E1002), and results are exportable as CSV for QA review.

Applications

• Pharmacopeial assay sample prep: Standardized extraction of active constituents from crude drugs prior to HPLC/UPLC analysis per ChP monographs.
• Stability-indicating method development: Evaluation of ultrasonic parameters on degradation kinetics of sensitive APIs under controlled thermal–acoustic stress.
• QC release testing: Batch-to-batch consistency verification for herbal extract concentrates and tinctures.
• Reference standard reconstitution: Rapid, particle-free dissolution of certified reference materials without vortex-induced foaming or oxidation.
• Pre-analytical processing in bioanalytical labs: Homogenization of tissue homogenates and plasma precipitates prior to LC-MS/MS quantification.

FAQ

Does the HU Series support validation documentation for GMP environments?
Yes—factory calibration certificates, material traceability sheets, and electrical safety test reports are provided. Full 3Q (IQ/OQ/PQ) protocol templates are available upon request for integration into site-specific validation master plans.
Is dual-frequency operation necessary for routine pharmacopeial work?
No—ChP and USP methods specify 40 kHz as the primary frequency for most herbal extractions. Dual-frequency capability is intended for method optimization studies, not routine compliance use.
Can the unit operate continuously for extended durations (e.g., 8+ hours)?
Yes—the cooling system and transducer thermal management architecture support uninterrupted operation within the rated temperature and duty-cycle limits specified in the technical manual.
What maintenance is required to sustain acoustic performance over time?
Quarterly verification of transducer impedance and bath degassing efficiency is recommended. Stainless steel tanks require only routine detergent cleaning; no ultrasonic bath solution additives are needed beyond standard laboratory-grade solvents.
Is remote monitoring or Ethernet connectivity available?
Not natively—but analog voltage outputs (0–10 V) for temperature and power status are accessible via terminal block, enabling integration with SCADA or building management systems.
