Xianghu XH-200A+ Microwave-Assisted Solid-Liquid Synthesis and Extraction Workstation

Overview

The Xianghu XH-200A+ Microwave-Assisted Solid-Liquid Synthesis and Extraction Workstation is an integrated benchtop platform engineered for controlled, reproducible microwave energy delivery in both synthetic chemistry and analytical sample preparation workflows. It operates on the principle of dielectric heating—where polar molecules (e.g., water, alcohols, DMF, DMSO) and ionic species absorb 2450 MHz microwave radiation, converting electromagnetic energy into thermal energy at the molecular level. This enables rapid, volumetric, and selective heating—distinct from conventional conductive heating—thereby accelerating reaction kinetics, improving extraction efficiency, and enhancing product selectivity in heterogeneous systems. Designed for laboratories requiring flexibility across solid-phase catalysis, solvent-based extraction, hydrothermal synthesis, and green chemistry protocol development, the XH-200A+ supports closed-vessel and open-vessel configurations with real-time temperature monitoring and dynamic power modulation.

Key Features

• Stepless microwave power regulation (0–1000 W), enabling precise energy dosing for sensitive substrates or exothermic reactions.
• Dual-mode temperature control architecture: infrared non-contact sensing for liquid-phase monitoring and embedded thermocouple input for direct solid-phase or crucible-based temperature feedback (0–500 °C).
• High-strength austenitic stainless steel cavity (AISI 304 grade) with reinforced waveguide shielding and interlocked safety door, compliant with IEC 61000-6-3 (EMC) and IEC 61000-6-4 emission standards.
• Programmable reaction profiles with up to 10 user-defined stages—including ramp, hold, and cooldown segments—with automatic power adjustment based on real-time temperature deviation.
• Integrated magnetic stirring (optional external coupling) and pressure monitoring compatibility (when used with certified sealed vessels) for multi-parameter process control.
• CE-marked electrical safety design and UL-listed power supply module, supporting 220 VAC ±10%, 50/60 Hz operation.

Sample Compatibility & Compliance

The XH-200A+ accommodates a broad spectrum of sample formats: liquid–solid suspensions (e.g., plant matrix extraction), powdered catalysts in inert atmospheres, ceramic precursors in alumina crucibles, and polymerization mixtures in borosilicate glass or quartz reactors. Its temperature range (0–300 °C for liquids; 0–500 °C for solids) aligns with ASTM E2887 (standard guide for microwave-assisted sample preparation) and supports method development consistent with ISO 13877 (soil and sediment extraction) and USP <2021> (microwave-assisted digestion). The workstation does not include built-in pressure-rated vessels but is compatible with third-party CE-certified microwave-transparent reaction vessels rated to 20 bar and 300 °C. All operational parameters are logged with timestamp and user ID, satisfying GLP documentation requirements for audit-ready data traceability.

Software & Data Management

The system operates via an embedded industrial-grade HMI (Human-Machine Interface) with 7-inch capacitive touchscreen, supporting multilingual UI (English, Chinese, Spanish). Reaction logs—including power output, cavity temperature, elapsed time, and user-defined notes—are stored internally (≥10,000 cycle capacity) and exportable via USB 2.0 to CSV or XML. Optional PC-based Xianghu LabControl™ software (v3.2+) provides remote monitoring, statistical process analysis (SPC), and 21 CFR Part 11-compliant electronic signatures when deployed with Windows domain authentication and audit trail activation. Data encryption (AES-256) and role-based access control ensure compliance with institutional IT security policies.

Applications

• Rapid extraction of bioactive compounds (polyphenols, alkaloids, flavonoids) from botanical matrices using ethanol/water mixtures under subcritical conditions.
• Synthesis of metal–organic frameworks (MOFs) and perovskite nanocrystals via solvothermal routes with improved phase purity and reduced crystallization time.
• Accelerated leaching of heavy metals (Pb, Cd, As) from environmental solids (sludge, fly ash) for regulatory compliance testing (EPA Method 3052 adaptation).
• Catalytic C–C coupling reactions (Suzuki, Heck) under solvent-free or low-solvent conditions, minimizing waste generation and improving atom economy.
• Thermal degradation studies of polymers and composites where controlled microwave-specific heating effects (e.g., selective carbonization) are under investigation.

FAQ

Is the XH-200A+ suitable for high-pressure reactions?
No—the base configuration is designed for atmospheric or low-backpressure open/vented operation. For pressurized synthesis, users must integrate certified sealed vessels with independent pressure relief mechanisms and verify mechanical compatibility with the cavity dimensions.
Does it support external temperature probes for custom reactor setups?
Yes—via standard K-type thermocouple input (0–600 °C range) with cold-junction compensation, allowing integration with lab-built reactors or glovebox-mounted configurations.
Can multiple instruments be networked for centralized monitoring?
Yes—through optional Ethernet module (IEEE 802.3) and Modbus TCP protocol support, enabling SCADA-level integration in core facility environments.
What maintenance is required for long-term stability?
Annual calibration of IR sensor and thermocouple input against NIST-traceable references is recommended; cavity cleaning with non-abrasive stainless steel cleaner every 200 operating hours ensures optimal microwave coupling efficiency.
Is training and application support available internationally?
Yes—Xianghu provides English-language technical documentation, video SOP libraries, and remote application consultation (GMT+8 business hours), with authorized regional partners offering on-site installation verification and method transfer assistance.
