Overview
The Hanon MASTER Ultra-High-Throughput Closed-Vessel Microwave Digestion & Extraction Workstation is engineered for precision, safety, and scalability in modern analytical laboratories. It operates on the principle of controlled microwave energy absorption by polar molecules (e.g., HNO₃, HCl, HF) within sealed reaction vessels, enabling rapid, uniform thermal decomposition of complex matrices under elevated temperature and pressure. Unlike conventional open-vessel or low-throughput systems, the MASTER platform integrates advanced cavity engineering, real-time multi-point pressure/temperature monitoring, and mechanically robust rotor architecture to support reproducible digestion of refractory samples—including geological silicates, high-alloy metals, ceramics, and polymeric materials—under sustained conditions up to 310 °C and 2200 psi (15.2 MPa). Its design directly addresses critical limitations observed in legacy high-throughput instruments: inconsistent field distribution, mechanical fatigue of polymer-based pressure-release mechanisms, cross-contamination from pneumatic pressure transduction, and thermal gradients across large-capacity rotors.
Key Features
- Industrial-grade 65 L stainless steel (316L) cavity with dual-layer PFA coating for long-term resistance to aggressive acids (HF, aqua regia) and corrosion.
- Dual magnetron microwave source (2450 MHz, 2200 W max output) with non-pulsed, frequency-variable power control ensuring stable energy delivery and minimal hot-spot formation.
- Uni-Turn continuous unidirectional rotation system eliminates cable twisting, reduces motor wear, and enables uniform microwave exposure across all vessels—critical for 40–100 vessel configurations.
- PE-Tec piezoelectric pressure sensing technology integrated directly into the rotor base or top plate; 120–140 mm signal path eliminates gas-tube leakage, cross-contamination, and mechanical failure—supporting full-range pressure control from 0 to 15 MPa (±0.01 MPa accuracy).
- XtraFiber composite outer vessels—carbon-fiber-reinforced polymer fully encapsulated in PFA—rated to 10,000 psi burst pressure and 500–600 °C thermal stability; certified for repeated use without degradation.
- Safety Bolt quantitative pressure-release mechanism: metal-actuated, non-sacrificial, directional venting only upon exceeding pre-set thresholds—no consumable membranes, no loss of seal integrity during normal operation.
- Rapid active cooling: high-turbulence axial fan system cools from 200 °C to 60 °C in ≤15 minutes, minimizing downtime between batches.
- Auto-Pop six-layer passive safety door with electromechanical interlock verification and force-dissipating lateral displacement—compliant with IEC 61000-4-3 and EN 61000-6-3 EMI/EMC standards.
Sample Compatibility & Compliance
The MASTER accommodates a modular suite of rotor configurations—16-vessel independent-frame, 14-vessel 200 mL high-mass, 18-vessel ultra-high-pressure (up to 260 °C / 6 MPa), 40-vessel mid-pressure, and industry-leading 100-vessel throughput platforms—each validated for trace-metal analysis in accordance with US-EPA Methods 3050B, 3051A, 3052; ASTM D5191, D7348; and ISO 11885. All TFM inner vessels meet FDA CFR 21 Part 177 requirements for food-contact compliance. The system’s pressure and temperature control architecture satisfies GLP/GMP audit-trail requirements when paired with optional Ethernet connectivity and time-stamped data logging. Full compatibility with ICP-MS, ICP-OES, and AAS instrumentation is ensured via low-blank digestion performance (<0.5 pg/g background for As, Cd, Pb, Hg in certified reference materials).
Software & Data Management
The MASTER features an embedded 7-inch HD LED touchscreen interface supporting multi-page real-time visualization of temperature/pressure curves, power modulation profiles, and stepwise ramp-hold protocols. Over 1,000 pre-validated digestion methods—including matrices for soils, ores, biological tissues, polymers, and environmental sludges—are stored onboard and searchable by sample type, acid system, or regulatory standard (US-EPA, ASTM, ISO). User-defined methods can be saved with metadata tagging, version control, and operator ID authentication. Optional Ethernet, RS-232, and USB interfaces enable integration with LIMS environments and remote supervision via tablet or smartphone using encrypted HTTP(S) streaming. Audit logs record all parameter changes, run completions, and safety events with ISO/IEC 17025-compliant timestamping and user attribution.
Applications
The MASTER is deployed across geochemical laboratories (e.g., National Geological Experimentation Testing Center), environmental monitoring agencies, food safety testing facilities, metallurgical R&D centers, and pharmaceutical QC labs. It routinely processes challenging samples such as basaltic rock powders (requiring ≥260 °C/6 MPa), stainless steel alloys (Cr/Ni/Mo-rich phases), ceramic composites, coal ash, and activated carbon filters—achieving complete dissolution without elemental volatilization or incomplete oxidation. Its 200 mL LV-200 rotor supports high-mass digestion (1–2 g) for low-concentration analytes in plant tissue or sediment; the 100-vessel HP-100 rotor enables statistically robust batch processing for regulatory compliance screening in food surveillance programs. Optional magnetic stirring (on 14- and 18-vessel rotors) enhances homogeneity for heterogeneous suspensions.
FAQ
What safety certifications does the MASTER workstation meet?
The system complies with IEC 61010-1 (Safety Requirements for Electrical Equipment), EN 61326-1 (EMC for Laboratory Equipment), and incorporates design elements aligned with ISO/IEC 17025 clause 6.4.1 for equipment validation.
Can the MASTER be used for microwave-assisted extraction (MAE), not just digestion?
Yes—the platform supports closed-vessel MAE protocols using organic solvents (e.g., methanol, acetone) at temperatures up to 200 °C and pressures ≤10 MPa, with method templates available for PAHs, PCBs, and pesticide residue extraction.
Is remote monitoring supported out-of-the-box?
Wireless visual monitoring is an optional module; however, basic remote parameter viewing and run initiation are enabled via Ethernet or USB host connection using Hanon’s proprietary LabLink software.
How often must Safety Bolt components be replaced?
Under normal operating conditions (≤15 MPa), Safety Bolt assemblies require no periodic replacement; they are designed for indefinite service life unless subjected to catastrophic overpressure events (>2200 psi) triggering irreversible actuation.
Does the system provide full traceability for regulatory audits?
When configured with network logging and user authentication, the MASTER generates tamper-evident electronic records—including method parameters, sensor readings, timestamps, and operator IDs—fully compatible with FDA 21 CFR Part 11 requirements for electronic signatures and audit trails.
