Overview
The ETHOS A-Series 10-Position Microwave Digestion Vessel Set (Model A-Type – 100 mL) is a rigorously engineered consumable system designed for high-throughput, trace-metal-grade sample preparation in accredited environmental, geochemical, food safety, and clinical laboratories. Built upon the established ETHOS platform architecture, this vessel set implements controlled microwave-assisted acid digestion via closed-vessel pressurized thermolysis—leveraging dielectric heating of HNO₃, HCl, HF, and H₂O₂ mixtures under inert atmosphere conditions. Each 100 mL vessel operates within a validated pressure envelope of ≤80 bar and temperature range up to 300 °C, enabling complete mineralization of refractory matrices including silicates, alloys, biological tissues, and polymer composites while minimizing elemental volatilization losses (e.g., As, Hg, Se). The system integrates seamlessly with ETHOS A-series microwave digestion workstations (e.g., Milestone ETHOS UP, ETHOS EX), supporting method-driven automation and full audit trail generation per GLP/GMP requirements.
Key Features
- TFM-1600 fluoropolymer vessel bodies: Chemically inert, low extractables (<0.1 ng/mL metal background), resistant to aqua regia and hydrofluoric acid at elevated temperatures
- PFA screw-thread lids with dual-seal geometry: Ensures leak-tight containment during rapid pressure ramping; integrated venting channel maintains safe overpressure release path
- Color-coded safety burst disc rings (red indicator): Mechanically calibrated rupture threshold at 100 bar ±5%, providing deterministic overpressure protection independent of electronic controls
- 10-position precision-machined rack: CNC-fabricated polyetherimide (PEI) carrier with ISO-standard spacing (48 mm center-to-center), compatible with robotic arm handling and thermal uniformity validation protocols
- Trace-metal-clean manufacturing: Vessels assembled in Class 1000 cleanroom environment; certified per ISO 14644-1; individual lot traceability with CoA (Certificate of Analysis) including ICP-MS blank testing data
Sample Compatibility & Compliance
This vessel set accommodates solid, semi-solid, and liquid samples across regulatory and research applications—including soil (EPA 3050B), sediments (ISO 11885), plant tissue (AOAC 999.10), pharmaceutical excipients (USP ), and wastewater sludge (EN 13656). All materials comply with FDA 21 CFR §177.1550 (fluoropolymers for food contact) and EU Regulation (EC) No 1935/2004. Vessel performance meets ASTM D5686 (microwave digestion system validation) and supports method transfer between ETHOS platforms without recalibration. Each batch undergoes hydrostatic pressure cycling (3× rated max pressure) and helium leak testing (≤1×10⁻⁹ mbar·L/s sensitivity).
Software & Data Management
While the vessels themselves are passive hardware components, their use is fully integrated into ETHOS workstation software (v4.2+), enabling digital logbook entries, vessel lifecycle tracking (usage count, thermal cycles), and automated QC flagging based on pressure/temperature deviation thresholds. Audit trails conform to 21 CFR Part 11 requirements—including electronic signatures, immutable timestamping, and role-based access control—ensuring full traceability from sample loading to final digestate analysis.
Applications
- Multi-element analysis (ICP-OES/ICP-MS) of geological samples requiring complete silicate dissolution
- Heavy metal screening in consumer products (CPSIA, RoHS 2 Directive)
- Nutrient and contaminant profiling in agricultural commodities (Codex Alimentarius standards)
- Leachate characterization in waste management compliance testing (TCLP, SPLP)
- Reference material certification (NIST SRM, BCR CRM) preparation under ISO/IEC 17025
FAQ
Are these vessels compatible with non-Milestone microwave systems?
No—mechanical, thermal, and communication interfaces are proprietary to the ETHOS A-series platform. Cross-platform use voids warranty and compromises safety validation.
What is the maximum recommended number of digestion cycles per vessel?
Based on accelerated life testing per ASTM E2913, TFM bodies maintain dimensional stability and seal integrity for ≥200 cycles when operated within specified pressure/temperature limits and cleaned per SOP NJ-ZH-CLE-01.
Do you provide certificates of conformance for individual lots?
Yes—each shipment includes a Certificate of Conformance (CoC) and Certificate of Analysis (CoA) with ICP-MS blank data, pressure test records, and material traceability (TFM resin lot #, PFA extrusion batch #).
Is HF acid digestion supported?
Yes—TFM-1600 exhibits superior resistance to HF vs. standard PTFE; however, post-digestion neutralization and fluoride-specific cleaning protocols must be followed to prevent long-term polymer degradation.
Can the 10-position rack be autoclaved?
No—PEI rack material is not autoclave-rated; dry heat sterilization at 120 °C for 30 min is permitted only if no residual acid residue is present.
