ETHOS A-Series 10-Position Microwave Digestion Vessels (TFM Body + PFA Cap + Safety Burst Ring)

Overview

The ETHOS A-Series 10-Position Microwave Digestion Vessels are precision-engineered consumables designed for full compatibility with Anton Paar’s ETHOS A microwave digestion platforms. These vessels operate on the principle of closed-vessel, high-pressure, high-temperature acid digestion—enabling rapid, complete mineralization of organic and inorganic matrices under controlled microwave irradiation. Each 100 mL vessel features a monolithic TFM (perfluoroalkoxy alkane) liner for exceptional chemical inertness against aggressive reagents (e.g., HNO₃, HF, HCl, H₂O₂, and aqua regia), coupled with a chemically resistant PFA (perfluoroalkoxy) cap and an integrated pressure-activated safety burst ring calibrated to release at ≥80 bar—ensuring consistent overpressure protection without compromising analytical integrity. Unlike incomplete kits that supply only liners or bodies, this product delivers a fully matched, functionally equivalent assembly validated for thermal cycling stability, dimensional repeatability, and leak-tight sealing across repeated digestions.

Key Features

• Complete 10-position vessel set: each unit includes TFM body, PFA cap, and factory-calibrated safety burst ring—no component substitution required.
• Material compatibility: TFM liner withstands temperatures up to 260 °C and pressures up to 80 bar; PFA cap maintains seal integrity and resists HF-induced degradation.
• Dimensional fidelity: manufactured to ISO 9001-certified tolerances; outer diameter, thread pitch, and burst ring seating geometry conform precisely to Anton Paar ETHOS A original equipment specifications.
• Trace-metal-clean manufacturing: produced in Class 10,000 cleanroom environments; all components undergo triple-rinse with ultrapure water (18.2 MΩ·cm) and certified low blank testing (≤10 pg/g for As, Cd, Cr, Pb, Hg).
• Rack integration: designed for seamless insertion into standard ETHOS A 10-position rotor assemblies—no adapter or alignment tooling needed.

Sample Compatibility & Compliance

These vessels support digestion protocols for a broad spectrum of sample types—including soils, sediments, biological tissues (plant/animal), foodstuffs, polymers, catalysts, and geological materials—under EPA Method 3051A, 3052, ISO 11466, ASTM D5762, and USP heavy metals testing requirements. The TFM/PFA construction ensures compliance with trace-element analysis workflows requiring sub-ppt detection limits (e.g., ICP-MS, ICP-OES). All materials meet EU REACH Annex XIV restrictions and are free of leachable borosilicate glass, silicone lubricants, or metal contaminants. Batch-specific certificates of conformance (CoC) and material test reports (MTRs) are provided upon request for GLP/GMP-regulated laboratories.

Software & Data Management

While these are passive consumables, their design enables full traceability within ETHOS A system software (Microwave Suite v5.2+). Each vessel set is supplied with serialized lot labels enabling audit-ready documentation in LIMS-integrated environments. The burst ring activation threshold is calibrated and verified per batch to ensure consistency with ETHOS A’s real-time pressure monitoring and automatic power modulation algorithms. For laboratories operating under FDA 21 CFR Part 11, the physical integrity and documented compatibility of these vessels support electronic record integrity during method validation and routine QC audits.

Applications

• Environmental testing: total recoverable metals in wastewater sludge (EPA 6010D), soil leachates (TCLP), and airborne particulates.
• Clinical & pharmaceutical: residual catalyst quantification in APIs, elemental impurity profiling per ICH Q3D guidelines.
• Food safety: Pb, Cd, As, and Hg determination in infant formula, seafood, and fortified cereals per AOAC 2013.06.
• Materials science: dissolution of rare-earth oxides, battery cathode materials (NMC, LFP), and ceramic composites prior to XRF or ICP analysis.
• Geochemical research: whole-rock digestion of silicates and carbonates using HF-HNO₃-HCl mixtures at 220 °C for Sr-Nd-Pb isotopic analysis.

FAQ

Are these vessels certified for use with Anton Paar ETHOS A systems?
Yes—each batch undergoes functional verification against OEM pressure cycling, torque sealing, and burst threshold tests. They are not “generic replacements” but engineered equivalents meeting ETHOS A mechanical and thermal interface specifications.
Do you supply documentation for regulatory submissions (e.g., FDA, ISO 17025)?
Yes—certificates of conformance, material declarations, and batch-specific blank data are available in English upon order confirmation.
Can these vessels be reused?
They are designed for multiple digestions (≥50 cycles) when cleaned per ASTM D5686 and inspected for liner deformation or cap thread wear; however, burst rings are single-use and must be replaced after each activation or every 20 cycles as preventive maintenance.
Is HF-compatible digestion supported?
Yes—the TFM liner and PFA cap provide full resistance to hydrofluoric acid up to 40% concentration at 220 °C, making them suitable for silicate and glass matrix dissolution.
What is the lead time for custom lot certification or LIMS integration support?
Standard CoCs ship with goods; extended documentation (e.g., GMP-style batch records, IQ/OQ templates) requires 5 business days and is included at no additional cost for orders ≥50 sets.
