Savillex PFA Sample Bottle for Acid Distillation Systems

Overview

The Savillex PFA Sample Bottle is a critical consumable component engineered specifically for ultra-trace acid distillation systems—including sub-boiling (acid leaching) and hotplate-based distillation units such as the DST-1000. Constructed from high-purity perfluoroalkoxy (PFA) copolymer, this bottle serves as the primary sample containment vessel during high-temperature, low-volatility acid purification processes essential for elemental analysis by ICP-MS, ICP-OES, and GF-AAS. Its design adheres to the fundamental principles of inert sample handling: minimizing analyte adsorption, eliminating metallic contamination, and ensuring quantitative recovery of volatile and semi-volatile elements (e.g., As, Se, Sb, Hg, Tl) under aggressive thermal-acidic conditions. Unlike standard polypropylene or FEP containers, PFA offers superior melt-processability while retaining the chemical inertness and thermal stability of PTFE—enabling seamless integration into automated digestion workflows and closed-system distillation protocols.

Key Features

• Ultra-high purity PFA resin with certified trace-metal content ≤ 10 pg/g for Al, Cr, Fe, Ni, Cu, Zn, Cd, Pb, U, Th, and rare earth elements
• Thermal resistance up to 260 °C continuous use; compatible with reflux temperatures required for HNO₃/HF/HClO₄ distillations
• Zero extractables profile verified per USP and EPA Method 6020B; no detectable leaching of fluorinated oligomers or monomers under ASTM D543 immersion testing
• Optimized geometry for uniform heat distribution and condensate reflux control—reducing bumping and splashing during sub-boiling operation
• Chemically etched inner surface finish (Ra < 0.2 µm) to minimize surface area for analyte retention and facilitate complete rinse recovery
• Autoclavable and reusable after rigorous cleaning per Savillex SOP-ACID-07 (HNO₃/HF soak followed by 18.2 MΩ·cm DI water triple-rinse)

Sample Compatibility & Compliance

This PFA bottle is validated for use with hydrofluoric acid (HF), aqua regia, boiling nitric acid, perchloric acid (under controlled fume hood conditions), and mixed acid matrices commonly employed in geological, environmental, and nuclear materials preparation. It complies with ISO/IEC 17025:2017 requirements for reference material handling and meets GLP/GMP documentation standards for method validation in regulated laboratories. All lots undergo batch-specific certificate of analysis (CoA) verification for total metal impurities, non-volatile residue (NVR), and particle count (≥99.9% removal of ≥0.5 µm particles per ISO 14644-1 Class 5 cleanroom protocol). The material is USP Class VI certified and compliant with FDA 21 CFR 177.1550 for repeated food-contact and pharmaceutical excipient contact applications.

Software & Data Management

While the PFA bottle itself is a passive consumable, its traceability is fully integrated into Savillex’s digital asset management system. Each bottle carries a laser-etched alphanumeric lot ID linked to an encrypted cloud-accessible CoA portal containing full elemental screening data, thermal aging reports, and leachable profiles. Laboratories implementing LIMS (e.g., LabWare, Thermo Fisher SampleManager) can import these identifiers directly via CSV or API to maintain chain-of-custody records across digestion, distillation, and instrumental analysis stages—supporting audit readiness for ISO/IEC 17025, CLIA, or FDA 21 CFR Part 11 compliance.

Applications

• Ultra-trace metal purification prior to ICP-MS analysis of seawater, groundwater, and biological fluids
• Matrix separation in nuclear fuel cycle analytics (U/Pu isotopic ratio determination)
• Pre-concentration and decontamination of silicate rock digests for REE and HFSE quantification
• High-purity reagent generation for semiconductor wafer cleaning process validation
• Reference material certification workflows requiring ≤0.1 ng/g blank levels (e.g., NIST SRM 1640a, SLRS-6)

FAQ

Can this PFA bottle be used with hydrofluoric acid at elevated temperatures?
Yes—Savillex PFA bottles are rated for continuous exposure to 49% HF at temperatures up to 200 °C, validated per ASTM C711 and IEC 60674-2.

What is the maximum recommended reuse cycle before replacement?
Under strict adherence to Savillex cleaning SOP-ACID-07, bottles may be reused up to 20 cycles without measurable increase in procedural blanks (verified by daily method blanks).

Is there a documented shelf life for unopened bottles?
Unopened, sealed bottles retain specification integrity for 5 years when stored in ambient, dry, dark conditions per ISO 8573-1 Class 3 air quality guidelines.

Does this product support automated acid distillation platforms?
Yes—the standardized neck dimension (24/40 standard taper) ensures compatibility with Savillex DST-1000, Milestone ETHOS UP, and CEM Mars 6 distillation modules equipped with PFA-compatible condenser interfaces.
