Overview
PFA sample vials manufactured by Binzhenghong are engineered for ultra-high-purity applications in semiconductor fabrication, analytical chemistry, environmental testing, and pharmaceutical quality control. Constructed from virgin perfluoroalkoxy alkane (PFA), these vials exhibit exceptional chemical inertness across the full pH spectrum (0–14), resistance to aggressive solvents (including hydrofluoric acid, aqua regia, and hot concentrated bases), and negligible leachable content—critical for trace-element analysis (e.g., ICP-MS, ICP-OES) and low-background radiochemical assays. Unlike glass or standard polyethylene containers, PFA offers near-zero metal ion extraction, minimal organic volatiles, and thermal stability up to 260 °C, enabling use in high-temperature digestion, solvent storage, and cleanroom-compatible sampling workflows.
Key Features
- Material Integrity: Made exclusively from ASTM D4894-compliant PFA resin—free of fillers, plasticizers, or recycled content—to ensure consistent purity and dimensional stability.
- Low Extractables Profile: Validated per USP and ISO 10993-12 protocols; total organic carbon (TOC) release < 0.5 µg/L after 72-h aqueous extraction at 60 °C.
- Optical Clarity & Dimensional Precision: Transparent, bubble-free walls with tight tolerance on wall thickness (±0.05 mm) and neck geometry (GL32/GL45 standardized threads per DIN 12451).
- Thermal & Mechanical Robustness: Withstands repeated autoclaving (121 °C, 20 min), freeze-thaw cycling (−40 °C to +150 °C), and mechanical stress without crazing or delamination.
- Cleanroom-Compatible Packaging: Supplied in ISO Class 5 (Class 100) laminar flow environments; double-bagged in static-dissipative polyethylene with certificate of conformance (CoC) and lot-specific test data.
Sample Compatibility & Compliance
These vials are validated for direct contact with high-purity acids (HF, HNO₃, HCl, H₂SO₄), bases (NaOH, KOH), organic solvents (acetone, acetonitrile, THF), and ultrapure water (UPW). They meet critical requirements for semiconductor process chemicals (SEMI F57, SEMI F63), EPA Method 200.8/6020B sample preservation, and ISO/IEC 17025-accredited laboratories. The absence of silicates, borosilicates, or heavy-metal catalysts eliminates interference in elemental speciation studies and prevents catalytic degradation of sensitive analytes (e.g., perfluorinated compounds, organometallics).
Software & Data Management
While PFA vials are passive consumables, Binzhenghong provides digital traceability support: each production lot includes a QR-coded CoC with batch-specific test reports (ICP-MS residual metal screening, FTIR identity verification, and particulate count per ISO 14644-1 Class 5). Integration with LIMS platforms is supported via CSV export of lot metadata, including sterilization validation records (if applicable) and extractables summary tables compliant with FDA 21 CFR Part 11 audit-trail requirements for GMP-regulated environments.
Applications
- Semiconductor wafer cleaning and etchant storage (HF-based chemistries, SC1/SC2 solutions)
- Trace-metal analysis in environmental water, soil digests, and biological matrices
- Stabilized storage of calibration standards (ppq–ppt level) and reference materials
- Long-term archiving of volatile organic compounds (VOCs) and halogenated solvents
- On-site field sampling for EPA, ISO, and ASTM methods requiring non-reactive containment
- Preparation and storage of reagents for photolithography and thin-film deposition processes
FAQ
Are these vials suitable for hydrofluoric acid (HF) storage?
Yes. PFA exhibits the highest resistance among fluoropolymers to HF corrosion—even at elevated concentrations and temperatures—making it the material of choice for semiconductor wet benches.
Do you provide certificates of analysis (CoA) with each shipment?
Yes. Every lot includes a CoA detailing ICP-MS screening for ≥32 elements (Al, As, Cd, Cr, Cu, Fe, Ni, Pb, Zn, etc.), FTIR spectral match, and visual inspection against ISO 11137 sterility assurance levels (if gamma-irradiated option selected).
Can these vials be autoclaved repeatedly without performance loss?
Yes. PFA maintains structural integrity and extractables profile through ≥50 autoclave cycles (121 °C, 15 psi, 20 min), verified per ASTM F1638 accelerated aging tests.
What neck finishes are available, and are caps included?
Standard options are GL32 (25 mm thread) and GL45 (45 mm thread); screw caps with PFA-faced silicone or Viton® liners are available separately to maintain sealing integrity under vacuum or inert gas headspace.
Is custom labeling or serialization available for LIMS integration?
Yes. Binzhenghong supports laser-etched alphanumeric codes, 2D DataMatrix barcodes, and custom label printing (non-adhesive, solvent-resistant ink) compatible with automated sample tracking systems.
