PFA Sample Vial, 15 mL Semi-Transparent, NJ-PFA-SG-015

Overview

The Binzhenghong NJ-PFA-SG-015 is a high-purity, semi-transparent 15 mL sample vial fabricated from perfluoroalkoxy alkane (PFA), a fluoropolymer renowned for its exceptional chemical inertness, thermal stability, and ultra-low extractables profile. Engineered specifically for demanding analytical workflows—including trace-level elemental analysis (ICP-MS, ICP-OES), high-sensitivity chromatography (HPLC, UHPLC, GC), and radiochemical or pharmaceutical stability studies—the vial leverages PFA’s intrinsic resistance to strong acids (e.g., aqua regia, HF up to 40%), bases, oxidizers, and organic solvents across a broad temperature range (–200 °C to +260 °C). Unlike glass or polypropylene alternatives, PFA eliminates metal ion leaching, silicate interference, and adsorptive loss of analytes—critical for sub-part-per-trillion quantitation and long-term storage of volatile or reactive species. Its semi-transparency enables rapid visual verification of sample volume and homogeneity without compromising UV/Vis spectral integrity below 200 nm.

Key Features

• Material purity: ASTM D4894-compliant PFA resin with ≤10 ppt total metal impurities (measured by ICP-MS after acid digestion)
• Dimensional consistency: Tight tolerance control (±0.15 mm diameter, ±0.2 mm height) ensures reliable autosampler compatibility with Agilent, Thermo Fisher, Shimadzu, and Waters platforms
• Sealing integrity: Designed for use with standard 13-425 or 15-425 screw-thread caps; compatible with PTFE/silicone septa for hermetic, low-permeability closure
• Thermal resilience: Withstands repeated autoclaving (121 °C, 20 min), freeze-thaw cycling (–80 °C to 25 °C), and direct heating on hot plates or in oven-dryers without deformation or outgassing
• Surface properties: Non-stick, low-surface-energy interior minimizes analyte adhesion—validated for recovery rates ≥98.5% of arsenic, mercury, and platinum group elements in 1% HNO₃ matrix

Sample Compatibility & Compliance

The NJ-PFA-SG-015 vial is validated for direct contact with aqueous standards, organic extracts (acetonitrile, methanol, chloroform), hydrofluoric acid solutions (≤40%), and alkaline digestates (e.g., NaOH/KOH fusion melts). It complies with ISO 17025 requirements for certified reference material handling and meets USP specifications for plastic containers used in pharmaceutical analysis. Batch-specific Certificate of Analysis (CoA) includes FTIR identity confirmation, residual catalyst screening (by GC-MS), and extractables testing per USP using simulated extraction solvents (water, 50% ethanol/water, n-hexane). Each lot undergoes particulate inspection under Class 100 cleanroom conditions and is traceable via laser-etched batch ID.

Software & Data Management

While the vial itself is a passive consumable, it integrates seamlessly into LIMS and ELN ecosystems through standardized barcode labeling (optional 1D/2D GS1-compliant symbology). Binzhenghong provides digital CoA delivery via secure portal with audit-trail-enabled download history, supporting FDA 21 CFR Part 11 compliance when paired with validated electronic signature workflows. Vial lot data—including raw material certification, sterilization logs (if applicable), and QC test reports—is retained for ≥10 years and available upon request for GLP/GMP audits.

Applications

• Ultra-trace metal analysis in environmental water, soil digests, and biological fluids (EPA Method 200.8, ISO 17294-2)
• Stability-indicating assays for biologics and small-molecule APIs exposed to acidic or oxidative stress conditions
• Radioisotope handling (e.g., ⁹⁹mTc, ¹⁸F-labeled tracers) due to negligible gamma-ray attenuation and no neutron activation risk
• Calibration standard preparation and long-term stock solution storage (>12 months at 4 °C without measurable degradation)
• On-site field sampling where breakage resistance and chemical robustness surpass glass alternatives

FAQ

Is this vial suitable for hydrofluoric acid (HF) applications?

Yes—PFA exhibits the highest resistance among commercially available polymers to HF, including concentrations up to 40% at ambient temperature. Continuous exposure above 60 °C requires validation for specific application conditions.
Can these vials be sterilized by autoclaving?

Yes—they are rated for repeated autoclaving at 121 °C for 20 minutes without dimensional change or leachable increase. Sterilization does not affect extractables profile or mechanical integrity.
Do you provide pre-cleaned, certified low-metal vials?

Yes—Binzhenghong offers optional pre-rinsing with ultrapure 18.2 MΩ·cm water and HNO₃ followed by Class 100 cleanroom packaging. Certificates confirm ≤0.1 pg/mL background for Al, Cr, Fe, Ni, and Zn.
What cap configurations are recommended?

Standard 13-425 or 15-425 thread sizes accommodate PTFE-faced silicone septa (thickness: 3 mm) or conductive PTFE/silicone blends for static-sensitive applications. Caps must be torqued to 12–15 in·lb to ensure leak-tight sealing without thread damage.
How is batch traceability maintained?

Each production lot carries a unique alphanumeric identifier laser-etched on the vial base, linked to full QC documentation, raw material lot numbers, and environmental monitoring records archived per ISO 9001:2015 clause 8.5.2.
