PFA Headspace Vial (50 mL) with Screw Cap and PTFE-Silicone Septum – NJ-PFA-JYP by Binzhenghong

Overview

The Binzhenghong NJ-PFA-JYP is a high-purity, chemically inert 50 mL headspace vial engineered for trace-level volatile organic compound (VOC) analysis in gas chromatography (GC), GC–mass spectrometry (GC–MS), and headspace sampling applications. Constructed entirely from premium imported perfluoroalkoxy alkane (PFA) resin—distinct from standard PTFE or FEP—the vial exhibits superior resistance to aggressive solvents (e.g., concentrated HF, aqua regia, hot nitric acid), ultra-low extractables (<0.1 ng/g), and negligible background interference in sensitive detection regimes. Its seamless, blow-molded body eliminates weld lines that could trap analytes or generate leachables. The calibrated volume scale (±0.5 mL tolerance at 20 °C) enables precise liquid-phase equilibration in quantitative static headspace methods per ASTM D6866 and ISO 14855-2 protocols.

Key Features

• Material integrity: Fully PFA construction (ASTM D4894-compliant fluoropolymer) ensures non-reactivity with halogenated solvents, strong oxidizers, and high-pH bases—critical for EPA Method 502.2, 8260D, and USP residual solvent testing.
• Dimensional precision: 50 mL nominal capacity with molded graduation marks (0–50 mL, 5 mL increments); outer diameter 27.8 mm, height 68.5 mm—compatible with standard autosampler trays (Agilent 7697A, Thermo TriPlus RSH, Shimadzu AOC-6000).
• Sealing system: Aluminum screw cap with integrated 3.0 mm thick PTFE/silicone septum (double-layer, 13 mm diameter); certified for ≥100 punctures without leakage or coring (per USP septum integrity testing).
• Manufacturing control: Produced in an ISO 9001-certified cleanroom (Class 10,000); each batch undergoes FTIR verification of polymer identity and ICP-MS screening for metallic contaminants (Na, K, Fe, Cr, Ni ≤ 5 ppt).
• Traceability: Individual vials laser-engraved with batch ID and manufacturing date; full CoA provided including residual moisture (0.5 µm particles), and outgassing profile (TGA weight loss <0.02% at 200 °C).

Sample Compatibility & Compliance

The NJ-PFA-JYP vial is validated for use with aqueous, alcoholic, acidic, and highly polar matrices—including pharmaceutical formulations, environmental water extracts, polymer leachates, and battery electrolyte samples. It meets the material compatibility requirements of ICH Q5C (stability-indicating containers), FDA 21 CFR Part 11 (when used within validated LIMS/GC data systems), and GLP Annex 7 (sample integrity documentation). Its low surface energy (contact angle >110°) minimizes adsorption of polar VOCs such as formaldehyde, acetaldehyde, and ethylene oxide—reducing memory effects across sequential injections. Not recommended for long-term storage of strongly alkaline solutions (>pH 13) above 60 °C due to gradual PFA chain scission.

Software & Data Management

While the vial itself is a passive consumable, its integration into regulated workflows requires traceable documentation. Binzhenghong provides digital batch records accessible via QR code on packaging—linking to PDF CoAs, sterilization logs (if gamma-irradiated option selected), and raw ICP-MS spectra. When paired with compliant GC data systems (e.g., OpenLab CDS, Chromeleon), the vial’s batch ID can be embedded directly into sample audit trails, satisfying FDA 21 CFR Part 11 electronic record requirements for signature, time-stamping, and change control. Optional serialization supports ASME BPE-2023 traceability standards for biopharma process validation.

Applications

• Residual solvent quantification in APIs and excipients (USP , Ph. Eur. 2.4.24)
• VOC profiling in drinking water per EPA Method 524.4 and ISO 22067-1
• Off-gas analysis from lithium-ion battery electrolytes (LiPF₆/EC/DMC)
• Headspace monitoring of degradation products in sterile medical device packaging (ISO 10993-12)
• High-sensitivity analysis of sulfur compounds (e.g., mercaptans) in petrochemical streams

FAQ

Is this vial suitable for automated headspace samplers?
Yes—the standardized dimensions and torque-spec cap ensure reliable sealing and tray alignment with Agilent, Thermo, and Shimadzu autosamplers.
Can it be autoclaved?
No. PFA softens above 260 °C; repeated steam sterilization causes dimensional creep. For sterile applications, gamma irradiation (25 kGy) is available as a custom option.
What is the shelf life under ambient storage?
36 months from manufacture date when stored sealed in original packaging, away from UV light and ozone sources.
Do you provide certificates of conformance for GMP audits?
Yes—each box includes a signed CoC referencing ISO 9001:2015, plus optional 3rd-party test reports from SGS or TÜV upon request.
Are custom labeling or barcoding services available?
Yes—custom laser etching (batch ID, expiry, client logo) and GS1-128 barcode application are supported for enterprise procurement integration.
