Overview
The Binzhenghong JYB PFA Sample Cup is a high-purity, custom-engineered fluoropolymer digestion vessel designed for rigorous analytical sample preparation workflows. Constructed entirely from perfluoroalkoxy alkane (PFA), this transparent cup offers exceptional chemical inertness, thermal stability (–200 °C to +260 °C), and optical clarity—enabling real-time visual monitoring during microwave-assisted acid digestion, hotplate digestion, or low-temperature solvent extraction. Unlike standard polypropylene or glassware, PFA exhibits near-zero extractables and negligible metal leaching, making it indispensable for trace-metal analysis (e.g., ICP-MS, ICP-OES), environmental testing (EPA Methods 3050B, 3051A, 3052), and pharmaceutical residual solvent determination (ICH Q3C). Its seamless, molded geometry eliminates crevices that could retain analytes or compromise cleaning validation—critical for laboratories operating under GLP or ISO/IEC 17025-accredited protocols.
Key Features
- Material: ASTM D4895-compliant PFA resin with ≥99.999% purity; certified heavy-metal-free (Cd, Pb, As, Hg < 0.1 ppb by ICP-MS)
- Optical Transparency: >92% transmittance across 200–2500 nm UV-Vis-NIR range—supports in-situ reaction observation and colorimetric endpoint detection
- Thermal Performance: Withstands rapid temperature cycling (–80 °C to +260 °C) without crazing or dimensional drift; compatible with microwave digestion rotors (CEM MARS 6, Anton Paar Multiwave PRO)
- Surface Finish: Electropolished inner wall (Ra 99.5% for Cr, Ni, Zn spikes at 1 ng/mL level)
- Customization: Available in volumes from 5 mL to 100 mL; optional features include graduated markings (±0.5% accuracy), threaded caps with PFA septa, and laser-etched lot traceability
Sample Compatibility & Compliance
The JYB PFA Cup demonstrates full compatibility with aggressive reagents including concentrated HF (up to 49%), aqua regia, HNO₃/H₂O₂ mixtures, and organic solvents (acetone, acetonitrile, THF). It meets USP Class VI biocompatibility requirements and complies with ISO 10993-5 (cytotoxicity) for use in regulated life science applications. Each production batch undergoes rigorous quality control per ASTM E2912—testing for halogen content (Cl⁻, F⁻ < 5 ppb), particulate count (110°). Certificates of Analysis (CoA) and Material Traceability Reports are supplied with every order, supporting FDA 21 CFR Part 11–aligned audit trails.
Software & Data Management
While the JYB cup is a passive component, its design integrates seamlessly into digital lab ecosystems. Barcoded or QR-coded variants (optional) enable direct association with LIMS entries (e.g., Thermo Fisher SampleManager, LabVantage) for automated sample history tracking. When used with smart digestion systems (e.g., Berghof Speedwave, Milestone ETHOS UP), cup-specific thermal profiles and pressure logs can be mapped to individual vessels via RFID-enabled rotor identification—ensuring full chain-of-custody compliance for ISO/IEC 17025 Clause 7.7 and GLP Principle 5. Raw CoA data is exportable in CSV and PDF/A-1b formats for long-term archival.
Applications
- Trace elemental analysis of geological, biological, and food matrices prior to ICP-MS quantification
- Stabilization and storage of hygroscopic or oxidation-sensitive standards (e.g., Fe²⁺, Cr³⁺ solutions)
- Inert containment for calibration standard dilution series to prevent wall adsorption artifacts
- Low-background blank preparation in cleanroom environments (ISO Class 5 or better)
- Method development for EPA SW-846 Method 6010D and ISO 17294-2:2016
FAQ
Can the JYB PFA cup be reused? Why or why not?
Yes—provided strict cleaning protocols are followed (e.g., 3× rinse with 18.2 MΩ·cm DI water, followed by 10% HNO₃ soak and final ultrasonic bath). Reuse is validated up to 20 cycles for non-HF applications; HF exposure mandates single-use due to potential surface fluorination.
Is the cup suitable for use in pressurized microwave digestion systems?
Yes—certified for static pressures up to 100 bar and burst pressures exceeding 250 bar when used within manufacturer-specified rotor configurations and temperature limits.
How does PFA compare to other fluoropolymers like FEP or ETFE in digestion applications?
PFA offers superior melt-processability, higher continuous-use temperature (+260 °C vs. +200 °C for FEP), and lower gas permeability than ETFE—making it optimal for volatile acid containment and long-duration reflux.
Do you provide lot-specific certificates of conformance?
Yes—each shipment includes a CoA with batch number, manufacturing date, raw material certificate (per ASTM D4895), and test results for metals, organics, and particulates.
