Overview
The Binzhenghong PTFE Rectangular Storage Tray is a precision-engineered, custom-fabricated laboratory containment solution designed for long-term storage, handling, and processing of chemically aggressive or ultra-pure samples. Constructed entirely from virgin polytetrafluoroethylene (PTFE), this tray leverages the material’s intrinsic chemical inertness, non-stick surface, low coefficient of friction, and exceptional thermal stability (–200 °C to +260 °C continuous use). Unlike molded or machined alternatives with potential voids or filler content, this unit is fabricated from solid 5 mm-thick PTFE sheet—ensuring structural integrity, dimensional stability under thermal cycling, and zero leachable contaminants. Its rectangular geometry (350 mm × 250 mm × 100 mm internal depth) supports standardized sample rack integration, solvent immersion protocols, and controlled evaporation workflows in analytical, pharmaceutical, and materials R&D environments.
Key Features
- Monolithic PTFE Construction: Fabricated from solid, unfilled, ASTM D4894-compliant virgin PTFE sheet—no binders, fillers, or laminates—to guarantee consistent corrosion resistance across all surfaces and edges.
- Dimensional Precision & Rigidity: CNC-machined with ±0.2 mm tolerance on critical dimensions; 5 mm wall thickness provides mechanical robustness against deformation during repeated handling or vacuum desiccation.
- Chemical Resistance Profile: Immune to virtually all strong acids (including aqua regia and fuming sulfuric acid), alkalis, halogens, organic solvents (e.g., THF, DMF, chloroform), and oxidizing agents—validated per ASTM D543 and ISO 17892-3 exposure protocols.
- Ultra-Low Extractables: Compliant with USP and cytotoxicity and extractables testing criteria; suitable for ICH Q5C bioburden-sensitive applications and high-purity semiconductor wafer cleaning stages.
- Thermal & Electrical Stability: Maintains dimensional and dielectric properties across –200 °C to +260 °C; volume resistivity >1018 Ω·cm ensures compatibility with electrochemical cell assemblies and static-sensitive cleanroom operations.
Sample Compatibility & Compliance
This tray accommodates diverse sample formats including glass vials, quartz crucibles, silicon wafers, polymer films, and metal coupons—without risk of catalytic degradation or ion leaching. Its smooth, non-porous surface prevents adsorption of trace organics or metals, supporting EPA Method 502.2 (halogenated hydrocarbons) and ASTM E2912 (trace metal analysis) workflows. The design conforms to GLP documentation requirements for equipment qualification (IQ/OQ/PQ), and its material certification includes full lot traceability, fluorine content verification (>76% by mass), and ash residue ≤0.001% (per ASTM D4895). Optional third-party validation reports (e.g., ISO/IEC 17025-accredited testing) are available upon request for regulated pharmaceutical or aerospace QA/QC labs.
Software & Data Management
As a passive, non-electronic containment device, this PTFE tray does not incorporate embedded sensors or digital interfaces. However, it is fully compatible with LIMS-integrated lab workflows: physical labeling (laser-etched ID codes or autoclavable RFID tags) enables unambiguous sample tracking. Its standardized footprint aligns with robotic liquid handlers (e.g., Tecan Freedom EVO, Hamilton STAR) and automated storage/retrieval systems (ASRS) used in high-throughput screening facilities. All fabrication records—including raw material certificates of conformance (CoC), dimensional inspection reports, and surface roughness (Ra < 0.8 µm) data—are archived digitally and provided with shipment to support audit readiness under FDA 21 CFR Part 11 and EU Annex 11 requirements.
Applications
- Long-term storage of HF-based etchants in microelectronics fabrication cleanrooms
- Acid digestion vessels for ICP-MS sample preparation (EPA 3052)
- Controlled crystallization platforms for API polymorph screening
- Electrode soaking trays in battery R&D (Li-ion, solid-state electrolyte compatibility)
- Reagent reservoirs for automated titration and potentiometric analysis
- Passivation baths for stainless steel medical device components (ASTM A967)
FAQ
Is this tray suitable for use with hydrofluoric acid (HF)?
Yes—virgin PTFE exhibits no measurable degradation in concentrated HF at room temperature for extended durations (≥12 months), as confirmed by weight loss testing per ASTM D543.
Can the tray be sterilized via autoclaving?
No—autoclaving exceeds PTFE’s upper service limit (121 °C saturated steam = ~200 kPa, exceeding safe thermal stress thresholds). Alternative sterilization methods include dry heat (180 °C for 2 hours) or gamma irradiation (≤50 kGy).
Do you provide dimensional drawings and material certifications?
Yes—each shipment includes a certified drawing (PDF + STEP), CoC with lot-specific fluorine assay, and surface finish report. Traceable calibration artifacts are supplied for metrology lab acceptance.
What is the lead time for custom configurations?
Standard lead time is 10–12 working days from drawing approval. Expedited fabrication (7 days) is available with priority scheduling and engineering review.
