PFA Precision Pipette Tips for Eppendorf, Thermo Fisher, and DLAB Pipettors

Overview

PFA Precision Pipette Tips are high-purity, chemically inert consumables engineered for demanding liquid handling applications in analytical chemistry, pharmaceutical QC, environmental testing, and trace metal analysis. Constructed from perfluoroalkoxy alkane (PFA), these tips exhibit exceptional resistance to aggressive solvents—including concentrated acids (e.g., HF, HNO₃, aqua regia), strong bases, halogenated organics, and high-temperature reagents—where standard polypropylene (PP) or polyethylene (PE) tips would degrade, leach, or deform. Unlike conventional thermoplastic tips, PFA maintains dimensional stability across a wide thermal range (–200 °C to +260 °C) and demonstrates ultra-low extractables, making it suitable for ICP-MS, GC-MS, and EPA Method-compliant workflows requiring sub-part-per-trillion contamination control.

Key Features

• Ultra-High Chemical Resistance: Resists corrosion from hydrofluoric acid, piranha solution, molten salts, and organic solvents such as chloroform, DMF, and DMSO without swelling, cracking, or surface etching.
• Low Extractables & Leachables: Certified to meet USP Class VI and ISO 10993-5 biocompatibility standards; validated for trace elemental analysis with <0.1 ng/mL metal background (tested per ASTM D5127).
• Precision Fit & Seal Integrity: Tapered conical geometry and optimized wall thickness ensure consistent, leak-free engagement with Eppendorf, Thermo Fisher, DLAB, and Sartorius pipettors—verified via ISO 8655-5 mechanical seal testing at 100%, 50%, and 10% nominal volume.
• Thermal & Mechanical Stability: Maintains tip integrity during autoclaving (121 °C, 20 min), freeze-thaw cycling (–80 °C to +25 °C), and high-speed centrifugation (≥15,000 × g).
• OEM-Compatible Design: Manufactured to original equipment manufacturer dimensional tolerances (±0.02 mm on critical fit diameters); compatible with electronic pipettes featuring auto-detection and tip ejection force optimization.

Sample Compatibility & Compliance

These PFA tips are validated for use with aqueous, organic, and mixed-phase samples containing volatile analytes (e.g., VOCs), chelated metals (e.g., EDTA-Cu), and viscous matrices (up to 500 mPa·s). They comply with ISO 8655-5 (pipette tip performance), ASTM E2792 (low-level metal contamination in labware), and EU Directive 2002/72/EC for food contact materials (when specified). For regulated environments, sterile versions are gamma-irradiated (25 kGy) and supplied with full CoA, CoC, and EO sterilization validation documentation. Traceability supports GLP/GMP audit requirements including FDA 21 CFR Part 11–compliant batch records.

Software & Data Management

While PFA tips are passive consumables, their performance is integrated into digital lab workflows via compatibility with LIMS and ELN platforms. Batch-specific certificates of analysis include QR-coded traceability linking raw material lot numbers, extrusion parameters, and QC test reports (ICP-OES residual metal screening, FTIR identity verification, and visual defect inspection per ISO 13485 Annex A). Custom serialization and RFID tagging are available for automated inventory management in high-throughput core facilities.

Applications

• Trace metal analysis (ICP-MS, ICP-OES) requiring sub-ppt contamination limits
• HPLC/GC sample preparation involving aggressive mobile phase solvents
• Radiochemistry labs handling [¹⁸F]FDG or other PET radiotracers
• Electrolyte formulation for lithium-ion battery R&D
• High-purity semiconductor wafer cleaning process validation
• Environmental monitoring under EPA Methods 200.8, 6020B, and ISO 17294-2

FAQ

Are these tips certified sterile?
Sterile versions are available upon request, gamma-irradiated to SAL 10⁻⁶ and supplied in ISO 11140-1 compliant packaging with full sterility assurance documentation.

Do they fit electronic pipettes with tip-sense functionality?
Yes—dimensional compliance ensures reliable detection by Eppendorf Xplorer®, Thermo Fisher E1-ClipTip®, and DLAB QuickDrop® systems.

Can they be autoclaved repeatedly?
PFA tips withstand up to five autoclave cycles (121 °C, 15–20 min) without measurable deformation or increased extractables.

What is the shelf life under ambient storage?
Unopened, dry-stored at 15–25 °C, the recommended shelf life is 36 months from manufacture date.

Is custom packaging or labeling available for contract manufacturing?
Yes—Binzhenghong supports private-labeling, rack configuration (e.g., 96-well PCR format), and regulatory-compliant labeling per 21 CFR Part 11 and EU MDR Annex I requirements.
