Where other materials leach plasticisers, swell in solvents, or fail autoclave sterilisation cycles, PTFE remains chemically inert, dimensionally stable, and extractables-free, across the full range of pharmaceutical production conditions. ### Why PTFE Dominates Pharmaceutical Manufacturing - Chemical Resistance: withstands concentrated acids, bases, strong oxidisers, and all common pharmaceutical solvents without swelling, degradation, or leaching. - Temperature Stability: serviceable from –200°C to +260°C. Survives steam autoclave sterilisation at 134°C and dry heat sterilisation at 170°C. - Ultra-Low Extractables: virgin PTFE generates negligible extractable compounds into pharmaceutical media, supporting drug purity. - FDA Compliance: 21 CFR 177.1550 compliant as standard; USP Class VI available for critical injectable applications. - Non-stick Surface: prevents product adhesion and simplifies CIP cleaning cycles, reducing cleaning validation burden. ### Application and Grade Selection | Application | Recommended Grade | | --- | --- | | API and solvent transfer lines | Virgin PTFE, FDA grade | | Peristaltic pump tubing | Thin wall PTFE, precision tolerance | | WFI and purified water distribution | PFA ultra-pure or PTFE | | CIP/SIP flexible hose connections | PTFE SS304 braided hose, smooth bore | | Bioprocessing and fermentation | PFA or PTFE, USP Class VI | | Chromatography system tubing | Thin wall PTFE, low dead volume | ### Sterilisation Compatibility PTFE withstands all standard pharmaceutical sterilisation methods. Steam autoclaving at 121°C or 134°C causes no dimensional change or chemical alteration. Dry heat sterilisation to 170°C is routinely used for thin-wall tubing. Gamma irradiation is generally not recommended for PTFE: it induces molecular chain scission and embrittlement at doses above ~10 kGy. For gamma-irradiated processes, specify FEP or PFA. ### Expected Service Life With correct installation and appropriate chemical and thermal loading, PTFE pharmaceutical tubing achieves a service life of 5–10 years in static installations. Peristaltic pump tubing life is shorter, typically 6–18 months depending on pump speed, tubing OD, and compression ratio. Plan replacement schedules based on visual inspection for compression set and bore distortion rather than fixed calendar intervals. Compliance Checklist For pharmaceutical applications specify: Virgin PTFE (not regrind) · FDA 21 CFR 177.1550 certification · USP Class VI for direct drug contact · Batch traceability documentation · Certificate of conformance with each shipment. Advanced Fluro provides all of these as standard for pharmaceutical-grade orders.
