PTFE Syringe Filter 0.22μm 13mm & 30mm | Globe Scientific

Engineered for precision laboratory filtration, this PTFE Hydrophilic syringe filter delivers reliable 0.22μm particle retention across multiple diameter and sterility configurations. Hydrophilic membrane properties ensure consistent flow rates for hplc/gc sample prep workflows. Constructed with polypropylene housing featuring female Luer-Lok inlet and male Luer slip outlet, each filter provides secure, leak-free connections during critical sample preparation.

PTFE Syringe Filter 0.22μm — Features and Benefits

• Membrane: PTFE Hydrophilic — hydrophilic, 0.22μm pore size for sterilization-grade particle removal at 0.22μm, capturing bacteria and microorganisms
• Diameters: 13mm & 30mm — 13mm for small volumes under 10mL, 30mm for larger volumes up to 100mL
• Housing: Polypropylene (PP) with color-coded ring for rapid membrane identification
• Sterility: Sterile & Non-Sterile — sterile units are gamma irradiated to SAL 10⁻⁶, individually wrapped, RNase/DNase free; non-sterile units are bulk packed for high-throughput use
• Protein Binding: Low — minimizes sample loss during filtration of sensitive biological samples
• pH Range: 1-14 — compatible with Aggressive solvents, strong acids, strong bases

Quality Assurance and Compliance

Manufactured under ISO 9001 quality management systems, Globe Scientific syringe filters undergo rigorous testing including bubble point verification and bacterial challenge validation. Sterile units are gamma irradiated to SAL 10⁻⁶ and individually wrapped to maintain sterility assurance. PTFE Hydrophilic membrane offers broad chemical compatibility across aqueous and organic solvent systems, making it preferred for HPLC and GC sample preparation. Polypropylene housing resists cracking and chemical degradation across the full pH 1-14 operating range, ensuring reliable performance with aggressive sample matrices.

Frequently Asked Questions

What is a 0.22μm PTFE syringe filter used for?

A 0.22μm syringe filter with PTFE Hydrophilic membrane removes particles at sterilization grade, capturing bacteria and microorganisms from liquid samples. Hydrophilic wetting enables reliable filtration of aqueous and compatible solvent systems in laboratory workflows.

Should I choose 13mm or 30mm diameter?

Select 13mm for sample volumes under 10mL — the smaller diameter minimizes hold-up volume and dead volume loss. Choose 30mm for larger volumes up to 100mL where higher flow rates reduce filtration time. Both diameters use identical PTFE Hydrophilic membrane chemistry at 0.22μm pore size.
