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

Engineered for precision laboratory filtration, this PTFE Hydrophobic syringe filter delivers reliable 0.22μm particle retention across multiple diameter and sterility configurations. Hydrophobic membrane properties ensure consistent flow rates for gas venting 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 Hydrophobic Syringe Filter 0.22μm — Features and Benefits

• Membrane: PTFE Hydrophobic — hydrophobic, 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: Non-Sterile — bulk packed for cost-effective high-volume laboratory workflows
• Protein Binding: Low — minimizes sample loss during filtration of sensitive biological samples
• pH Range: 1-14 — compatible with Non-polar solvents, gases, venting applications

Frequently Asked Questions

What is a 0.22μm PTFE Hydrophobic syringe filter used for?

A 0.22μm syringe filter with PTFE Hydrophobic membrane removes particles at sterilization grade, capturing bacteria and microorganisms from liquid samples. Hydrophobic wetting enables reliable filtration of non-polar solvent and gas 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 Hydrophobic membrane chemistry at 0.22μm pore size.
