Non-Sterile, 0.45μm, 13 mm, Red, PTFE Hydrophilic

Cost-effective high-quality filtration that decreases instrument downtime and improves the reliability of experimental results.

Diamond PureFlow syringe filters feature a polypropylene housing secured around a membrane with a molded polypropylene sealing ring. This double injection molding provides a durable filter built to withstand pressures higher than most alternatives.


  • Performance: High flow rates and low absorption membranes minimize sample loss.
  • Simplicity: Color-coded rings allow easy identification of membrane and filter media type. Each filter is clearly marked with a code that indicates membrane material and pore size.
  • Strength: The bonded outer ring provides strength under higher pressure.
  • Efficiency: Integral PP pre-filter provides both fast filtration and high flow rates.
  • Quality: Manufacturing process certified to ISO 9001 standards.

Available in a variety of membrane types, filter diameters, and membrane porosities to meet nearly all applications.
