PTFE Hydrophilic Syringe Filters, 0.45um, 4mm, Luer-Lok/Luer Slip, Nonsterile, 200/Pk SKU: SF17507

Polytetrafluoroethylene (PTFE) Syringe Filters - SF17507

Analytical chemistry laboratories, pharmaceutical micro-testing facilities, and precision research organizations require ultra-compact clarification solutions for micro-volume samples where particulate removal is critical without sacrificing precious specimen recovery. Advanced laboratory capabilities demand membrane technology that delivers validated 0.45μm clarification performance while maintaining ultra-minimal dead volume through precision engineering. Engineered with 4mm ultra-compact architecture and hydrophilic PTFE membrane chemistry, this filtration system provides efficient particulate removal through 21.75psi bubble point integrity validation. Design optimization includes 1μL ultra-minimal holdup volume for maximum micro-sample recovery, polypropylene prefilter integration protecting membrane integrity, and controlled 1.5ml flow rate characteristics processing 1ml micro-volume samples with precision suitable for demanding analytical workflows requiring both clarification performance and sample conservation.

Key PTFE Membrane Characteristics
