PTFE Hydrophilic Syringe Filters, 0.45um, 4mm, Luer-Lok/Luer Slip, Sterile, 100 /Pk SKU: SF18246

Polytetrafluoroethylene (PTFE) Syringe Filters - SF18246

Pharmaceutical micro-analytical laboratories, clinical diagnostic facilities, and precision research organizations require ultra-low volume clarification solutions for precious samples where contamination control is critical but sterile filtration is not necessary. Advanced laboratory capabilities demand membrane technology that delivers validated 0.45μm particulate removal while maintaining contamination-free handling through ready-to-use sterile packaging. Engineered with ultra-compact 4mm architecture and hydrophilic PTFE membrane chemistry, this filtration system provides immediate-use clarification performance through 21.75psi bubble point integrity validation. Design optimization includes individual sterile packaging eliminating contamination risks, 1μL ultra-minimal holdup volume for maximum precious sample recovery, and polypropylene prefilter integration protecting membrane integrity while processing 1ml micro-volume samples with 1.5ml controlled flow rate characteristics.

Key PTFE Membrane Characteristics

Validated 0.45μm Clarification Performance - Removes interfering particles while maintaining dissolved component passage for accurate micro-volume analytical measurements
Hydrophilic Surface Engineering - Modified fluoropolymer eliminates pre-wetting requirements, enabling immediate processing of aqueous micro-samples
Chemical Stability Platform - Resists degradation from analytical solvents while maintaining documented incompatibility awareness for operational safety
Low Protein Binding Characteristics - Preserves concentration of proteins and biologics through minimal surface adsorption in micro-volume processing
21.75psi Bubble Point Validation - Ensures consistent pore structure integrity and clarification performance across manufacturing batches

Key Construction Characteristics

1μL Ultra-Minimal Holdup Volume - Optimizes yield through precision dead space engineering, maximizing recovery of ultra-precious micro-specimens
Ready-to-Use Sterile Packaging - Individual sterile units eliminate contamination risks and pre-handling delays in sensitive workflows
Ultra-Compact 4mm Platform - 0.125cm² effective area provides precise clarification control for micro-volume samples requiring clean handling
Integrated Polypropylene Prefilter - Protects primary membrane from particulate damage while maintaining controlled 1.5ml flow characteristics

Built for your most precious micro-volume clarification applications requiring contamination control, this hydrophilic PTFE system delivers structural integrity through 87psi operational ratings while maintaining validated particulate removal. Your laboratory achieves maximum sample recovery through 1μL ultra-minimal holdup design and immediate processing capability through ready-to-use sterile packaging, while the robust prefilter construction ensures consistent clarification performance across demanding micro-analytical workflows where every microliter represents irreplaceable research value.
