PTFE Hydrophilic Syringe Filters, 0.22um, 25mm, Luer-Lok/Luer Slip, Sterile, 100 /Pk SKU: SF18238

Polytetrafluoroethylene (PTFE) Syringe Filters - SF18238

Advanced fluoropolymer membrane technology delivers 0.22μm absolute bacterial retention with 43.51psi bubble point validation, ensuring complete sterile filtration performance across demanding laboratory applications. Hydrophilic surface modification enables immediate aqueous sample processing while maintaining the inherent chemical resistance characteristics of PTFE chemistry. Critical aseptic processing applications, pharmaceutical quality control testing, and sterile research protocols require immediate-use filtration capabilities without pre-sterilization delays or contamination risks. Quality assurance protocols validate consistent membrane integrity through rigorous bubble point testing, while 100μL holdup volume specifications ensure optimal sample recovery rates for valuable analytical specimens and research materials.

Key PTFE Membrane Characteristics

• Validated Sterile Filtration Performance - 0.22μm pore size with 43.51psi bubble point provides absolute bacterial removal for critical applications
• Hydrophilic Surface Treatment - Proprietary modification eliminates pre-wetting requirements, enabling direct aqueous sample processing
• Chemical Stability - Resists aggressive solvents and maintains membrane integrity with known incompatibilities for bases, esters, ethers, and ketones
• Low Protein Binding - Maintains concentration of sensitive biologics and therapeutic proteins throughout filtration processes
• Membrane Thickness Control - 80-140μm engineered depth provides structural durability with consistent flow performance

Key Construction Characteristics

• 100μL Holdup Volume - Minimizes loss of precious samples through optimized dead volume design for maximum recovery efficiency
• 25mm Diameter Platform - 4.08cm² filtration area supports efficient processing of medium-volume samples up to 50ml capacity
• Dual Luer Interface - Universal Luer-Lok/Luer Slip compatibility accommodates all standard laboratory syringe configurations
• Sterile Packaging - Individual sterile units eliminate pre-sterilization steps and reduce contamination risks in critical applications

Engineered for your most critical sterile processing requirements, this hydrophilic PTFE system provides structural integrity through 87psi operational limits while delivering quality assurance through validated bubble point specifications. Your laboratory maintains the highest sterility standards through ready-to-use packaging, while the optimized holdup design ensures maximum recovery of your valuable samples and research investments.
