PTFE Hydrophilic Syringe Filters, 1.0um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk SKU: SF18053

Polytetrafluoroethylene (PTFE) Syringe Filters - SF18053

Featuring hydrophilic PTFE membrane technology at 1.0μm pore size, engineered for high-throughput clarification applications where rapid processing and chemical compatibility are essential. Advanced surface modification eliminates pre-wetting protocols while maintaining the superior chemical resistance characteristics inherent to fluoropolymer chemistry. Analytical sample preparation, environmental monitoring, and industrial process control applications demand efficient particulate removal without compromising sample integrity or introducing extractables that interfere with downstream analysis. Construction specifications include 25mm diameter platform with 4.08cm² filtration area, polypropylene housing rated to 60°C, and integrated prefilter protection delivering 70ml flow rate capabilities with 100μL holdup volume optimization.

Key PTFE Membrane Characteristics

• 1.0μm Clarification Performance - Removes larger particulates and debris while allowing passage of smaller particles and dissolved components
• Hydrophilic Surface Engineering - Modified fluoropolymer eliminates alcohol pre-wetting requirements for immediate aqueous sample processing
• Superior Chemical Compatibility - Stable operation with aggressive solvents while maintaining documented incompatibilities with bases, esters, ethers, and ketones
• Low Extractables Profile - Maintains concentration integrity and reduces interference in analytical measurements and sensitive assays
• 4.35psi Bubble Point Validation - Ensures consistent pore structure and filtration performance across manufacturing lots

Key Construction Characteristics

• v100μL Holdup Volume - Maximizes recovery of valuable samples through optimized dead volume design for analytical applications
• 25mm High-Capacity Platform - 4.08cm² effective area enables processing of medium to large sample volumes up to 50ml efficiently
• Dual Connection Interface - Universal Luer-Lok/Luer Slip compatibility provides seamless integration with laboratory syringe systems
• Polypropylene Prefilter Integration - Protects the primary membrane from particulate overloading while extending operational lifetime

Designed for your demanding clarification requirements, this hydrophilic PTFE system delivers structural integrity through 87psi burst pressure margins while providing rapid throughput at 70ml flow rates. Your laboratory operations benefit from immediate sample processing without pre-conditioning steps, while the robust prefilter design ensures consistent performance across extended filtration campaigns and challenging sample matrices.
