Polytetrafluoroethylene (PTFE) Syringe Filters - SF18252

Hydrophilic Polytetrafluoroethylene (PTFE) Syringe Filters Featuring advanced hydrophilic PTFE membrane technology with a 1.0µm pore size for the rapid clarification of aqueous and organic samples without pre-wetting. The 25mm diameter delivers exceptional 70 ml/min flow rates through a 4.08cm² filtration area, eliminating processing bottlenecks. Supplied in sterile packaging, these units ensure a contaminant-free device for critical workflows, with a 4.35psi bubble point validation confirming consistent pore structure for reliable particulate removal.

Key PTFE Membrane Characteristics

• High-Throughput 1.0µm Clarification - Removes larger particulates and debris while maintaining rapid flow characteristics for time-sensitive processing
• Hydrophilic Surface Treatment - Modified fluoropolymer chemistry eliminates pre-wetting procedures, enabling immediate aqueous sample processing
• Chemical Resistance Platform - Stable operation with aggressive analytical solvents while minimizing chemical interaction
• Low Protein Binding Surface - Maintains concentration of biologics and proteins through minimal adsorption during clarification processes
• 4.35psi Bubble Point Validation - Ensures consistent membrane pore structure and filtration performance across production batches

Key Construction Characteristics

• 100µL Holdup Volume - Minimizes loss through optimized dead space design, balancing sample recovery with processing efficiency
• Ready-to-Use Sterile Packaging - Individual sterile units eliminate contamination risks and pre-sterilization delays in critical workflows
• 25mm Medium-Volume Platform - 4.08cm² effective area enables processing of medium to large sample volumes with 50ml capacity
• Integrated Polypropylene Prefilter - Extends membrane operational life through particulate protection while maintaining 70 ml/min flow efficiency

Engineered for rapid clarification without the wait, this hydrophilic PTFE system enables immediate productivity without pre-wetting delays. The pre-sterilized packaging eliminates background contamination risks during handling. With an 87psi burst pressure rating, you can process samples efficiently at 70 ml/min flow rates. The integrated prefilter safeguards the membrane against premature clogging, ensuring reliable throughput for medium-volume applications requiring clean, consistent handling.
