Polytetrafluoroethylene (PTFE) Syringe Filters - SF18252

Particulate contamination in medium-volume analytical samples creates processing bottlenecks where rapid clarification is essential but sterile filtration is not required, yet immediate-use capability eliminates workflow delays. Traditional non-sterile filters require time-consuming pre-sterilization steps when contamination control matters, creating unnecessary risks and extending processing timelines. Advanced hydrophilic PTFE membrane technology at 1.0μm combines ready-to-use sterile packaging with high-throughput clarification capabilities, eliminating pre-processing delays while delivering reliable particulate removal. Technical specifications include 4.35psi bubble point validation ensuring consistent 1.0μm pore structure, 25mm platform with 4.08cm² filtration area, and 100μL holdup volume delivering exceptional 70ml flow rates with 50ml throughput capacity for demanding clarification workflows.

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 maintaining documented incompatibility awareness
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 70ml flow efficiency

When you need rapid clarification without the wait, this hydrophilic PTFE system gives you immediate productivity—no pre-wetting, no preparation delays. You get sterile packaging that eliminates contamination risks during handling, while the 87psi burst pressure means you can push samples through quickly at 70ml flow rates. The integrated prefilter protects your membrane from premature clogging, so you process more samples before needing replacements. For medium-volume work where clean handling matters but sterilization isn't required, you're getting the throughput and reliability your workflow demands.
