Hydrophilic Polytetrafluoroethylene (PTFE) Syringe Filters - SF18137

High-volume aqueous sample processing often requires rapid clarification without the complications of membrane pre-wetting or chemical compatibility concerns that slow analytical workflows. Hydrophilic-treated PTFE membrane technology with 0.45µm pore size addresses these challenges through immediate aqueous sample compatibility while maintaining PTFE's exceptional chemical resistance across acids, bases, and diverse solvents. The large 30mm diameter configuration combines 4.9cm² filtration area with integrated polypropylene prefilter to deliver 59ml/min flow rates, enabling efficient processing of cell culture harvests, fermentation broths, and high-particulate samples. You gain the convenience of instant aqueous processing without sacrificing the durability and broad compatibility that makes PTFE the preferred choice for demanding analytical and pharmaceutical clarification applications.

Key Polytetrafluoroethylene (PTFE) Membrane Characteristics

• Hydrophilic surface treatment eliminates pre-wetting requirements, enabling immediate processing of aqueous buffers, biological solutions, and mixed solvent systems without alcohol preparation
• Clarification-grade 0.45µm pore size removes particles and cellular debris while maintaining rapid flow rates for high-volume sample processing in biotechnology and pharmaceutical workflows
• Exceptional chemical resistance maintains stability across diverse pH ranges, organic solvents, strong acids, bases, and reactive compounds throughout challenging analytical applications
• Low protein binding characteristics preserve sample integrity and prevent adsorptive losses during filtration of biological matrices, enzyme solutions, and protein-containing formulations
• Integrated polypropylene prefilter captures coarse particles and extends membrane life when processing cell culture harvests, fermentation broths, and high-particulate analytical samples

Key Construction Characteristics

• Polypropylene housing construction provides comprehensive chemical compatibility and autoclave capability at 121°C for user sterilization protocols when processing demands
• Large 30mm diameter with expansive 4.9cm² filtration area maximizes throughput for high-volume samples requiring rapid clarification without multiple filter changes
• Moderate 100µL holdup volume balances sample recovery with processing efficiency for routine analytical workflows where conservation and speed are both important
• Dual Luer-Lok and Luer Slip compatibility accommodates standard laboratory syringes from 10ml to 60ml for flexible integration across diverse sample volumes

Designed for your high-volume clarification requirements, these hydrophilic PTFE filters deliver operational reliability through 87psi burst pressure while processing challenging samples at flow rates up to 59ml/min. You achieve consistent results across diverse chemical environments with PTFE's exceptional resistance to acids, bases, and solvents. Autoclavable construction supports your sterilization protocols, and the integrated prefilter extends membrane life when processing particulate-laden samples in biotechnology and pharmaceutical applications.
