Polytetrafluoroethylene (PTFE) Syringe Filters - SPEC17163

Meeting stringent pharmaceutical and chemical industry requirements for organic solvent clarification, these specialized 0.45µm polytetrafluoroethylene filters demonstrate exceptional capability in removing particles from aggressive chemical solutions. Advanced membrane design engineered for superior chemical resistance delivers consistent clarification performance across acids, bases, alcohols, and aromatic solvents that degrade conventional filtration materials. Precision-manufactured 25mm diameter construction with ISO9001-certified quality standards ensures reliable operation throughout demanding laboratory environments.

Key Polytetrafluoroethylene Membrane Characteristics

• Hydrophobic membrane surface requires pre-wetting with compatible organic solvents before processing aqueous samples, ensuring proper flow initiation
• Outstanding chemical inertness maintains stability when exposed to aggressive laboratory chemicals, including strong acids, caustic bases, and organic aromatics
• Optimal 0.45µm pore architecture provides effective particle removal and sample clarification while maintaining rapid flow rates through viscous solvents
• Extremely low protein binding preserves sample integrity and prevents adsorptive losses during the filtration of sensitive pharmaceutical compounds
• Superior thermal stability enables autoclave sterilization protocols and processing at elevated temperatures up to 80°C operating conditions

Key Construction Characteristics

• High-quality polypropylene housing construction delivers broad chemical compatibility and maintains dimensional stability across temperature variations
• Standard 25mm diameter with expansive 4.9cm² filtration area preserves samples by maximizing membrane surface for efficient processing
• Double luer lock connection interface ensures secure attachment and prevents leakage during organic solvent filtration under pressure
• Burst pressure capability of 116psi provides structural integrity for processing challenging samples under elevated differential pressures

Manufactured according to ISO9001 quality standards, these precision filters provide dependable clarification performance while resisting chemical degradation from your most aggressive laboratory solvents. Advanced polytetrafluoroethylene membrane technology ensures consistent particle removal and maintains reliable flow characteristics, supporting your analytical objectives with superior chemical compatibility.
