Hydrophilic PTFE Syringe Filter, 0.22µm, 13mm, Sterile, Luer-Lok Compatible - 100/Pk SKU: LE-IWT-ES10039

Featuring hydrophilic PTFE membrane technology delivering exceptional chemical compatibility for both aqueous and organic sample filtration applications. These sterile filters excel with acids and bases where traditional membranes fail, while maintaining 0.22µm absolute retention for reliable particle removal and microbial sterilization. Individual blister packaging ensures sterility integrity with Luer-Lok® compatibility providing secure, leak-free connections during critical sample preparation workflows.

Key PTFE Membrane Characteristics

Hydrophilic surface treatment eliminates pre-wetting requirements for immediate aqueous sample processing
Chemical resistance spans pH 1-14 range enabling filtration of harsh acids, bases, and aggressive organic solvents
0.22µm absolute pore rating captures bacteria and particulates while maintaining optimal flow rates
Low extractables profile minimizes interference in HPLC and analytical applications
Temperature stability withstands autoclaving and thermal sterilization protocols without membrane degradation

Key Construction Characteristics

Polypropylene housing construction provides chemical inertness and mechanical strength under pressure
Ultrasonic bonding technology ensures leak-proof seal integrity during high-pressure sample processing
13mm diameter delivers 0.092 cm² filtration area optimizing throughput for small sample volumes
Individual sterile blister packaging maintains sterility while enabling easy identification of specifications
Universal Luer-Lok® and slip connections accommodate standard syringes and sampling equipment

These filters accelerate sample preparation workflows by combining hydrophilic wetting with universal solvent compatibility, eliminating the pre-treatment steps required by hydrophobic PTFE alternatives. Ideal for HPLC sample preparation and analytical equipment protection, the sterile individual packaging ensures contamination-free processing while the concentric funnel-shaped barrel design minimizes sample holdup and reduces back pressure. Superior lot-to-lot consistency and validated sterility protocols deliver the reliability demanded by pharmaceutical, biotechnology, and analytical laboratory applications requiring both chemical resistance and microbial security.
