Polytetrafluoroethylene (PTFE) Syringe Filters - SPEC18157

Hydrophilic PTFE at 0.45µm gives you aqueous clarification with PTFE's chemical resistance but without pre-wetting hassles. You skip the alcohol prep entirely—the surface treatment lets you process water-based samples immediately. This gamma-sterilized 25mm format arrives ready for contamination-sensitive work, eliminating preparation delays when clean handling matters. The 4.08cm² filtration area handles standard sample volumes while maintaining rapid flow through biological matrices. For routine aqueous clarification in pharmaceutical and biotechnology labs, you get PTFE's durability in a sterile, ready-to-use aqueous format that simplifies your workflow.

Key Polytetrafluoroethylene Membrane Characteristics

• Specialized hydrophilic treatment eliminates pre-wetting requirements, enabling immediate processing of aqueous biological samples, pharmaceutical solutions, and mixed media systems
• Outstanding chemical inertness maintains stability when exposed to diverse laboratory chemicals while providing compatibility with both organic solvents and aqueous solutions
• Strategic 0.45µm pore configuration provides effective particle removal and sample clarification while maintaining rapid flow rates through aqueous biological matrices
• Extremely low protein binding preserves biomolecule integrity and prevents adsorptive losses during clarification of sensitive pharmaceutical and biological preparations
• Superior mechanical durability withstands high differential pressures without compromising clarification performance or membrane reliability under challenging processing conditions

Key Construction Characteristics

• Lightweight polypropylene housing construction delivers comprehensive chemical compatibility and maintains dimensional stability across temperature ranges up to 80°C
• Standard 25mm diameter with 4.08cm² filtration area maximizes recovery by providing optimal membrane surface for aqueous clarification applications
• Double luer lock interface ensures secure connections and prevents leakage during processing of diverse aqueous samples and analytical protocols
• Safety margin provided by 116psi burst pressure ensures reliable operation under demanding laboratory conditions and elevated differential pressures

When you need aqueous clarification without the pre-wetting hassle, this gamma-sterilized PTFE filter gives you immediate processing. The hydrophilic treatment eliminates alcohol prep steps entirely—just attach and filter your water-based samples. You get PTFE's chemical resistance for diverse solvents while the 0.45μm pore removes particles without clogging on biological matrices. Since it arrives sterile, you're processing contamination-sensitive samples right away. For routine aqueous clarification where chemical compatibility and clean handling both matter, you're getting reliable performance in a ready-to-use format.
