Polypropylene (PP) Syringe Filters - SPEC18192

Sterilizing organic solvents and air-sensitive pharmaceutical compounds presents unique challenges when aqueous-compatible membranes would introduce contamination or moisture. Hydrophobic polypropylene membrane technology solves this problem by providing sterile-grade filtration at 0.22 µm while naturally repelling water and maintaining compatibility with aggressive organic solvents. Your ready-to-use sterile filters eliminate preparation time and contamination risks associated with filter handling and sterilization procedures. The double luer lock configuration ensures secure connections during critical sterile processing, while the polypropylene construction throughout delivers uniform chemical resistance for demanding applications.

Key Membrane Characteristics

• 0.22 µm polypropylene membrane delivers sterile-grade filtration for removing bacteria and particulates from organic solvents and non-aqueous solutions
• 4.9 cm² filtration area in the 25mm diameter provides efficient throughput for routine sterile processing applications
• Hydrophobic surface properties naturally resist aqueous contamination while allowing organic solvents and gases to pass freely
• Maximum operating pressure of 72.5 psi with 116 psi burst rating ensures safe operation during sterile pharmaceutical processing
• Temperature rating to 80°C accommodates warm solvent filtration and elevated temperature processing requirements

Key Construction Characteristics

• Polypropylene housing material matches membrane composition for consistent chemical resistance throughout the sterile flow path
• Double luer lock connections on inlet and outlet ports prevent disconnection during critical sterile operations
• 25mm diameter format balances filtration capacity with practical size for manual syringe-driven applications
• Individually packaged sterile units arrive ready for immediate use in your aseptic processing workflows

Each sterile filter arrives individually packaged and ready for immediate use in your aseptic workflows, eliminating preparation steps and reducing contamination risk. The hydrophobic polypropylene membrane maintains structural integrity across diverse organic solvents while providing reliable bacterial retention. Your sterile processing benefits from the consistent performance and broad chemical compatibility that polypropylene delivers, enabling confident sterilization of challenging non-aqueous solutions and gas streams in critical pharmaceutical and research applications.
