Polypropylene Syringe Filters, 0.22 um, 25mm, Double Luer Lock, PP Housing, Nonsterile, 100/Pk SKU: SPEC18187

Polypropylene (PP) Syringe Filters - SPEC18187

Hydrophobic polypropylene membrane technology delivers reliable filtration performance for aggressive organic solvents and air-sensitive samples in your laboratory. The 0.22 µm pore size provides sterilization-grade filtration while maintaining chemical compatibility with challenging solutions that would degrade other membrane materials. You get consistent throughput with minimal protein binding, making these filters ideal for HPLC mobile phase preparation and solvent-based sample processing. Double luer lock connections on both inlet and outlet ports ensure secure attachment to syringes and receiving vessels, preventing disconnection during high-pressure applications.

Key Membrane Characteristics

• 0.22 µm polypropylene membrane provides sterilization-grade filtration with exceptional chemical resistance to aggressive solvents
• 4.9 cm² filtration area in the 25mm diameter format delivers 100 ml throughput capacity for your sample processing needs
• Hydrophobic surface properties naturally repel aqueous solutions while allowing organic solvents and gases to pass through efficiently
• Flow rate of 160 ml/min at 10 psi ensures rapid processing without compromising filtration quality or membrane integrity
• Maximum operating pressure of 72.5 psi with 116 psi burst pressure provides a safety margin for your demanding applications

Key Construction Characteristics

• Polypropylene housing construction matches membrane material for uniform chemical compatibility throughout the entire filter assembly
• 100 µL holdup volume minimizes sample loss, particularly important when working with expensive reagents or limited sample volumes
• Double luer lock connections on both inlet and outlet provide secure, leak-free operation during manual and automated processing
• Maximum operating temperature of 80°C accommodates warm solvent filtration and thermal processing requirements

Your nonsterile filters arrive autoclavable for integration into your sterilization protocols, accommodating 121°C treatment for 30 minutes or gamma irradiation at 5 kGy for 8 hours. The hydrophobic polypropylene membrane maintains structural integrity across a broad chemical compatibility range, though you should avoid extended contact with esters, hexane, toluene, benzene, and dichloromethane which may compromise performance. Each filter delivers consistent results through its engineered flow path that balances throughput speed with filtration efficiency.

Hydrophobic

• Mobile Phase Preparation - HPLC and UHPLC solvents where hydrophobic membranes prevent aqueous contamination and ensure chromatographic performance
• Organic Solvent Filtration - Aggressive chemicals, including alcohols, acetone, and solvents incompatible with other membrane materials
• Air-Sensitive Sterilization - Pharmaceutical compounds and reagents requiring inert gas blanketing during processing to prevent oxidation
• Instrumental Analysis Prep - Challenging samples with particulates, protecting expensive analytical equipment from fouling, and maintaining performance
• Gas Chromatography Samples - Applications where residual water would interfere with separation quality or damage column performance
• Polymer Solution Filtration - Non-aqueous coating solutions and preparations in materials science, requiring particulate-free formulations
