Polypropylene (PP) Syringe Filters - SPEC18191

Hydrophobic polypropylene at 5.0 µm pore size delivers maximum flow rates for extremely particulate-laden samples requiring initial clarification before analytical processing. This largest pore size configuration excels in applications where rapid throughput matters more than fine particle retention, removing debris and suspended solids that would clog downstream equipment. You gain exceptional chemical resistance to aggressive solvents, acids, and bases that compromise alternative membrane materials. The robust construction with double luer lock connections ensures secure operation even when processing viscous matrices under pressure.

Key Membrane Characteristics

• 5.0 µm polypropylene membrane provides the highest flow rates for rapid processing of heavily contaminated environmental and industrial samples
• 4.9 cm² filtration area in the 25mm diameter handles extreme particulate loads while maintaining manageable pressure requirements
• Hydrophobic surface properties naturally shed aqueous solutions while allowing organic solvents and non-polar compounds to flow freely
• Maximum operating pressure of 72.5 psi with 116 psi burst rating accommodates challenging samples without membrane rupture concerns
• Temperature capability to 80°C supports elevated temperature filtration for warm solvents and thermally processed samples

Key Construction Characteristics

• Polypropylene housing throughout delivers consistent chemical compatibility from membrane surface to outlet connection
• Double luer lock fittings on both ports prevent disconnection during filtration of pressurized or viscous sample matrices
• 25mm diameter platform offers practical filtration capacity for manual syringe operations without excessive size
• Nonsterile supply format allows autoclavable treatment at 121°C for 30 minutes when your protocols require sterile conditions

Your nonsterile filters accommodate gamma irradiation at 5 kGy for 8 hours or autoclave sterilization, integrating seamlessly into protocols requiring sterile operation. The hydrophobic polypropylene membrane resists chemical attack from diverse solvents, though you should minimize extended exposure to esters, hexane, toluene, benzene, and dichloromethane. Each filter combines maximum throughput with protective prefiltration, enabling you to process challenging samples rapidly while safeguarding finer downstream filtration stages and analytical instrumentation.
