Polypropylene (PP) Syringe Filters - SF18019

Analytical laboratories processing organic solvents and non-aqueous samples require filtration solutions that resist chemical attack while providing reliable clarification performance. The SF18019 meets these industry demands with a 0.45 µm hydrophobic polypropylene membrane engineered for aggressive solvent compatibility and micro-volume sample processing. Your operations benefit from ultra-compact 4mm diameter construction that minimizes holdup to just 1 µL while the naturally hydrophobic surface repels water and processes organic mobile phases efficiently across chromatography, spectroscopy, and chemical analysis applications.

Key Membrane Characteristics

0.45 µm polypropylene membrane delivers clarification with exceptional chemical resistance across acids, bases, and organic solvents
0.125 cm² filtration area in the ultra-compact 4mm diameter handles up to 1 ml sample volumes for micro-scale processing
7.40 psi bubble point ensures membrane integrity while the 140-260 µm thickness provides mechanical strength during filtration
Hydrophobic surface properties naturally repel aqueous solutions while processing organic solvents without requiring membrane pre-wetting
Broad solvent compatibility supports aggressive chemicals, including alcohols, ketones, chlorinated solvents, and hydrocarbon mixtures

Key Construction Characteristics

Durable polypropylene housing provides excellent chemical resistance and withstands operating pressures up to 87 psi
1 µL holdup volume preserves precious samples when working with limited quantities or expensive analytical standards
Dual luer-lok/luer slip inlet and outlet connections accommodate standard syringes despite the compact filter dimensions
Autoclavable at 121°C for 30 minutes to support your in-house sterilization protocols when required for specific applications

Your micro-volume workflows gain efficiency from the 4mm format that delivers exceptional sample recovery through minimal holdup volume. The hydrophobic polypropylene membrane resists chemical attack from aggressive solvents while providing consistent clarification performance across diverse organic mobile phases. This nonsterile configuration offers flexibility where you can autoclave filters before use or employ them directly for routine analytical sample preparation in pharmaceutical, environmental, and chemical testing laboratories.
