PP Syringe Filters w/ 3 Pre-Filters, 0.45 um, 25mm, Nonsterile, 100/Pk
Tisch SKU: SF18306

Tisch Scientific Polypropylene (PP) Syringe Filters, 0.45 µm, 25 mm, 100/Pk - SF18306

Tisch Scientific keeps ordering simple, turning quotes and questions around quickly. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. Polypropylene pairs hydrophobic behavior with broad chemical resistance while delivering nominal retention with high dirt-loading capacity and resists a broad range of organic solvents, acids, and bases. The PP housing sustains efficient flow on viscous samples while holding extractables low for sensitive analyses and prevents sample bypass under rated operating pressure. When chromatographic methods demand particle-free injections, point-of-use syringe filtration clarifies the sample before it reaches the column.

Technical Specifications

• Hydrophobic matrix suits solvent and non-aqueous sample streams
• Low binding with nominal depth retention and high dirt-loading capacity
• Sustains throughput on particulate-laden solvent samples
• High resistance to organic solvents, acids, and bases
• Low extractables protect sensitive downstream analyses

Housing Specifications

• Plasticizer-free polyolefin construction keeps the fluid path clean
• Optimized internal geometry minimizes backpressure in service
• Stable across the full aqueous pH range in routine sample work
• Thermal-bonded construction keeps adhesives out of the fluid path

Clarifying organic mobile phases before injection protects your chromatography while standing up to the solvent. Solvent-stream filtration handles the solvents and reagents your methods rely on from organic mobile-phase prep through reagent clarification.
