Polypropylene Syringe Filters, 0.45um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk
Tisch SKU: SF14691

Tisch Scientific Polypropylene (PP) Syringe Filters, 0.45 µm, 25 mm, 100/Pk - SF14691

Tisch Scientific works with established filtration manufacturers to ensure reliable quality and performance. Under hand pressure from the syringe, the membrane captures particulates as the sample passes through. Polypropylene keeps binding low while capturing particulates through its depth while repelling water in vent and solvent service and resists a broad range of organic solvents, acids, and bases. The polypropylene housing holds a reliable seal against the membrane edge and resists aqueous acids, bases, and alcohols. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

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

Housing Specifications

• Optimized internal geometry minimizes backpressure in service
• Low extractable contribution protects sensitive downstream analyses
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Medical-grade polypropylene with broad chemical compatibility

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 so your filter holds its integrity through the run.
