Whatman Puradisc Nylon Syringe Filters, 0.45 µm, 25 mm, 500/Pk - 6752-2504

Whatman manufactures under Cytiva's quality infrastructure, drawing on a filtration heritage that spans laboratory, environmental, and industrial applications. A syringe filter seats a membrane in a sealed housing that threads onto a standard luer fitting. The nylon matrix resists particle shedding through extended filtration cycles and clarifies particulates at the rated pore size. Polypropylene construction resists chemical degradation from routine sample matrices while holding extractables low for sensitive analyses and routes flow to minimize backpressure in service. When chromatographic methods demand particle-free injections, point-of-use syringe filtration clarifies the sample before it reaches the column.

Technical Specifications

• Absolute pore size rating provides consistent results across filtration protocols
• Broad compatibility with alcohols, aliphatic, and aromatic solvents
• High tensile strength for stability under elevated differential pressures
• Non-sterile for routine clarification and sample prep
• Low extractable contribution to sensitive analytical preparations

Housing Specifications

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

Upstream clarification pays for itself by keeping your columns clear and your analytical day on schedule. Pre-injection filtration protects the resolution your methods depend on by clearing particulates ahead of the column and frits.
