Pura Disc 13mm PVDF Syringe Filters, 0.2um, 500 Pk
Whatman SKU: 6792-1302

Whatman Puradisc PVDF Syringe Filters, 0.2 µm, 13 mm, 500/Pk - 6792-1302

Whatman's established manufacturing platform delivers the consistency and lot-level documentation that analytical laboratories require. A syringe filter seats a membrane in a sealed housing that threads onto a standard luer fitting. The hydrophilic PVDF membrane draws aqueous mobile phases through without pre-wetting and resists HPLC mobile phases, alcohols, and mild hydrocarbons. The polypropylene housing holds a reliable seal against the membrane edge and resists degradation from routine sample matrices. 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 gives consistent results across protocols
• Ultra-low protein binding preserves dilute analytes for maximum recovery
• Resists HPLC mobile phases, alcohols, and mild hydrocarbons
• Thin membrane structure sustains high flow for fast sample throughput
• Mechanically durable membrane holds integrity under filtration pressure

Housing Specifications

• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Low extractable contribution protects sensitive downstream analyses
• Optimized internal geometry minimizes backpressure in service
• Resists aqueous acids, bases, and alcohols in routine sample prep

Filtering particulates upstream protects the column investment your methods depend on. Reliable particulate removal protects your instruments and your data across reagent, buffer, and mobile-phase preparation.
