PVDF Syringeless Filters - AV125NPUAQU

For analysts clearing high sample volumes, syringeless filters combine the membrane and prefilter into one disposable format, shortening setup and keeping the prep workflow uninterrupted. Ultra-low-binding PVDF preserves dilute proteins and analytes in the filtrate while suiting HPLC sample preparation and aqueous clarification and holds consistent absolute retention at the rated pore size. Polypropylene construction resists chemical degradation from routine sample matrices while holding extractables low for sensitive analyses and sustains efficient flow on viscous samples. Cleaner, more uniform injections follow, giving the method the reproducibility that quantitative analysis depends on.

Technical Specifications

• Resists HPLC mobile phases, alcohols, and mild hydrocarbons
• Ultra-low protein binding preserves dilute analytes for maximum recovery
• Low extractables preserve a clean chromatographic baseline
• Thin membrane structure sustains high flow for fast sample throughput
• Absolute pore size rating gives consistent results across protocols

Housing Specifications

• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Thermal-bonded construction keeps adhesives out of the fluid path
• Optimized internal geometry minimizes backpressure in service
• Resists aqueous acids, bases, and alcohols in routine sample prep

Sealing each sample securely from preparation through injection keeps your chromatographic data trustworthy. Dependable vial and closure performance protects your samples through every injection from sample preparation through the final run in the queue.

• UHPLC Prep Workflow - Integrated plunger and membrane filter sub-micron particles in one step, meeting stringent UHPLC injection purity requirements.
• Pharmaceutical QC Testing - Content uniformity and dissolution samples are clarified in one step, reducing handling before chromatographic injection.
• Bioanalytical Sample Cleanup - Low-binding membranes clarify plasma and serum extracts, retaining drug analytes for accurate quantitation.
• HPLC Sample Prep - Plunger-driven filtration removes particulates from analytical samples, protecting columns from clogging and back pressure.
• Solubility Assay Filtration - Positive-pressure filtration cleanly clarifies small sample volumes, supporting accurate solubility determination.
• Column Lifetime Extension - Consistent sub-micron particle removal before injection reduces column contamination and back pressure buildup.
