PVDF Syringeless Filters - UN203NPEAQU

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. The hydrophilic PVDF membrane draws aqueous mobile phases through without pre-wetting while tolerating common chromatography solvents without degradation and keeps analyte adsorption low for clean recovery. Polypropylene construction resists chemical degradation from routine sample matrices while holding extractables low for sensitive analyses and holds a reliable seal against the membrane edge. Standardized this way, sample preparation becomes one of the most controlled and repeatable steps in the analytical workflow.

Technical Specifications

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

Housing Specifications

• Medical-grade polypropylene with broad chemical compatibility
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Optimized internal geometry minimizes backpressure in service

Reliable seals and consistent vials keep your autosampler runs clean from the first injection to the last. Dependable vial and closure performance protects your samples through every injection so evaporation and contamination stay out of your data.

Wettability

Hydrophilic

• Pharmaceutical QC Testing - Content uniformity and dissolution samples are clarified in one step, reducing handling before chromatographic injection.
• Protein Precipitation Cleanup - Low protein binding retains analyte integrity when filtering precipitated sample supernatants.
• Direct Sample Filtration - Built-in membrane clarifies the sample in one manual step, cutting transfer steps 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.
• Column Lifetime Extension - Consistent sub-micron particle removal before injection reduces column contamination and back pressure buildup.
