PVDF Syringeless Filters - US503NPUAQU

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 PVDF membrane tolerates common chromatography solvents without degradation and holds consistent absolute retention at the rated pore size. The PP housing prevents sample bypass under rated operating pressure while resisting aqueous acids, bases, and alcohols and keeps the fluid path low in extractable contamination. Standardized this way, sample preparation becomes one of the most controlled and repeatable steps in the analytical workflow.

Technical Specifications

• Low extractables preserve a clean chromatographic baseline
• Hydrophilic surface wets aqueous and HPLC samples without pre-wetting
• Resists HPLC mobile phases, alcohols, and mild hydrocarbons
• Thin membrane structure sustains high flow for fast sample throughput
• Ultra-low protein binding preserves dilute analytes for maximum recovery

Housing Specifications

• Resists aqueous acids, bases, and alcohols in routine sample prep
• Thermal-bonded construction keeps adhesives out of the fluid path
• Optimized internal geometry minimizes backpressure in service
• Low extractable contribution protects sensitive downstream analyses

Sealing each sample securely from preparation through injection keeps your chromatographic data trustworthy. Consistent autosampler-ready components keep your chromatographic methods reproducible with reliable sealing and dimensional consistency.

• Column Lifetime Extension - Consistent sub-micron particle removal before injection reduces column contamination and back pressure buildup.
• HPLC Sample Prep - Plunger-driven filtration removes particulates from analytical samples, protecting columns from clogging and back pressure.
• UHPLC Prep Workflow - Integrated plunger and membrane filter sub-micron particles in one step, meeting stringent UHPLC injection purity requirements.
• Light-Sensitive Samples - Amber housing options shield photosensitive analytes from light during filtration for chromatographic preparation.
• 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.
