PVDF Syringeless Filters - AV115NPUAQU

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. PVDF delivers absolute particle cutoff at the rated pore size and resists HPLC mobile phases, alcohols, and mild hydrocarbons. The polypropylene housing contributes minimal extractables to the filtrate while holding a reliable seal against the membrane edge and resists aqueous acids, bases, and alcohols. For the analyst, that consistency means chromatographic results with less run-to-run variability traced back to sample preparation.

Technical Specifications

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

Housing Specifications

• Thermal-bonded construction keeps adhesives out of the fluid path
• Medical-grade polypropylene with broad chemical compatibility
• Low extractable contribution protects sensitive downstream analyses
• Resists aqueous acids, bases, and alcohols in routine sample prep

Protecting sample integrity from preparation through injection keeps your chromatographic results trustworthy. Dependable vial and closure performance protects your samples through every injection from sample preparation through the final run in the queue.

• Protein Precipitation Cleanup - Low protein binding retains analyte integrity when filtering precipitated sample supernatants.
• 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.
• Solubility Assay Filtration - Positive-pressure filtration cleanly clarifies small sample volumes, supporting accurate solubility determination.
• Pharmaceutical QC Testing - Content uniformity and dissolution samples are clarified in one step, reducing handling before chromatographic injection.
• Direct Sample Filtration - Built-in membrane clarifies the sample in one manual step, cutting transfer steps before chromatographic injection.
