Autovial 12 Syringeless Filter, Glass PreFilter, 0.2um, PVDF, 50 pcs
Whatman SKU: AV125EAQU

PVDF Syringeless Filters - AV125EAQU

A single syringeless device replaces the separate syringe, filter, and transfer vial, cutting both setup time and the handling steps where analyte is lost or contaminated. PVDF holds up to alcohols and mild hydrocarbon solvents and suits HPLC sample preparation and aqueous clarification. The PP housing prevents sample bypass under rated operating pressure while holding extractables low for sensitive analyses and sustains efficient flow on viscous samples. For the analyst, that consistency means chromatographic results with less run-to-run variability traced back to sample preparation.

Technical Specifications

• Absolute pore size rating gives consistent results across protocols
• Hydrophilic surface wets aqueous and HPLC samples without pre-wetting
• Low extractables preserve a clean chromatographic baseline
• Ultra-low protein binding preserves dilute analytes for maximum recovery
• Resists HPLC mobile phases, alcohols, and mild hydrocarbons

Housing Specifications

• Medical-grade polypropylene with broad chemical compatibility
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Low extractable contribution protects sensitive downstream analyses
• Optimized internal geometry minimizes backpressure in service

Consistent closures and low-extractable components keep your baselines clean across long autosampler queues. Consistent autosampler-ready components keep your chromatographic methods reproducible across routine and regulated analytical workflows. Ask our friendly customer service team to confirm the cap size, septa material, and thread your method requires.

• 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.
• Heavy Particulate Samples - Glass microfiber prefilter traps large debris through its fibrous depth, preventing premature membrane blockage.
• UHPLC Prep Workflow - Integrated plunger and membrane filter sub-micron particles in one step, meeting stringent UHPLC injection purity requirements.
• Direct Sample Filtration - Built-in membrane clarifies the sample in one manual step, cutting transfer steps before chromatographic injection.
• Protein Precipitation Cleanup - Low protein binding retains analyte integrity when filtering precipitated sample supernatants.
