PVDF Syringeless Filters - UN203APEAQU

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. Hydrophilic PVDF suits HPLC sample preparation and aqueous clarification and preserves dilute proteins and analytes in the filtrate. The PP housing sustains efficient flow on viscous samples while holding extractables low for sensitive analyses and holds a reliable seal against the membrane edge. Cleaner, more uniform injections follow, giving the method the reproducibility that quantitative analysis depends on.

Technical Specifications

• Low extractables preserve a clean chromatographic baseline
• Ultra-low protein binding preserves dilute analytes for maximum recovery
• Thin membrane structure sustains high flow for fast sample throughput
• Hydrophilic surface wets aqueous and HPLC samples without pre-wetting
• Absolute pore size rating gives consistent results across protocols

Housing Specifications

• Low extractable contribution protects sensitive downstream analyses
• Medical-grade polypropylene with broad chemical compatibility
• Thermal-bonded construction keeps adhesives out of the fluid path
• Optimized internal geometry minimizes backpressure in service

Sample clarification before injection is the cheapest insurance your chromatography system has. Upstream sample clarification keeps your separations clean and reproducible with low UV-absorbing extractables in the filtrate.

• Bioanalytical Sample Cleanup - Low-binding membranes clarify plasma and serum extracts, retaining drug analytes for accurate quantitation.
• Protein Precipitation Cleanup - Low protein binding retains analyte integrity when filtering precipitated sample supernatants.
• HPLC Sample Prep - Plunger-driven filtration removes particulates from analytical samples, protecting columns from clogging and back pressure.
• Light-Sensitive Samples - Amber housing options shield photosensitive analytes from light during filtration for chromatographic preparation.
• UHPLC Prep Workflow - Integrated plunger and membrane filter sub-micron particles in one step, meeting stringent UHPLC injection purity requirements.
• Column Lifetime Extension - Consistent sub-micron particle removal before injection reduces column contamination and back pressure buildup.
