PVDF Syringeless Filters - US203NPEAQU

Syringeless filters consolidate the syringe-and-filter routine into one disposable assembly, reducing setup time and the multi-step handling that conventional filtration requires for each sample. Ultra-low-binding PVDF preserves dilute proteins and analytes in the filtrate while tolerating common chromatography solvents without degradation and wets aqueous and HPLC samples on contact. The polypropylene housing routes flow to minimize backpressure in service while resisting degradation from routine sample matrices and prevents sample bypass under rated operating pressure. Where high-throughput HPLC and UHPLC demand consistent injections, that uniformity keeps method performance predictable.

Technical Specifications

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

Housing Specifications

• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Low extractable contribution protects sensitive downstream analyses
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Optimized internal geometry minimizes backpressure in service

Sample clarification before injection is the cheapest insurance your chromatography system has. Pre-injection filtration protects the resolution your methods depend on across reversed-phase and normal-phase workflows.

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