PVDF Syringeless Filters - UN503NPEAQU

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. PVDF holds up to alcohols and mild hydrocarbon solvents and wets aqueous and HPLC samples on contact. Polypropylene construction maintains housing integrity through the filtration run while routing flow to minimize backpressure in service and resists degradation from routine sample matrices. Cleaner, more uniform injections follow, giving the method the reproducibility that quantitative analysis depends on.

Technical Specifications

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

Housing Specifications

• Low extractable contribution protects sensitive downstream analyses
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Thermal-bonded construction keeps adhesives out of the fluid path
• Reliable housing-to-membrane seal prevents bypass at rated pressure

Upstream clarification pays for itself by keeping your columns clear and your analytical day on schedule. Pre-injection filtration protects the resolution your methods depend on by clearing particulates ahead of the column and frits.

• Pharmaceutical QC Testing - Content uniformity and dissolution samples are clarified in one step, reducing handling before chromatographic injection.
• HPLC Sample Prep - Plunger-driven filtration removes particulates from analytical samples, protecting columns from clogging and back pressure.
• High-Throughput Prep - Disposable single-unit format speeds batch sample preparation by eliminating syringe assembly and cleanup between samples.
• Column Lifetime Extension - Consistent sub-micron particle removal before injection reduces column contamination and back pressure buildup.
• Solubility Assay Filtration - Positive-pressure filtration cleanly clarifies small sample volumes, supporting accurate solubility determination.
• UHPLC Prep Workflow - Integrated plunger and membrane filter sub-micron particles in one step, meeting stringent UHPLC injection purity requirements.
