PTFE Syringeless Filters - AV115NPEORG

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. The PTFE matrix handles concentrated acids and bases across demanding methods and stays chemically inert against solvents, acids, and alkalis. The polypropylene housing resists aqueous acids, bases, and alcohols and maintains a low-dead-volume internal flow path. Standardized this way, sample preparation becomes one of the most controlled and repeatable steps in the analytical workflow.

Technical Specifications

• Chemically inert against aggressive solvents, strong acids, and alkalis
• Stable across a wide operating temperature range for demanding methods
• Filters aggressive organic solvents without swelling or breakdown
• Absolute pore size rating gives consistent results across protocols
• Low extractables keep the chromatographic background clean

Housing Specifications

• Medical-grade polypropylene with broad chemical compatibility
• Thermal-bonded construction keeps adhesives out of the fluid path
• Low extractable contribution protects sensitive downstream analyses
• 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. Connect with our customer support technicians to standardize vials, caps, and septa across your chromatography workflows.

• High-Throughput Prep - Disposable single-unit format speeds batch sample preparation by eliminating syringe assembly and cleanup between samples.
• Aggressive Solvent Matrices - PTFE membrane withstands organic solvents, enabling reliable clarification of solvent-matched sample matrices.
• 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.
• 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.
