PTFE Syringeless Filters - AV125UORG

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. PTFE suits solvent and reagent filtration where other membranes fail and delivers absolute particle cutoff at the rated pore size. Polypropylene construction resists chemical degradation from routine sample matrices and prevents sample bypass under rated operating pressure. Standardized this way, sample preparation becomes one of the most controlled and repeatable steps in the analytical workflow.

Technical Specifications

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

Housing Specifications

• Low extractable contribution protects sensitive downstream analyses
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Medical-grade polypropylene with broad chemical compatibility
• Optimized internal geometry minimizes backpressure in service

Holding a leak-free seal through every needle puncture keeps your injections clean from the first to the last. Dependable vial and closure performance protects your samples through every injection across HPLC, UPLC, and GC autosampler platforms. Contact Tisch Scientific for help matching vials, caps, and septa to your autosampler platform.

• Light-Sensitive Samples - Amber housing options shield photosensitive analytes from light during filtration for chromatographic preparation.
• 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.
• Heavy Particulate Samples - Glass microfiber prefilter traps large debris through its fibrous depth, preventing premature membrane blockage.
• Direct Sample Filtration - Built-in membrane clarifies the sample in one manual step, cutting transfer steps before chromatographic injection.
• High-Throughput Prep - Disposable single-unit format speeds batch sample preparation by eliminating syringe assembly and cleanup between samples.
