Nylon Syringeless Filters - UN503NPENYL

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. The nylon membrane holds dimensional stability under rated backpressure and stays stable across the pH 3 to 12 buffer range. The polypropylene housing contributes minimal extractables to the filtrate and stays inert across common laboratory solvents. Where high-throughput HPLC and UHPLC demand consistent injections, that uniformity keeps method performance predictable.

Technical Specifications

• Alkaline-resistant across a broad range of aqueous buffers
• Stable across the pH 3 to 12 operating range
• High tensile strength for stability under elevated differential pressures
• Low extractable contribution to sensitive analytical preparations
• Absolute pore size rating provides consistent results across filtration protocols

Housing Specifications

• Medical-grade polypropylene with broad chemical compatibility
• Optimized internal geometry minimizes backpressure in service
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Thermal-bonded construction keeps adhesives out of the fluid path

Consistent closures and low-extractable components keep your baselines clean across long autosampler queues. Consistent autosampler-ready components keep your chromatographic methods reproducible so injection-to-injection variability stays low. Contact Tisch Scientific for help matching vials, caps, and septa to your autosampler platform.

• HPLC Sample Prep - Plunger-driven filtration removes particulates from analytical samples, protecting columns from clogging and back pressure.
• Aqueous Biological Matrices - Nylon membrane filters aqueous and mixed-solvent samples without pre-wetting, maintaining flow for routine prep.
• UHPLC Prep Workflow - Integrated plunger and membrane filter sub-micron particles in one step, meeting stringent UHPLC injection purity requirements.
• High-Throughput Prep - Disposable single-unit format speeds batch sample preparation by eliminating syringe assembly and cleanup between samples.
• Direct Sample Filtration - Built-in membrane clarifies the sample in one manual step, cutting transfer steps before chromatographic injection.
• Light-Sensitive Samples - Amber housing options shield photosensitive analytes from light during filtration for chromatographic preparation.
