Glass Fiber (GF) Syringeless Filters - AV115UGMF

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. Glass fiber captures particulates throughout its depth for high loading capacity while resisting chemical attack across diverse solvents and tolerates repeated high-temperature conditioning cycles. The polypropylene housing routes flow to minimize backpressure in service while maintaining housing integrity through the filtration run and holds extractables low for sensitive analyses. Standardized this way, sample preparation becomes one of the most controlled and repeatable steps in the analytical workflow.

Technical Specifications

• Nominal depth retention with high dirt-loading capacity
• Withstands high-temperature pre-conditioning up to 500°C
• Biologically inert borosilicate fiber with broad chemical compatibility
• Naturally hydrophilic surface wets rapidly with aqueous samples
• Inorganic construction suits demanding sample-preparation chemistries

Housing Specifications

• Optimized internal geometry minimizes backpressure in service
• Thermal-bonded construction keeps adhesives out of the fluid path
• Medical-grade polypropylene with broad chemical compatibility
• Low extractable contribution protects sensitive downstream analyses

Sample clarification before injection is the cheapest insurance your chromatography system has. Upstream sample clarification keeps your separations clean and reproducible with low UV-absorbing extractables in the filtrate. 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.
• HPLC Sample Prep - Plunger-driven filtration removes particulates from analytical samples, protecting columns from clogging and back pressure.
• Solubility Assay Filtration - Positive-pressure filtration cleanly clarifies small sample volumes, supporting accurate solubility determination.
• Direct Sample Filtration - Built-in membrane clarifies the sample in one manual step, cutting transfer steps before chromatographic injection.
• Pharmaceutical QC Testing - Content uniformity and dissolution samples are clarified in one step, reducing handling before chromatographic injection.
• UHPLC Prep Workflow - Integrated plunger and membrane filter sub-micron particles in one step, meeting stringent UHPLC injection purity requirements.
