Glass Fiber (GF) Syringeless Filters - AV125UGMF

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. Glass fiber draws aqueous samples through without preconditioning while sustaining high dirt-loading capacity and resists chemical attack across diverse solvents. The polypropylene housing holds a reliable seal against the membrane edge while resisting degradation from routine sample matrices and holds extractables low for sensitive analyses. Cleaner, more uniform injections follow, giving the method the reproducibility that quantitative analysis depends on.

Technical Specifications

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

Housing Specifications

• Thermal-bonded construction keeps adhesives out of the fluid path
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Medical-grade polypropylene with broad chemical compatibility
• Optimized internal geometry minimizes backpressure in service

Reproducible separations start with samples that reach the column free of particulates. Upstream sample clarification keeps your separations clean and reproducible from sample preparation through final injection.

• Solubility Assay Filtration - Positive-pressure filtration cleanly clarifies small sample volumes, supporting accurate solubility determination.
• 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.
• 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.
• Light-Sensitive Samples - Amber housing options shield photosensitive analytes from light during filtration for chromatographic preparation.
