GD/X 13mm Syringe Filter, Glass Microfiber Filteration Medium, 0.45um (150 pcs)
Whatman SKU: 6894-1304

Whatman GD/X Glass Fiber (GF) Syringe Filters, 0.45 µm, 13 mm, 150/Pk - 6894-1304

Whatman's brand recognition and documented performance history support specification in standardized analytical methods. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. Glass fiber stays biologically inert across a broad range of chemistries while capturing particulates throughout its depth and accepts water-based samples on contact. The polypropylene housing routes flow to minimize backpressure in service while holding extractables low for sensitive analyses and stays inert across common laboratory solvents. Where analytical results depend on clean samples, syringe filtration removes particulates at the moment of preparation.

Technical Specifications

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

Housing Specifications

• Resists aqueous acids, bases, and alcohols in routine sample prep
• Optimized internal geometry minimizes backpressure in service
• Medical-grade polypropylene with broad chemical compatibility
• Reliable housing-to-membrane seal prevents bypass at rated pressure

Reproducible separations start with samples that reach the column free of particulates. Upstream sample clarification keeps your separations clean and reproducible across your HPLC and UHPLC methods.
