GD/X 25mm Syringe Filter, Glass Microfiber GF/F Filteration Medium, 0.7um (150 pcs)
Whatman SKU: 6890-2507

Whatman GD/X Glass Fiber (GF) Syringe Filters, 0.7 µm, 25 mm, 150/Pk - 6890-2507

Whatman applies over a century of filtration media expertise, manufacturing under the quality standards that established its products as global laboratory references. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. Inorganic glass fiber offers broad chemical compatibility for demanding samples while drawing aqueous samples through without preconditioning and captures particulates throughout its depth. Polypropylene construction holds extractable contribution low for sensitive analyses while routing flow to minimize backpressure in service and maintains housing integrity through the filtration run. When chromatographic methods demand particle-free injections, point-of-use syringe filtration clarifies the sample before it reaches the column.

Technical Specifications

• 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
• Nominal depth retention with high dirt-loading capacity
• Inorganic construction suits demanding sample-preparation chemistries

Housing Specifications

• Medical-grade polypropylene with broad chemical compatibility
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Low extractable contribution protects sensitive downstream analyses
• Rigid polypropylene body holds its shape under manual filtration pressure

Clarify your routine aqueous samples in a single pass and cut down on juggling multiple filter types at the bench. Consistent aqueous clarification keeps your sample preparation moving across the buffers and reagents your methods rely on.
