GD/X 25mm Syringe Filter, Glass Microfiber GF/A Filteration Medium, 1.6um (1500 pcs)
Whatman SKU: 6883-2516

Whatman GD/X Glass Fiber (GF) Syringe Filters, 1.6 µm, 25 mm, 150/Pk - 6883-2516

Whatman's expertise in cellulose, glass fiber, and polymeric membrane production guides material selection and quality control. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. The glass microfiber matrix delivers nominal retention as a depth medium while withstanding high-temperature pre-conditioning up to 500°C and draws aqueous samples through without preconditioning. The polypropylene housing resists aqueous acids, bases, and alcohols in routine use while routing flow to minimize backpressure in service and holds a reliable seal against the membrane edge. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Technical Specifications

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

Housing Specifications

• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Tough polypropylene body tolerates repeated handling at the bench
• Stable across the full aqueous pH range in routine sample work
• Optimized internal geometry minimizes backpressure in service

Filtering particulates upstream protects the column investment your methods depend on. Reliable particulate removal protects your instruments and your data so column life and baseline stability stay predictable.
