GD/X 25mm Syringe Filter, Glass Microfiber Filteration Medium, 0.45um (150 pcs)
Whatman SKU: 6895-2504

Whatman GD/X Glass Fiber (GF) Syringe Filters, 0.45 µm, 25 mm, 150/Pk - 6895-2504

Whatman applies the same process controls across its filtration portfolio, verifying rated performance at the production lot level. Across analytical workflows, the syringe filter is where particulates leave the sample stream. Glass fiber withstands high-temperature pre-conditioning up to 500°C while delivering nominal retention as a depth medium and stays biologically inert across diverse chemistries. Polypropylene construction resists chemical degradation from routine sample matrices and maintains a low-dead-volume internal flow path. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

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

Housing Specifications

• Tough polypropylene body tolerates repeated handling at the bench
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Plasticizer-free polyolefin construction keeps the fluid path clean
• Resists aqueous acids, bases, and alcohols in routine sample prep

Sample clarification before injection is the cheapest insurance your chromatography system has. Upstream sample clarification keeps your separations clean and reproducible from sample preparation through final injection.
