GD/X 25mm Syringe Filter, Glass Microfiber GF/C Filteration Medium, 1.2um (150 pcs)
Whatman SKU: 6886-2512

Whatman GD/X Glass Fiber (GF) Syringe Filters, 1.2 µm, 25 mm, 150/Pk - 6886-2512

Whatman's brand recognition and documented performance history support specification in standardized analytical methods. Syringe filters mount on a syringe to clarify a sample in a single manual pass. The borosilicate glass matrix tolerates repeated high-temperature pre-conditioning while offering broad chemical compatibility and delivers nominal retention as a depth medium. Polypropylene construction maintains a low-dead-volume internal flow path while keeping the fluid path low in extractable contamination and stays inert across common laboratory solvents. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

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

Housing Specifications

• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Medical-grade polypropylene with broad chemical compatibility
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Resists aqueous acids, bases, and alcohols in routine sample prep

Filtering buffers, reagents, and aqueous samples keeps your preparation moving and consistent. Consistent aqueous clarification keeps your sample preparation moving as a dependable step in your aqueous sample prep. Review our Chemical Compatibility Chart, or ask technical service to confirm chemical compatibility for your specific application.
