GD/X 13mm Syringe Filter, Glass Microfiber GF/F Filteration Medium, 0.7um (150 pcs)
Whatman SKU: 6890-1307

Whatman GD/X Glass Fiber (GF) Syringe Filters, 0.7 µm, 13 mm, 150/Pk - 6890-1307

Whatman applies the same process controls across its filtration portfolio, verifying rated performance at the production lot level. Syringe filters give the analyst a single-use device for clarifying samples right at the bench. Glass microfiber holds structural integrity through high-temperature conditioning cycles and wets rapidly with aqueous samples. The polypropylene housing contributes minimal extractables to the filtrate and sustains efficient flow on viscous samples. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

• Naturally hydrophilic surface wets rapidly with aqueous samples
• Biologically inert borosilicate fiber with broad chemical compatibility
• Inorganic construction suits demanding sample-preparation chemistries
• Withstands high-temperature pre-conditioning up to 500°C
• 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
• Low extractable contribution protects sensitive downstream analyses
• Stable across the full aqueous pH range in routine sample work

Sample clarification before injection is the cheapest insurance your chromatography system has. Upstream sample clarification keeps your separations clean and reproducible so your filtrate reaches the column clean. Review our Chemical Compatibility Chart, or ask technical service to confirm chemical compatibility for your specific application.
