Grade F Glass Fiber Filter Paper, 0.7um, 24mm, Nonsterile, 100/Pk SKU: EF19073

Glass Fiber (GF) Filter Paper - EF19073

Gravimetric analysis of suspended solids requires a thermally stable filter that survives ignition without contributing measurable residue to the determination. Randomly oriented borosilicate glass microfibers create a depth filtration matrix that captures particles throughout its thickness rather than solely at the surface. On this basis, quality-controlled production produces filter paper with the documented consistency that reproducible analytical and preparative methods demand.

Key Filter Paper Characteristics

• Hydrophilic glass surface wets spontaneously on contact with aqueous solutions, requiring no pre-conditioning before sample filtration.
• Pure borosilicate glass provides ultra-low blank values for trace analytical methods sensitive to organic or inorganic background contamination.
• Borosilicate glass microfiber construction provides depth filtration with loading capacity far exceeding cellulose papers of equivalent retention.
• Randomly oriented glass microfibers create a depth structure that captures particles throughout the matrix, not just at the surface.
• Chemically inert glass composition withstands acids, bases, and organic solvents across the full pH range without fiber degradation.

When your quality system requires documented specifications for every consumable, the grade data above provides the traceability your auditors expect. With these demands in mind, hydrophilic glass surface eliminates the pre-wetting steps your aqueous filtration protocols would otherwise require before processing begins. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
