Grade A Glass Fiber Filter Paper 1.6um, 55mm, Nonsterile, 25/Pk SKU: EF19012

Glass Fiber (GF) Filter Paper - EF19012

Clarifying biological fluids and cell culture harvests requires depth filtration capacity that cellulose papers and surface-capture membranes cannot match. Hydrophilic glass surface wets immediately on contact with aqueous solutions, requiring no pre-conditioning before filtration begins. In turn, consistent physical properties across the full sheet area support uniform filtration results in both gravity and vacuum applications.

Key Filter Paper Characteristics

• Randomly oriented glass microfibers create a depth structure that captures particles throughout the matrix, not just at the surface.
• Nominal retention ratings defined by fiber diameter and packing density provide consistent particle capture across production lots.
• Chemically inert borosilicate composition resists acids, bases, and organic solvents across the full pH range without fiber degradation.
• At 53g/m² nominal basis weight, the filter medium provides the mass uniformity needed for reproducible gravimetric determinations.
• Borosilicate glass microfiber depth structure provides high particle loading capacity with flow rates significantly faster than cellulose papers of equivalent retention.

If your workflow includes both routine clarification and specialized quantitative methods, stocking this versatile grade reduces your inventory complexity. To that end, hydrophilic glass surface eliminates the pre-wetting steps your aqueous filtration protocols would otherwise require before processing begins. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.
