Grade F Glass Fiber Filter Paper, 0.7um, 125mm, Nonsterile, 10 Pk SKU: EF19062

Glass Fiber (GF) Filter Paper - EF19062

Clarifying biological fluids and cell culture harvests requires depth filtration capacity that cellulose papers and surface-capture membranes cannot match. Binderless construction eliminates organic and resin-based additives that would contribute background contamination to sensitive downstream analytical methods. In effect, quality-controlled production produces filter paper with the documented consistency that reproducible analytical and preparative methods demand.

Key Filter Paper Characteristics

• Binderless glass fiber matrix eliminates organic extractables that would interfere with downstream chromatographic or spectroscopic determinations.
• 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.
• Nominal retention of 0.7um provides the particle size cutoff appropriate for the analytical or preparative separation method.
• Hydrophilic glass surface wets spontaneously on contact with aqueous solutions, requiring no pre-conditioning before sample filtration.

When your quality system requires documented specifications for every consumable, the grade data above provides the traceability your auditors expect. Under these conditions, hydrophilic glass surface eliminates the pre-wetting steps your aqueous filtration protocols would otherwise require before processing begins. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
