Grade B Glass Fiber Filter Paper 1.0um, 90mm, Nonsterile, 10/Pk SKU: EF19029

Glass Fiber (GF) Filter Paper - EF19029

Liquid scintillation counting and radioimmunoassay procedures need a binderless glass fiber substrate that introduces no chemical interference to sensitive detection methods. Binderless construction eliminates organic and resin-based additives that would contribute background contamination to sensitive downstream analytical methods. In combination, consistent physical properties across the full sheet area support uniform filtration results in both gravity and vacuum applications.

Key Filter Paper Characteristics

• Borosilicate glass microfiber construction provides depth filtration with loading capacity far exceeding cellulose papers of equivalent retention.
• Nominal retention ratings defined by fiber diameter and packing density provide consistent particle capture across production lots.
• Randomly oriented glass microfibers create a depth structure that captures particles throughout the matrix, not just at the surface.
• Binderless glass fiber construction delivers ultra-low blank values for gravimetric, thermal, and trace analytical methods requiring clean filter backgrounds.
• Hydrophilic glass surface wets spontaneously on contact with aqueous solutions, requiring no pre-conditioning before sample filtration.

If your laboratory runs standardized filtration protocols, the lot-level consistency of this filter paper protects your method reproducibility. Here, 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.
