Grade B Glass Fiber Filter Paper 1.0um, 8 Inch x 10 Inch, Nonsterile, 25/Pk SKU: EF19015

Glass Fiber (GF) Filter Paper - EF19015

High-particulate samples that overwhelm cellulose filter papers demand a depth filter medium with the loading capacity to process the full sample volume. Randomly oriented borosilicate glass microfibers create a depth filtration matrix that captures particles throughout its thickness rather than solely at the surface. Ultimately, quality-controlled production produces filter paper with the documented consistency that reproducible analytical and preparative methods demand.

Key Filter Paper Characteristics

• Nominal retention ratings defined by fiber diameter and packing density provide consistent particle capture across production lots.
• Thermal stability exceeding 500 degrees C supports ignition-based gravimetric methods without filter decomposition or residue artifacts.
• 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.
• Depth filtration captures particles throughout the fiber matrix rather than at the surface, maximizing total loading capacity before flow restriction.

When your analytical procedure specifies a particular grade, the retention and purity characteristics documented above confirm method compliance. 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.
