Grade F Glass Fiber Filter Paper, 0.7um, 50mm, Nonsterile, 100/Pk SKU: EF19075

Glass Fiber (GF) Filter Paper - EF19075

Environmental laboratories processing high-volume water and air samples need a filter medium that combines fine retention with rapid throughput. Randomly oriented borosilicate glass microfibers create a depth filtration matrix that captures particles throughout its thickness rather than solely at the surface. Consistent physical properties across the full sheet area support uniform filtration results in both gravity and vacuum applications.

Key Filter Paper Characteristics

• Rated at 0.7um particle retention, the fiber matrix provides a defined cutoff for consistent separation across analytical batches.
• Borosilicate glass microfiber construction provides depth filtration with loading capacity far exceeding cellulose papers of equivalent retention.
• High void volume between randomly packed fibers sustains rapid flow rates even as accumulated particulate loading increases during filtration.
• Inorganic glass matrix withstands temperatures exceeding 500 degrees C, supporting ignition-based gravimetric methods without filter decomposition.
• Depth filtration captures particles throughout the fiber matrix rather than at the surface, maximizing total loading capacity before flow restriction.

Your sample preparation workflow benefits from a filter paper whose performance is defined, documented, and consistent from one purchase to the next. Rapid flow rates through the glass microfiber matrix reduce the processing time your high-volume filtration workflows demand. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
